C-V characterization of the piezocapacitive effect with a microfabricated cantilever

2012 IEEE 25th International Conference on Micro Electro Mechanical Systems (MEMS), 2012
The piezocapacitve effect of an n-type MOS capacitor is experimentally studied with a micro-fabricated cantilever. It shows that besides the geometrical effect, the stress induced dielectric constant change also contributes to the piezocapacitive behavior.

Piezoelectric-piezocapacitive hybrid sensor based on electrospun Poly(vinylidene fluoride)-Poly(octafluoropentyl acrylate)-sulphonated Poly(phenylene sulfide) blend nanofiber

Sensors and Actuators A: Physical, 2021
Abstract In this study, sulfonated Poly(phenylidene sulfide) (sPPS) of varying content (0, 3, 5, 7 and 10 wt.-%) is used as a filler to study the β-crystalline phase changes in electrospun Poly(vinylidene fluoride) (PVDF)-Poly(octafluoropentyl acrylate) (POFPA) blend (90/10 ratio, abbreviated as P-PFA) nanofiber.

Giant piezomagnetism, piezocapacitance, and piezoimpedance effects in MnZn ferrite device under hydrostatic pressure

Journal of Applied Physics, 2008
The effects of hydrostatic pressure on the magnetism, capacitance, and impedance of a manganese zinc ferrite device have been investigated. Giant piezomagnetism, piezocapacitance, and piezoimpedance that are independent of skin effects have been observed simultaneously under a pressure of a few megapascals.

Characterization of drift and hysteresis errors in force sensing resistors considering their piezocapacitive effect

2017 IEEE SENSORS, 2017
Force Sensing Resistors (FSRs) are low-cost alternatives to load cells for pressure and force sensing. Nonetheless, FSRs exhibit a comparative lower repeatability due to their large hysteresis and creep response. The FSRs operate on the basis of the piezoresistive effect, but they have proven to exhibit a piezocapacitive effect too.

Thermochromic and Piezocapacitive Flexible Sensor Array by Combining Composite Elastomer Dielectrics and Transparent Ionic Hydrogel Electrodes

Advanced Materials Technologies, 2019
AbstractElectronic skin (e‐skin) is an important building block to achieve human–machine interfaces, functional prostheses, and health monitoring devices. While high pressure and temperature sensitivity with visible indication are important for e‐skins, such multifunctionality often requires complex fabrication and integration processes, which hinders ...
