A Radionuclide Nanoencapsulation (RANA) Design Increases Electrical Current Generation
These RANA batteries carry out more efficient energy conversion than available betavoltaic batteries and their long lifespans allow them to power implantable medical devices, including pacemakers. Like other nuclear batteries, they include a radiation source that works with other materials to convert decay energy into an electric current. While the typical betavoltaic battery has a layered structure of alternating plates of radioisotopes, decay energy converters, and photovoltaic (PV) cells, these new batteries, developed by University of Florida researchers, do not require alternating sheets. The RANA batteries are conformable, easy to manufacture, and offer more efficient energy conversion, making them attractive components for biotechnology applications. The lifespan of an in vivo bioimplant fitted with a RANA battery can exceed one hundred years.
