1. A system for generating physiological signals using a cloth capacitive sensor, comprising
at least a piece of cloth;
at least one conductive area arranged on the cloth
a signal circuit;
a capacitive sensor formed between the at least one conductive area and the skin of body, wherein the at least one conductive area is in direct contact with the skin of body;
and
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, in series or in parallel, with the cloth capacitive sensor to change a signal range of frequency, cycle, voltage or current;
wherein when a pressure, stretching force, torsion, or tensile force is applied between the body and the cloth, or when a dielectric constant between the body and the cloth changes, the capacitance changes, the signal circuit sends a signal that comprises the change in capacitance between the at least one conductive area arranged on the cloth and the body to the system;
wherein the change is represented by a frequency, cycle, voltage or current change, which is used to determine physiological change, posture change, medium change between the body and the cloth, gait analysis, and or at least one of the applied pressure, the stretching force, the torsion, or the tensile force.
