An embedded polymer piezoresistive microcantilever sensor
Ultramicroscopy, 2003We have developed a new type of chemical microsensor based on piezoresistive microcantilever technology. In this embedded polymer microsensor, a piezoresistive microcantilever is partially "embedded" into a polymeric material. Swelling of the polymer upon analyte exposure is measured as a simple resistance change in the embedded cantilever.

Textile Piezoresistive Sensors for Biomechanical Variables Monitoring
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006In this paper is described the study leading to the implementation of two novel classes of textile piezoresistive sensors, for application in the field of post stroke rehabilitation and cardiovascular diseases monitoring. Two different approaches have been used, the first one leading to the realization of knitted transducer fabric to be integrated in ...

In contrast to the fixed strain incorporated in logic devices for a fixed or constant improvement in device performance, piezoresistive strain sensors respond to variable strain through a modulation in the device resistance. The underlying physics of performance improvement in logic devices and strain transduction in piezoresistive strain sensors is ...

Differential Piezoresistive Pressure Sensor
2007 International Semiconductor Conference, 2007The pressure microsensor presented in this paper is based on a thin, elastic membrane, with boron implanted piezoresistive elements included, positioned in the maximum mechanical stress areas on the membrane. The pressure range for the developed sensors is in the 0divide400 mbar range, and this is the main novelty of this device.

Piezoresistive sensors for smart textiles
SPIE Proceedings, 2007We have used inkjet printing to deposit silver conducting lines and small PEDOT (conducting polymer) sensors onto fabrics. The printed conductors penetrate into the fabric and can be shown to coat the individual fibers within the yarn, through the full thickness of the cloth.

Noise in piezoresistive pressure sensors
2015 International Conference on Noise and Fluctuations (ICNF), 2015In this paper we present the results of noise analysis in piezoresistive ceramic pressure sensors (CPSs) prepared by low temperature co-fired ceramics (LTCC) technology. For this study a piezoresistive CPSs in a full Wheatstone-bridge configuration were prepared. Low frequency noise measurements can be used for the quality evaluation of CPSs.
