Each pane instantiates a major function - e.g. inertial sensing, tactile sensing or data collection and transmission. As opposed to similar architectures, this system treats the sensor panes as discrete design objects that have data collection as their primary goal. This architecture has allowed us to develop a shoe-mounted system that is capable of measuring gait parameters outside of a traditional motion laboratory. The small size of the circuit boards allows for a compact attachment that fits on the back of the shoe, and the integrated wireless transceiver allows the data to be collected continuously and in any environment.","PeriodicalId":369277,"journal":{"name":"Proceedings of IEEE Sensors 2003 (IEEE Cat.

The force sensor can not only show a gradual change in electrical resistivity with applied quasi-static pressure, but also measure the changes of compression stress relaxation in soft substrates under it. Furthermore, it is flexible and thin (1.2 mm) enough to be adhered on the measured soft substrates, so the result of relaxation can be obtained directly instead of presumption from sample testing.","PeriodicalId":369277,"journal":{"name":"Proceedings of IEEE Sensors 2003 (IEEE Cat.

The thickness of the sensing layers was 5 /spl mu/m and particle size was around 50 nm. Each chip contains four thin silicon nitride membranes, in the center of which a polysilicon heating resistor, insulating layers, platinum electrodes and sensitive layer are stacked. Unlike in previously reported works, the technological procedure reported here allows for depositing the sensing layers before the membranes have been etched. This avoids damaging the membranes during film deposition, which leads to gas sensor microsystems with an excellent fabrication yield (Llobet et al., 2003). The deposition method overcomes disadvantages such as low porosity and low surface area, generally associated to chemical vapor deposition or sputtering methods, and keeps power consumption low (80 mW for a working temperature of 480/spl deg/C). As an example, the sensor response to ammonia, NO/sub 2/, ethanol, CO and methane was studied. The sensors were very sensitive to NO/sub 2/ vapors. The influences of the sensor operating temperature and electrode geometry were also investigated.","PeriodicalId":369277,"journal":{"name":"Proceedings of IEEE Sensors 2003 (IEEE Cat.

In both cases we present results from numerical simulations. In addition, for the case of dielectric film characterization we present some preliminary experimental results to corroborate the proposed methodology.","PeriodicalId":369277,"journal":{"name":"Proceedings of IEEE Sensors 2003 (IEEE Cat.

This led to the perspective of using EMR devices in magnetic-field sensors and ultrafast read heads. Based on the finite element method, we study the EMR and optimize the effect with respect to material parameters and geometry. As the important design rule we find that the width-to-length ratio of a rectangular device should be below 0.042.

The quenchometric operation of the oxygen sensor coupled with CMOS detectors is compared to standard laboratory detection systems (CCD and PMT). The Stern-Volmer quenching constant (k/sub SV/) is used as a comparative measure of the operation of each of these systems. In our initial experiments all three systems yielded a k/sub SV/ between 0.042 and 0.049 O/sub 2/%/sup -1/. The xerogel sensor elements have demonstrated satisfactory reusability and stability over a period of more than six months.
