Custom, Battery-Free BSN Platform

Body sensor networks (BSNs) are rapidly becoming important tools in today's health care. The goal of the ultra low power BSN project is to develop a system-on-chip (SoC) operating in the sub-threshold regime to increase processing efficiency and life time of BSN nodes. Increased life time of these devices will result in reduced cost to consumer and less invasive procedures to replace batteries/nodes. Work is on-going, looking into optimizing the processor, adding accelerators, and energy harvesting.
