This solution features two applications: body touch sensing and automotive touch buttons. Powered by piezoelectric ceramic haptic feedback devices and automotive micro-impact sensors, it enables smart cabin interaction and exterior tactile perception. Haptic Feedback actuator works based on direct & inverse piezoelectric effects. Applied with driving voltage, the ceramic deforms mechanically to create vibration. Made of piezoelectric ceramic bonded to a metal substrate, it is stable, thin and compact for low-profile mounting. The automotive micro-impact sensor rapidly locates touch points and captures impact force, acceleration upon scratches or minor collisions. For visual blind spots, it sends valid sensing data to vehicle ECU to trigger responses like emergency braking and sentinel mode, preventing secondary damage.
