A differential capacitance flowmeter [PDF]

open access: yesJournal of Physics E: Scientific Instruments, 1974
An accurate and robust flowmeter with no wearing components and a voltage output suitable for use with a potentiometric recorder, can be constructed around a mercury in glass manometer modified into a three electrode differential capacitance bridge.

The electrical double layer at the [BMIM][PF6] ionic liquid/electrode interface – Effect of temperature on the differential capacitance [PDF]

open access: yesJournal of Electroanalytical Chemistry, 2008
\u3cp\u3eImpedance spectra (50 kHz-1 Hz) were acquired and used to obtain the differential capacitance at the interfaces between 1-butyl-3-methylimidazolium hexafluorophosphate, [BMIM][PF6] ionic liquid and three different electrode materials (Hg, Pt ...

CMOS interface for differential capacitive transducers

Proceedings of the 2005 European Conference on Circuit Theory and Design, 2005., 2006
A high-performance and simple CMOS interface circuit for differential-capacitance transducers is presented and its main performance is evaluated. The solution is based on a capacitance to current conversion that allows low-voltage operation, while providing both high speed and accuracy.

A novel interface architecture for differential capacitive sensors

2023 9th International Workshop on Advances in Sensors and Interfaces (IWASI), 2023
In this work, we propose an analog fully differential interface for capacitive sensors. The working principle of the proposed solution is based on an autobalancing bridge topology entirely formed by capacitive components. In particular, two capacitors form the sensor, while other components are voltage-controlled capacitors (VCCs) which in steady-state
