Measuring Permafrost in the Swiss Alps
Customer: ETH Zurich [TIK]
Permafrost is a thermal subsurface phenomenon; made-up of rock, ground and debris which is frozen throughout the year within the steep alpine bedrock. Not visible at the surface, Permafrost thaws during the summer months and can seriously affect slope stability leading to dangerous natural hazards which may hinder the safe operation of man-made infrastructure in the surrounding area.
PermaSense devices are installed and operated at high altitude in mountain regions with a permafrost environment. As such, the system and all of its component parts must run reliably at low temperatures and be able to withstand large, daily temperature changes (in excess of 40°C) depending on sun irradiation, wind and snow. Due to the fact that the PermaSense devices are only accessible by helicopter during summer, making a 2 - 3 year maintenance-free operation absolutely mandatory, the design of the system also had to take into consideration the following, in order to ensure long-term, reliable operation:
- extreme daily weather variations
- danger from lightning, avalanches, rockfall, frost / ice and snow
- limited power available from the battery
- restricted space for electronics and battery
- low production volumes & time frame
Data is collected via a flexible, distributed wireless sensor network (WSN) which has been specially adapted to the geophysical sensors, thereby enabling reliable and high-quality measurements in the extreme environmental conditions. The system developed featured, in addition to the in-mast integration of the GPS receiver and antenna, a 2-axis inclinometer, all electronics and cables and a 12V photovoltaic system, the following:
- wireless system with low latency data transmission

«AMON» Alarm & medical MONitor
Customer: European Commission, 5th Framework Project (FP5)
«AMON» is a wearable medical monitoring and alert system targeting high-risk cardiac respiratory patients. The main objective of the AMON project was to research, develop and validate an advanced, wearable personal health system to monitor and evaluate human vital signs using advanced bio-sensors. The scientific and technological challenge was to design a wearable monitoring device that will be small, dependable and contain the necessary data for an impending medical emergency.
The system developed includes continuous collection and evaluation of these vital signs, intelligent multi-parameter medical emergency detection and transmission of the data to a remote telemedicine centre, for further analysis and emergency care using a GSM/UMTS cellular infrastructure. The development & testing of the on-line Telemedicine Centre was conducted in parallel, including system testing, validation & assessment by end-users in hospitals around Europe. Using «AMON», patients who are not confined to hospital (including the high risk and elderly) are able to continuously monitor and analyse their vital signs, providing care at the point and time of need, increasing freedom of movement and enhancing overall quality of life.
The wrist mounted monitoring device (WMD) developed includes algorithms and sensors to monitor human vital health parameters such as heart rate, heart rhythm, 2-lead ECG, blood pressure, SpO2 blood saturation, skin perspiration and body temperature. Applying aggressive low-power design techniques enabled the whole system to be integrated into a wrist-worn device, continuous long-term monitoring without interfering with the patients' everyday activities or restricting their mobility.

«EMERGE»ncy Monitoring & Prevention
European Commission, 6th Framework Project (FP6)
Demographic trends in most European countries are forecasting a massive increase in the elderly population and a dramatic increase in emergency situations. Elderly people living alone are especially endangered as delays in alerting medical emergency services often leads to prolonged hospital stays resulting in an increasing number of elderly people being placed in nursing homes; at significant additional cost and an unnecessary deterioration in their quality of life. It has been recognised that daily activities are an important part of the functional health status and are often influenced by habits, age, culture, day of the week and the time of year. Activities like sleeping, going to the toilet, preparing meals and general mobility, which follow certain individual stereotypes have shown to be sensitive to changes in daily routines.
The «EMERGE» project was tasked with researching ways to improve the support of elderly people, with innovative emergency detection and prevention systems. The main objectives of the project being:
- immediate detection of an emergency: enabling reduced reaction times and early initiation of definitive help
- early recognition of a problem’s nature and severity: enabling adequate multilevel reaction, with close integration of social environment, caregivers, EMS and emergency physicians
- emergency prevention by early detection of changes in behavioural patterns: analysis of user behaviour and personal tracking enables detection of critical deviations which may indicate deterioration in health status and helps anticipation of potential emergencies
- minimum implication on the elderly user’s habitual lifestyle: ambient and non-obtrusive technology leads to higher user acceptance
How does the «EMERGE» System work?
The system collects and analyses data on an on-going basis from various data sources, e.g.
- ambient and unobtrusive sensors that acquire environmental information (e.g. temperature, humidity, and light intensity)
- activity information (e.g. usage of environmental objects determined by pressure sensors and contact switches, and usage of devices determined by energy consumption sensors)
- location tracking information acquired by active and passive sensor systems (e.g. RFID carpets, Ultra Wide Band (UWB) sensors, ultrasonic and infrared presence sensors)
- vital health parameters are acquired using sensors integrated into a wrist wearable device which measures pulse rate and skin temperature
- stand-alone devices measuring blood pressure and body weight can also be integrated into the system
European Commission, 6th Framework Project (FP6)
Developed during the EMERGE project, the SensoWatch is a key part of the system; an automatic monitoring device that incorporates multiple sensors into a single wrist device, enabling continuous monitoring of several ;important health parameters, e.g.
- pulse, skin temperature
- movement measurement in all 3 dimensions, lack of movement, overall activity
- acceleration (impact recognition followed by a period of no movement raises a fall alarm)
Medical personnel are notified immediately in the event of unexpected (or serious) deviations, enabling them to respond appropriately and quickly. Continuous monitoring allows an alarm to be raised in the event of potential helplessness (e.g. after a fall or loss of consciousness) without active intervention by the user. Even in the absence of an impact, a no movement alarm is raised if the person is helpless. No alarm is sent if the person stands up immediately after the fall...this enables every fall to be recognised while helping to avoid false alarms.
Worn like a normal everyday wristwatch, the SensoWatch continuously transmits data to a base station and (if necessary) a call for help, without adversely affecting a person’s mobility, thereby greatly increasing the ability of the wearer to continue to lead an active life. The timely provision of information to caregivers in an emergency or in the case of long term deviations or inconsistencies is an essential prerequisite for the independent life of elderly people in their preferred environment…at home!
- alarm button that can be activated by the user to call for help
- “forget-me-not” alarm (if not being worn during the day)
- low battery alarm, internal re-chargeable battery
- compact design (actual weight is only 46g)
- unobtrusive continuous measurements
- USB connection (for PC configuration)
Lenz - intelligent anti-snoring system
Customer: Earsonic GmbH
When we are awake throat muscles keep the throat open so that air can flow smoothly during breathing. During sleep the area at the back of the throat sometimes narrows as these muscles relax and the turbulent airflow can cause the tissues of roof of the mouth (soft palate) and the throat to vibrate, which in turn can cause the sounds of snoring.
Possible causes of snoring are:
- overeating, lack of exercise
- alcohol, sleeping pills, smoking
- allergies, nasal congestion, small or narrowed nostrils
- sleeping position, breathing through the mouth or tongue vibration
The Lenz is a patented anti-snoring aid that has been digitised and miniaturised especially for use in the ear. This high-tech device responds to your snoring with a gentle beep... you change your sleeping position and stop snoring, without waking or side effects. The Lenz is comfortable to wear and virtually invisible allowing you - and your partner - to sleep peacefully and undisturbed.
- Development of functional principles and algorithms
- Design and development of prototypes (hardware and software)
- Redesign of the software on the OEM device
- Extensive testing, verification and validation of the device
- Create production tests
- Support for the CE approval

«POLAR» Gamma Ray Burst Polarimeter
Customer: European Space Agency (ESA)
Despite being discovered in 1960 (Vela satellites) Gamma Ray Bursts (GRBs) are still full of mystery and the production mechanism of these very intense explosions in the universe is still unknown. To validate or exclude existing models about their creation, a precise measurement of the polarisation of the GRB is essential.
«POLAR» is a highly sensitive detector using the Compton Scattering Effect to measure the polarisation of incoming photons. With its large Field of View and a detection energy up to 500 keV «POLAR» will measure the polarisation of GRB emissions using low Z material Plastic Scintillators, multimode Photomultipliers and multi-channel ASIC Front-end Electronics.
«POLAR» is scheduled for two to three years operation in space during which a large number of GRBs are expected to be measured.
Construction of the «POLAR» detector, the only non-Chinese experiment onboard the Chinese space laboratory "Tiangong-2" was performed by an international collaboration project with contributions from China, France, Poland and Switzerland. Art of Technology responsibilities included:

«SEIS-EL» Seismometer Electronics
Customer: Contraves Space AG
The NETLANDERTM mission planned to send a network of four identical landers to the surface of Mars to perform simultaneous measurements in order to study the internal structure of Mars, its sub-surface and its atmosphere.
To fulfil the mission objectives with respect to the interior, subsurface, atmosphere and ionosphere investigation of MARS, each the 4 landers was to carry a payload composed of nine instruments. With a mass of the surface modules limited to 22kg, of which only 5.2kg was allowed for scientific instruments, the ultimate goal was to estimate possible mass / volume reductions (and cost) and to provide a recommendation for the most suitable approach and technology.

«STIX» Detector Electronics Module
Customer: Almatech Sàrl
Art of Technology, together with prime contractor Almatech Sarl, has been awarded a contract by the European Space Agency (ESA) for the design, development, production and supply of the Detector Electronics Module (DEM) to be used in the «STIX» instrument... a Swiss experiment on board Solar Orbiter, which is scheduled for launch in 2018.
The Solar Orbiter mission will address the central question of helio-physics, i.e. how does the Sun create and control the heliosphere?
Carrying the X-ray telescope «STIX», being developed and built under the direction of the University of Applied Sciences Northwestern Switzerland (FHNW), Solar Orbiter will travel to ¼ of the distance between the Earth and the Sun (closer to the Sun than any other spacecraft to date) allowing observations of the Sun with unprecedented sharpness and direct measurement of the solar wind and charged particles close to their point of origin.
Solar Orbiter will turn with the sun, allowing a certain area on the surface to be observed for extended periods of time without interruption, providing new insights into the activities of the sun and its effects on the earth, e.g. better prediction of high-energy energetic particles which can interfere with technical equipment such as radio and satellite communications on Earth. This new orbit will allow us to study the Earth side facing away from the sun and for the first time, the polar regions.
The objective of the «STIX» instrument (Spectrometer Telescope for Imaging X-ray) is to contribute to understanding the mechanisms behind the acceleration of electrons at the Sun and their transport into the interplanetary space.
«STIX» will also play a key role in linking remote-sensing and in-situ observations on Solar Orbiter with imaging spectroscopy of solar thermal and non-thermal X-ray emissions providing quantitative information on the timing, location, intensity and spectra of accelerated electrons as well as of high temperature thermal plasmas, which are mostly associated with flares or micro-flares in the solar corona and chromosphere.
European Commission, 4th Framework Project (FP4)
The rapidly changing market for embedded and portable computing exhibits a steadily growing demand for improved reliability and increasing processing performance in progressively smaller form factors. A Pentium® based Multi-Chip-Module (MCM) was designed and manufactured during the 4th Framework project «EUROPRACTICE MCM». The main scientific and technical challenge of the project was to develop a technology demonstrator to show the potential of High Density Packaging (HDP) technologies.
Advantages of MCM-based solutions
- simplification of system design
- internal routing of high-speed host bus signals reduces power consumption and ringing
- high frequencies and critical signals remain inside the MCM
- standard simple interfaces (PCI, DRAM)
- reduction of the number of signal layers on the motherboard
- less aggressive board design rules
- reduction of motherboard area
- significant reduction in size (¼ of the original size)
- overall weight reduction
- easily upgradable (new processors / chipsets)
- reduces time-to-market (no changes of motherboard required)
- improved EMC and Thermal performance
- end-user needs no Pentium knowledge
The Pentium® MCM was mounted on thermally enhanced Plastic-Stud-Grid-Array (PSGA), a packaging technology using plastic studs moulded to the body of the package instead of large solder balls, which provides reliable, low cost packaging of high pin-count devices. An existing Pentium® module chipset with 2nd level cache (9 chips plus SMD components), DRAM interface and PCI host-bridge was used with thin film on silicon in a PSGA housing which was significantly smaller than the original packaged Pentium®processor, i.e. 25% of the original packaged Pentium®
The SP5MX1 is a miniaturised version of the core of a Pentium® processor based Multi-Chip-Module (MCM) which is intended as a processor subsystem for use in mobile and embedded systems. First tests were successfully carried out with Windows NT running and some benchmark programs at a clock frequency of 100 MHz.
«LAP» Large Area Panel processing
European Commission, 4th Framework Project (FP4)
Thin film High Density Integration (HDI) offers the ultimate solution for many existing and new applications requiring either high electrical performance, smaller size, or both. However, the costs of these types of substrates has always been prohibitive.
The EU consortium «LAP» was formed to reduce the cost for thin-film substrates; the main goal of the project being the development and demonstration of low cost, high-density substrate manufacturing technology for first level die assemblies. i.e.
- high density / low cost substrate technology
- high performance MCM-D technology (50 µm line pitch & 50 µm via)
- verification by prototyping on a LAP pilot line
- compatibility of the LAP technologies of 3 manufacturers (within specified design rules)
- verification of LAP technologies developed via 3 product demonstrators
Benefit of LAP technology
The substrate technologies developed allowed for a wide range of packaging options from inserted substrates into transfer-moulded packages to integrated MCM-L/D and MCM-M/D (M=metal) area array packages. This ongoing trend towards miniaturisation, increased functionality and higher frequencies offers several significant challenges, e.g.
- increased functionality requires higher level of integration
- high frequency applications demand high signal integrity
- increased average component I/O density require still higher interconnect density
- direct chip attach to board (COB) is increasing as this gives the lowest inductance and noise, combined with the highest I/O density
- several chips in one package (MCM) or even a systems in a package (SIP) development are driven by increased functionality, reduced size and lower cost
Suitability of LAP technology was further demonstrated with the commercial implementation of a 9:4 satellite switch operating up to 2.4GHz.
«SMM» Solderable Memory Module
Customer: Art of Technology AG (internal project)
An elegant solution for industrial and medical applications providing a compact memory module with an electrical SD / MMC interface which is soldered directly onto a printed circuit board.
With a size of 24 x 20 mm2 and a pitch of only 1.27 mm, it is significantly smaller than a standard SD / MMC card, has less demands on board design and can be used wherever space considerations are critical. Moreover, with a controlled Bill of Material (BOM) problems resulting from hardware and firmware changes to the NAND Flash controller are now a thing of the past.
Customised functions such as password protection, emergency deletion can also be realised. With it's small form factor the SMM is the ideal choice for embedded systems in extremely demanding applications and environments.
