Abstract
Radioisotope thin films, with their 1-100 MJ/cc energy densities and 1-100 year half lifetimes, are suitable for powering long lifetime autonomous microsystems. In this paper, we review the application of nickel-63 radioisotope thin-film fuels in long lifetime power generators, direct charging DC voltage generators, novel low voltage drop bridge rectifiers, and self-powered wake-up sensors. A broad tool kit of capabilities enabled by the energetic thin films may enable near-perpetual microsystems.
