A Chipless Piezoresistive Strain Sensor
2023 17th European Conference on Antennas and Propagation (EuCAP), 2023Strain sensors are widely used in various applications and, depending on the specific application, it is necessary they operate completely wireless. The first step for the realization of a wireless strain sensor is the choice of the transducing material. Piezoresistive materials, whose surface impedance varies when a mechanical stimulus is applied, are

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.

Piezoresistive sensors: the pressure goes on
Sensor Review, 1989Advancements in producing piezoresistive pressure sensors have opened up exciting new markets for these pressure determining devices. Up to 10 times more sensitive than the old transducers, and with response times as rapid as a millisecond, the new sensors are used in applications as diverse as automotive, hi‐fi, aerospace and medical equipment ...
