Flexible Capacitive Pressure Sensor with High Sensitivity and Wide Range Based on a Cheetah Leg Structure via 3D Printing.

ACS Applied Materials and Interfaces, 2023
Flexible pressure sensors can be used in human-computer interaction and wearable electronic devices, but one main challenge is to fabricate capacitive sensors with a wide pressure range and high sensitivity. Here, we designed a capacitive pressure sensor

Capacitive Pressure Sensor Modelling

2009 Second International Conference on Advances in Circuits, Electronics and Micro-electronics, 2009
The paper deals with an application theory of elasticity in the capacitive pressure sensor. A basis of this paper has been focused to the elastic part of the described model. This model has a second part which is used for solving of electric field and electric capacity.

Intraocular MEMS Capacitive Pressure Sensor

2021
Microelectromechanical system (MEMS) sensors are suitable for measuring intraocular pressure (IOP). IOP measurement is useful for monitoring diseases such as glaucoma. The average pressure range for healthy persons is within 10–20 mmHg. A pressure beyond this range could damage the eye nerves and causes of blindness.

Novel Capacitive Pressure Sensor

Journal of Microelectromechanical Systems, 2010
A new microelectromechanical-systems capacitive pressure sensor with extremely high sensitivity (2.24 ?F/kPa) is introduced. The sensor essentially consists of a small drop of mercury and a flat aluminum electrode that are separated by a 1 ?m-thick layer of Barium Strontium Titanate (a high dielectric-constant ceramic).

A Highly Sensitive Flexible Capacitive Pressure Sensor With Wide Detection Range Based on Bionic Gradient Microstructures

IEEE Sensors Journal, 2023
Introducing microstructures into a flexible pressure sensor is an effective way to improve performance of the sensor. However, existing methods for preparing microstructures in sensors, such as the artificial template method, not only are time consuming ...

Contamination insensitive differential capacitive pressure sensors

Proceedings IEEE Thirteenth Annual International Conference on Micro Electro Mechanical Systems (Cat. No.00CH36308), 2000
In this paper, a contamination-insensitive differential capacitive pressure sensor with a sealed gap is presented. This device is made of three polysilicon layers including a stationary middle plate and the top and bottom plates that are rigidly coupled together by a series of posts hence deflecting in tandem by a change in differential or gauge ...

Liquid Level Measurement through Capacitive Pressure Sensor

2020 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2020
Property of fluid and material compatibility limit the level sensor’s fabrication, dynamic range and accuracy. Piezoresistive pressure sensing elements with media compatible diaphragm are limited in low pressure dynamic. In contrast, capacitive pressure sensing elements provide better solution in terms of dynamic range.
