Data input pen for Signature Verification

摘要: @ A pen (10) has a conductive casing (12) with an ink writing tip (21). The (21) is detachably mounted on the movable end of piezoelectric tube (26), which opposite (27) fixed to mounting in (12), so that cantilever fashion. (26) inner and outer tubular electrodes between electric signal generated according pressure during use. second (24), also fashion as have (25) (23), located behind different arrangement five for providing x, y signals transverse accelerations accelerometer are electrically processed by electronic circuitry (22) before leaving cable (8).
