An Auto-Balancing Capacitance-to-Pulse-Width Converter for Capacitive Sensors [PDF]
IEEE Sensors Journal, 2021 A novel auto-balancing capacitance-to-pulse- width converter (CPC) that uses sinusoidal excitation, and operates in a closed-loop configuration, is presented in this paper. Unlike most of the existing CPCs, the proposed interface circuit is compatible with both single-element and differential capacitive sensors.

Reducing the capacitance of piezoelectric film sensors [PDF]
Review of Scientific Instruments, 2016 We present a novel design for large area, wideband, polymer piezoelectric sensor with low capacitance. The large area allows better spatial resolution in applications such as photoacoustic tomography and the reduced capacitance eases the design of fast transimpedance amplifiers. The metalized piezoelectric polymer thin film is segmented into N sections,

Multi-Channel Capacitive Sensor Arrays [PDF]
Sensors, 2016 In this paper, multi-channel capacitive sensor arrays based on microstrip band-stop filters are studied. The sensor arrays can be used to detect the proximity of objects at different positions and directions. Each capacitive sensing structure in the array is connected to an inductive element to form resonance at different frequencies.
