abstract

Microbatteries are essential for portable electronics, cellular phones and MEMs devices to be miniaturized. Use of radioisotopes to realize nuclear microbatteries have been extensively researched. Electrical energy of a nuclear battery is produced from radioactive materials decaying by a suitable energy conversion process. Our approach in this paper is study of a direct collected charge to motion conversion. In this manuscript, the performance of radioisotope powered piezoelectric generator has been analyzed and simulated. The generator employs direct charging to convert radiated beta particles kinetic energy into stored electromechanical energy in a piezoelectric unimorph piezoelectricity to stored mechanical energy into extractable electrical energy.
