Staying alive in variable, intermittent, low-power environments (SAVVIE)
EPSRC Joint Research Grant: EP/K012908/1 & EP/K011979/1
This project researches how to design robust and reliable electronics for situations where there is a variable, unreliable source of energy. A number of situations, or states, have been defined, according to the level of depletion of on-board energy storage, and how variable the power supply is. In the most challenging states, for example where the input power is sporadic and spread over a wide range from nW to mW, modern electronics fails. We call this the “survival zone” and are investigating a combination of techniques from the areas of power electronics and asynchronous microelectronic design to allow devices to operate in this zone. Techniques include control circuits that are able to ride through variable voltages, the detection of states, and reconfigurable hardware resources and control algorithms to suit sporadic and sub-microwatt input power. The chief aim of this project is to produce survival zone design methods for the microelectronic design community.
