Method and system for generating physiological signals with fabric capacitive sensors

Abstract

A system for generating physiological signals using a cloth capacitive sensor, includes a cloth, at least one conductive area arranged on the cloth, a signal circuit; a capacitive sensor formed between the cloth and a human body; a resistor R, a capacitor C, an inductor L, an operational amplifier, a diode, a Schmitt trigger, CMOS, a transistor, or an IC that forms a charge or discharge circuit, connected with the cloth capacitive sensor to change a signal range of frequency, cycle, voltage or current; wherein when a force, pressure, tensile force, torsion or tension is applied between the human body and the cloth, the capacitance changes, the circuit sends a signal, and the system receives the change in capacitance between the conductive cloth and the human body; wherein the change is represented by a frequency, cycle, voltage or current change.
