Journal ArticleDOI
A time domain bridge-based impedance measurement technique for wide-range lossy capacitive sensors
TL;DR: In this article, a simple and accurate impedance measurement technique (IMT) for wide range lossy capacitive sensor is proposed, which is based on the separation of in-phase and quadrature components.
Proceedings ArticleDOI
Respiration Monitoring Using a Flexible Paper-Based Capacitive Sensor
TL;DR: This study proposes a low-cost capacitive sensor fabricated using screen printing of carbon paste interdigitated electrodes on paper substrate for respiration monitoring, and shows better response time compared to resistive configuration.
Journal ArticleDOI

Meraj Ahmad,Shahid Malik,Sourya Dewan,A. K. Bose,Dinesh Maddipatla,Binu B. Narakathu,Massood Z. Atashbar,Maryam Shojaei Baghini +7 more
TL;DR: A half-bridge-based versatile, four-phase auto-calibration-based differential and ratiometric operation is used to compensate for the baseline resistance of the sensor and the mismatches due to the non-ideal circuit parameters.
Journal ArticleDOI
Impedance-to-Time Converter Circuit for Leaky Capacitive Sensors With Small Offset Capacitance
TL;DR: An accurate impedance-to-time converter (ITC) circuit for leaky capacitive sensors that is able to deal with these problems and estimate the sensor capacitor and leaky resistor is presented in this article.
Journal ArticleDOI
AN-C2V: An Auto-Nulling Bridge-Based Signal Conditioning Circuit for Leaky Capacitive Sensors
TL;DR: In this paper, a fully analog auto-nulling bridge based capacitance-to-voltage (AN-C2V) converter circuit is presented for measuring the capacitive component of the leaky capacitive sensors.
