Abstract
A capacitive sensor for detecting the human heartbeat rate without direct contact with the skin is here described. The precordial movement changes the capacitance between the patch electrodes so modulating the frequency of an oscillator where the capacitance is inserted; as a consequence, the heartbeat signal can be obtained by demodulating the oscillating signal.
