Highly Sensitive Piezocapacitive Sensor for Detecting Static and Dynamic Pressure Using Ion-Gel Thin Films and Conductive Elastomeric Composites

ACS Applied Materials & Interfaces, 2017
A new class of simple and highly sensitive piezocapacitive sensors that are capable of detecting static and dynamic pressure changes is reported. The pressure sensor structure is formed by vertically sandwiching a sandpaper-molded carbon nanotube/poly(dimethylsiloxane) composite (CPC) dielectric layer between two ion-gel thin film electrodes.

Piezocapacitive effect of a sandwich structure in a microfabricated cantilever

2010 IEEE 23rd International Conference on Micro Electro Mechanical Systems (MEMS), 2010
This paper gives insight into the origin of the piezocapacitive effect of a sandwich structure (metal-dielectric-heavily doped silicon) in a microfabricated cantilever. It implies that the mechanical stress changes both the sizes of the capacitor and the dielectric constant of the dielectric.
