Exposition

The exposition included various systems developed at ITE:

• Impedancemetric and potentiometric pH sensors based on ruthenium dioxide developed during the SENSEIVER project (the sensors were also part of the laboratory)
• Toxic gas sensors based on samarium cobaltite
• LTCC-based systems, including an implantable neurostimulator and a water conductivity meter.

Two of the systems demonstrated practical use of piezopolymeric force transducers. One was a system for measuring foot pressure on the ground during walking, comprised of a piezopolymeric shoe insole and a wireless data transmission module. The insole measures forces in eight points of foot simultaneously. The measured force is transmitted 60 times per second to a computer or a cell phone for real-time diagnostics of motion.

The other system used piezopolymers for a fall detection system dedicated for use by bicycle riders. The main element of the system is a bicycle helmet with elastic force transducers glued to it. If a helmet user falls, the sensors will detect a shock. The information is relayed via a Bluetooth link to the user’s cell phone. A cell phone application then gives aural signal and displays a warning message. If the application is not closed by the user, it automatically sends GPS coordinates of the event in an SMS message to a preconfigured number.

The landing of Rosetta probe on a comet took place during the fair. It was a great opportunity to exhibit two Rosetta spacecraft components developed at ITE. One of the components was a carbon based resistor used in MUPUS experiment for measuring ice hardness. The second component was a ceramic resistor used for burning through a nylon rope in order to release harpoons on landing.
