Improved composite piezoresistive strain sensors

SPIE Proceedings, 1996
The relationship between strain and the fractional increase in electrical resistance ((Delta) R/Ro) of piezoresistive polyether-sulfone-matrix composite strain sensors was found to be much more linear and less noisy when the electrically conducting filler was 0.1 micrometer-diameter carbon filaments rather than the conventionally used 10 micrometer ...

Noise in piezoresistive pressure sensors

2015 International Conference on Noise and Fluctuations (ICNF), 2015
In 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.

Harsh environment piezoresistive pressure sensors

2017 IEEE SENSORS, 2017
The capability to ensure reliability while operating in extreme environments is important for the most demanding automotive applications. Even though pressure sensors are a well-established area in the MEMS industry, improvements in sensor design are needed to deliver reliability and long operational life. This paper reports the design, fabrication and

Self-compensating piezoresistive pressure sensor

Sensors and Actuators A: Physical, 1994
Abstract A double-bridge method of pressure-sensor compensation has been tested. Three types of sensors are produced: standard with a flat, square, thin membrane and single Wheatstone bridge with four diffused piezoresistors in standard configuration and new sensors with ‘cut’ piezoresistors and a flat or bossed square membrane with two identical ...

A piezoresistive integrated pressure sensor

Sensors and Actuators, 1983
Abstract A silicon piezoresistive integrated pressure sensor (IPS) containing sensing, temperature compensation and amplification circuits has been developed for automotive and industrial applications, etc. The chip of the IPS is bonded on a silicon support 2 mm thick, using an electrostatic bonding technique for reducing unwanted thermal stress from

Frequency output piezoresistive pressure sensor

Sensors and Actuators, 1983
Abstract The sensitivity of silicon to strain and its application to the fabrication of integrated circuits enable sensors to be designed which provide the primary sensing and digital encoding of the signal within the same piece of material. One possible configuration, originally described by Reichl, uses a resistor as the basic sensor to vary the ...

Textile Piezoresistive Sensors for Biomechanical Variables Monitoring

2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006
In 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 ...

Piezoresistive thick.film sensors

1994
Sensors of strain-related mechanical quantities relying on the piezoresistive properties of thick-film resistors are being increasingly employed in various measuring and control systems; the purpose of this section is to explain how and why thick-film strain gauges differ from metal and semiconductor strain gauges widely employed in similar devices ...

Electro-elastic simulation of a piezoresistive pressure sensor

Microelectronics Journal, 1993
Transport properties of the silicon crystal are sensitive, to some extent, to mechanical perturbations: this allows for integrating mechanical sensors, together with the sensing circuitry, within a silicon chip by using an almost standard IC technology.

Paper-based piezoresistive MEMS force sensors

2011 IEEE 24th International Conference on Micro Electro Mechanical Systems, 2011
This paper describes the development of piezoresistive MEMS force sensors constructed using paper as the structural material. The sensing principle of the paper-based sensor is based on the piezoresistive effect of conductive materials patterned on a paper substrate.
