An intrinsic transduction system for stimulating portions of the body. The output of the transducer is a stimulating and/or nerve regenerating frequency having components falling within predetermined frequency band limits so as to optimally excite touch nerve fibers relative to nociceptor or pain receptor nerve fibers. Products, in particular a prosthetic disc, shoe, apparel, a spark cleat, incorporating an impact sensing element made from polymeric piezoelectric material. In response to impact, the piezoelectric material generates an electrical signal to a battery powered negative ion emitting unit or to an information display device which is at least partially molded into or contained in the product, or relayed by antenna. In addition, a CPU can be included in the circuitry to provide preprogrammed control of the emitting devices or to evaluate the input from the impact sensing element and a negative ion transducer, permits ready control of a quantity of generated negative ions and resists a size and thickness reduction. The negative ion transducer is of an electron emission type in which electrons are emitted by spin oscillation and/or impressing a negative ion voltage electric discharge . A negative ion transistor chip is used for amplifying a voltage from a capacitor and circuit.
