Radioisotopes can be employed in microsystems in a variety of ways to exploit the many unique properties of radioactivity:1. The kinetic energy of the emitted radiation can be converted into electrical energy for micropower generation 2. The energetic charged particles emitted can be directly collected and charge-separation based electrostatic actuation of cantilevers can be enabled for autonomous sensors 3. The near constant probability of decay of nuclei could be utilized for realizing frequency standards.
