Improving the performance of piezoresistive force sensors by modeling sensor capacitance

2010 IEEE International Symposium on Industrial Electronics, 2010
Piezoresistive force sensors exhibit considerable lower accuracy compared with load cells and force measuring systems based in strain gauges, however a new method for measuring forces using piezoresistive sensors is described in this paper, leading to a considerable increase in the repeatability of force readings.

Micromechanical Capacitive Acceleration Sensor with Force Compensation

1990
A micromechanical acceleration sensor consisting of a differential capacitor has been developed. The seismic mass is etched in silicon forming simultaneously the middle electrode and is suspended on 8 cantilever beams consisting of highly boron doped silicon. The mass is embedded in a glass-siliconglass-sandwich between the counter electrodes which are

A prototype force sensing unit for a capacitive-type force-torque sensor

2014 IEEE/SICE International Symposium on System Integration, 2014
Force sensing is a crucial task for robots, especially when the end effectors such as fingers and hands need to interact with an unknown environment, for example in a humanoid robot. In order to sense such forces, a force/torque sensor is an essential component.

Multimodal Capacitive and Piezoresistive Sensor for Simultaneous Measurement of Multiple Forces

ACS Applied Materials & Interfaces, 2020
Quantitative information on the magnitudes and directions of multiple contacting forces is crucial for a wide range of applications including human-robot interaction, prosthetics, and bionic hands. Herein we report a highly stretchable sensor integrating capacitive and piezoresistive mechanisms that can simultaneously determine multiple forces.

A Structural Design and Decoupling Method of a Flexible Capacitive Pressure Sensor for Measuring Spatial Force

IEEE Sensors Journal, 2023
This article focuses on the spatial force decoupling method of specially designed flexible capacitive structures. In previous work, multidimensional force decoupling was mostly understood as decouple the force along the three reference axes of ${x}$ , $

Electrostatic forces and their effects on capacitive mechanical sensors

Sensors and Actuators A: Physical, 1996
Abstract This paper describes the electrostatic forces developed between the plates of capacitive mechanical sensors built in crystalline silicon and their effects on the measurement and the fabrication process. In single capaciti sensors the electrical forces can introduce offset errors in the measuring process, or can cause the collapse of the ...
