Disclosed is a device for generating an analog output signal indicative of an impact to a transducer. The transducer may be mounted on protective equipment utilized in various martial arts fields, such as protective vests and the like or can be mounted on training equipment, such as a heavy bag, striking pad, etc. In a preferred embodiment the transducer is a piezoelectrical signal which is indicative of the amount of deformation. By placing the piezoelectric film on top of a deformable material, in a preferred embodiment sandwiching it in the deformable material, impacts to the deformable material will strain the piezoelectric film generating the signal output. In a further embodiment of the present invention, the piezoelectric transducer is mounted on a target pad and provides an analog output indicative of the characteristics of an object impacting the target pad. For use in the martial arts, the transducer may be connected to a transmitter and remote receiver for providing an indication of the impact at a remote location.
