Nanocrystalline core materials and circuits for energy harvesting
Abstract
Power and wiring are the Achilles# heels of contemporary IoT sensing solutions. The current state of the art in state estimation for complex engineered systems like warships includes mechanical sensors monitored #by hand# by human watchstanders, and coming #IoT# solutions that crust a ship with sensors and requirements for additional power wiring that become failure points and that produce a data glut; this proposed project adds value by producing a quantum jump in available power from in-situ energy harvesters. Specifically, we propose to explore and exploit new nanocrystalline magnetic core materials and associated power electronic harvesting circuits. These magnetic materials maintain high permeability even when #cut.# Cut or split-core harvesters can be easily installed without altering existing wiring and can provide unprecedented energy harvests for completely #wireless# installations that require no additional wiring for power or information transmission. The proposed technology will eliminate installation expense, removing wiring that, for example, becomes failure points on a ship. The technology has obvious #dual use# commercial application in any facilitywith critical maintenance and sensing needs for electromechanical systems. Approved for Public Release
