Company Profile (Widetronix)

Widetronix logo
Widetronix is manufacturing small (mm), long life (+25 year) batteries for nano-watt to milli-watt applications in defense, medical, and logistics sectors, totaling $4B in addressable market. The underlying betavoltaic technology was created with over $2M Department of Defense (DoD) funding on Silicon Carbide (SiC) semiconductors in partnership with Cornell University. Widetronix is backed by $2M in state and federal grants, a $250K seed investment by Draper Fisher Jurvetson, and additional funding from customers. First product sales are anticipated in late 2010 to a defense contractor focused on anti-tamper circuits, followed by entry into the medical markets, specifically internal and external sensors, in 2011. The long-term strategy is to create a self-powered embedded sensor platform incorporating the betavoltaic battery, burst power (i.e., thin film, ultra-caps), and emerging low power micro-controllers. This robust monitoring platform supports applications in electrical generation and energy management.
