A planar capacitive force sensor with six degrees of freedom

Proceedings. 1986 IEEE International Conference on Robotics and Automation, 1986
The forces transmitted through any cross-section of a machine member such as a robot arm can be reduced to a single force and torque acting on any chosen point of the cross-section. The force and torque can be measured by a sensor that replaces the cross-section. A special feature of the sensor discussed here is that it is two dimensional, i.e. that it

MEMS capacitive force sensors for cellular and flight biomechanics

Biomedical Materials, 2007
Microelectromechanical systems (MEMS) are playing increasingly important roles in facilitating biological studies. They are capable of providing not only qualitative but also quantitative information on the cellular, sub-cellular and organism levels, which is instrumental to understanding the fundamental elements of biological systems.

Capacitive Force Sensor Fabricated in Additive Technology

2019 42nd International Spring Seminar on Electronics Technology (ISSE), 2019
In this paper a simple capacitive sensor for measuring force is presented. The sensor consists of three parts: the casing with the bottom electrode, the flexible central part and the upper plate with the electrode. An additive 3D printing technology with PLA and silver conductive ink are used for the fabrication of sensor.

MEMS Capacitive Force Sensor for Use in Microassembly

2008 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2008
This paper presents the design and modeling of a MEMS capacitive sensor for use in microassembly processes. Force monitoring is an important aspect in microassembly processes. It can be used to control the movement of the microgripper to properly engage with and release the micropart without physical damages due to excessive force.

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.

Development of Capacitive 6-Axis Force Sensor

IEEJ Transactions on Sensors and Micromachines, 2009
We have succeeded in developing a capacitive 6-axis force sensor that can singly detect 3-axis force and 3-axis moment. The capacitive 6-axis force sensor has an advantage of being able to realize high accuracy at low cost compared with conventional sensors using strain gauges. This paper details the sensor structure, detection principle, and detection

Development of a capacitive force sensor for artificial joint

2017 6th International Conference on Informatics, Electronics and Vision & 2017 7th International Symposium in Computational Medical and Health Technology (ICIEV-ISCMHT), 2017
Soft tissue tension is thought to have a great effect on the clinical performance of total joint replacement; such as shoulder, hip, knee, or ankle. However, there have been no reports quantifying these soft tissue tensions intraoperatively. For the shoulder, reverse total shoulder arthroplasty has been used in Japan since 2014.

Design of a High Sensitivity Capacitive Force Sensor

2007 7th IEEE Conference on Nanotechnology (IEEE NANO), 2007
This paper presents the design and development of a MEMS based, capacitive sensor for micro-force measurement. The sensor has an overall dimension of 3600 mum times 1000 mum times 10 mum and was fabricated using the Micragem fabrication process. A displacement reduction mechanism is incorporated in this sensor design to increase the sensitivity of the ...

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 ...

New design of micromachined capacitive force sensor

Journal of Micromechanics and Microengineering, 1993
Anisotropic etching of a (110) oriented silicon wafer has been used to realize a differential capacitive force sensor. This design is based on a simple concept allowing force to be measured in the plane of the sensor, giving a new and original product in the field of small force measurements.
