Wearable Kinematic Monitoring System Based on Piezocapacitive Sensors

International Conference on Wearable Micro and Nano Technologies for Personalised Health, 2019
Measuring the kinematics of human body movements is important for several biomedical and non-biomedical uses, such as rehabilitation, sports medicine, control of virtual reality systems, etc. This is typically performed employing accelerometers, electrogoniometers, electromagnetic sensors or cameras, which however are usually bulky, or can cause ...

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.

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.

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.

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.
