Patent ID: 8860553

Claim:
A self-powered device, comprising: a radioisotope-powered current impulse generator including a spring assembly comprising a cantilever having at least one fixed end attached to a base and a reciprocal region, further including a radioactive particle emitter; a piezoelectric-surface acoustic wave (P-SAW) structure including an input port electrically connected in parallel to the current impulse generator and an output port; a radioactive particle receiver that is attached to one of the reciprocal region of the cantilever and the spring assembly at an opposing distance above or below the reciprocal region of the cantilever, characterized by an operable distance between the radioactive particle emitter and the radioactive particle receiver that is a maximum distance and the interdigitated electrodes of the input port have a maximum number of electrode fingers, wherein each of the input port and the output port include a plurality of interdigitated electrodes.
