BetaBatt’s Modern Betavoltaic Cells to Power Active Implantable Devices

Nuclear energy cells that converted the impact of the β-particles on a p-n junction were developed in the 1970s.  One example was CCC’s atomic pacemaker, which was powered by a promethium-147  McDonell-Douglas Betacel 400.

Lately, BetaBatt Inc. of Houston, TX licensed beta-voltaic technology developed  at the University of Rochester to develop an implantable power source under the trade name DEC™ Cell, in which a silicon wafer captures electrons emitted by a radioactive gas such as tritium. The wafer is etched in a three-dimensional surface to capture more electrons.  The battery is sealed in a hermetic package  which  entirely  contains  the  low-energy  particles emitted by tritium, rendering the battery safe for long-term human  implant  from  a radiological-health standpoint.  Tri­tium has a half-life  of 12.3 years so that the technology  is more than adequate to meet the requirements of many implantable devices.

Although still in stealth mode, NanoStim Inc’s patents mention the use of a BetaBatt cell to power its wireless pacemakers.
