A very small value of inter-electrode capacitance is a main factor limiting image spatial
resolution of electrical capacitance tomography. The front-end sensing circuit of …

This paper presents a low-cost interface circuit for lossy capacitive sensors. Most of the
capacitive sensors are lossy in nature, where the resistance value of the sensor significantly …

Resistive sensors, with wide-span of operation, are used in a number of industrial scenarios.
In some of these cases, such resistive sensors may need to be located in a remote …

A non-interference AC voltage measurement system based on a resonant electric field
microsensor is proposed. The equivalent circuit of the proposed system is established …

This paper presents the design and development of a non-contact capacitive sensor suitable
to measure both angular and linear displacements. The sensor is composed of two parts: a …
