An activator has a base on which is mounted an elastically deformable micromechanical element that has a section that is free to be displaced toward the base. An absorber of radioactively emitted particles is formed on the base or the displaceable section of the deformable element and a source is formed on the other of the displaceable section or the base facing the absorber across a small gap. The radioactive source emits charged particles such as electrons, resulting in a buildup of charge on the absorber, drawing the absorber and source together and storing mechanical energy as the deformable element is bent. When the force between the absorber and the source is sufficient to bring the absorber into effective electrical contact with the source, discharge of the charge between the source and absorber allows the deformable element to spring back, releasing the mechanical energy stored in the element. An electrical generator such as a piezoelectric transducer may be secured to the deformable element to convert the released mechanical energy to electrical energy that can be used to provide power to electronic circuits.

1. An activator 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) an absorber of radioactively emitted particles formed on one of the displaceable section of the deformable element and the base; and (d) 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.
