Nanocrystalline diamond piezoresistive sensor
Vacuum, 2009The design, fabrication and test of piezoresistive sensors based on nanocrystalline diamond (NCD) films are reported. The CoventorWare FEM calculations of the mechanical stress and geometrical deformations of a 3-D structure are used for a proper localization of the piezoresistor on the carrying substrate. The boron-doped piezoresistive sensing element

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

Monolithic piezoresistive CMOS magnetic field sensors
Sensors and Actuators A: Physical, 2003Abstract Two original electromechanical magnetic sensors have been developed using a fully industrial fabrication process that relies on bulk wet etching of CMOS dies. The first device uses the Lorentz force to actuate a U-shaped cantilever beam, while piezoresistive polysilicon gauges convert the beam bending into an electrical signal. A 2 μT sensor

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.

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 ...

A silicon piezoresistive pressure sensor
Proceedings First IEEE International Workshop on Electronic Design, Test and Applications '2002, 2003The paper describes the design, simulation and fabrication of a silicon pressure sensor. The device makes use a of monocrystalline silicon square diaphragm supported by a thick silicon rim. The diaphragm is fabricated by etching away the bulk silicon on a defined region until the required thickness is achieved.

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.

Highly piezoresistive hybrid MEMS sensors
Sensors and Actuators A: Physical, 2014Abstract A flexible organic piezoresistive micro-electro-mechanical system (MEMS) strain sensor with enhanced sensitivity is presented. The piezoresistive transducers consist in CNT/SU-8 nanocomposites. The electrical resistance changes versus strain of CNT/SU-8 piezoresistive materials have shown linear and non-linear regions at low and high strain ...

Semiconductor Sensors: II—Piezoresistive Devices
IEEE Transactions on Industrial Electronics and Control Instrumentation, 1970This paper presents a survey of the recent developments of piezoresistive sensors. First, the physical concepts which are essential for the understanding of these devices are recalled, and the characteristics and limitations (particularly temperature limitations) of semiconductor strain gauges are discussed. A further section is devoted to strain-gauge
