Patent ID: 7301254

Claim:
A power generator comprising: (a) a base; (b) an elastically deformable element having a section spaced from the base that is free to be displaced toward the base from an initial position by elastic deformation of the deformable element; (c) a first electrical generator coupled to the deformable element for developing an electrical potential across output terminals of the generator as the deformable element returns elastically to its initial position; (d) an absorber of radioactively emitted particles formed on one of the displaceable section of the deformable element and the base; (e) a material comprising a radioactive source formed on the other of the displaceable section of the deformable element and the base that faces the absorber across a gap, the radioactive source radioactively emitting charged particles, the deformable element capable of displacing in response to accumulated charge on the absorber such that at a sufficient charge the absorber effectively electrically contacts the source to discharge the absorber and allow the deformable element to return elastically to its initial position; and (f) A second electrical generator comprising a betavoltaic cell carried on the deformable element to provide a direct current (DC) electrical potential that can be added to the first electrical generator's electrical potential, such that there is a continuous power output that can be used to provide power to electronic circuits.
