Patent ID: 8145298

Claim:
An electronic input device with piezoelectric sensor, comprising: a housing; a piezoelectric sensor comprising: a piezoelectric sensing layer provided on an outer surface of the housing; and a piezoelectric controlling/measuring circuit provided inside the housing and electrically connected to the piezoelectric sensing layer; a galvanic skin controlling circuit provided inside the housing; an electrode plate disposed on the piezoelectric sensing layer and electrically connected to the galvanic skin controlling circuit, wherein the piezoelectric sensing layer is disposed between the electrode plate and the housing; and a central processing circuit provided inside the housing and electrically connected to the piezoelectric controlling/measuring circuit and the galvanic skin controlling circuit, wherein when a skin portion is contacted with the electrode plate and the piezoelectric sensing layer, a galvanic skin signal of the skin portion is transferred to the galvanic skin controlling circuit by the electrode plate, a piezoelectric signal is transferred to the piezoelectric controlling/measuring circuit by the piezoelectric sensing layer, and the central processing circuit determines whether outputting the galvanic skin signal or not according to the piezoelectric signal.
