Power Solutions for Integrated Anti-Tamper Technologies
Widetronix is commercializing betavoltaic batteries that produce nA to uA"s of current continuously for 3 to 100 years. In addition to meeting desired AT operational lifetimes (>25 years), these continuous power generators have high energy density potential enabling integration with ultra low-power microelectronics. In this proposed Phase II effort, Widetronix will demonstrate integration of Cornell"s ultra-low power micro-controller (SNAP) powered by a Widetronix 2 uW betavoltaic device. The phase II scope of work focuses on the following areas facilitate integration of these technologies: Isotope Develop isotope supply chain that maximizes power output and stability and provides a scalable pathway to volume manufacturing. Semiconductor optimize betavoltaic to specific isotopes by developing advanced modeling and testing protocols leading to a high volume manufacturing process. Packaging Develop MILSPEC packaging strategies that minimizes footprint while enabling integration of betavoltaic and SNAP microprocessor. Integration demonstrate betavoltaic device & SNAP processor on common printed circuit board with inputs for AT sensor with programmed AT functionality. This Phase II effort will result in a fully MILSPEC certified product enabling autonomous intelligence for AT sensors. First sales are anticipated in 2011 to defense contractors and 2013 in commercial sectors.
