Design and simulation of unimorph
piezoelectric energy harvesting system, in COMSOL Conference in Bangalore, 17-18 October 2013, Bangalore, India.
Piezoelectric fibers, a piezoceramic wafer or a piezoceramic unimorph
structure are mounted within the tire such that an electric charge is generated as the wheel assembly moves along a ground surface and is stored in energy storage devices.
Called Thunder (for thin-layer composite unimorph ferroelectric driver and sensor), the new technology is based on a piezoelectric ceramic wafer attached to a metal backing with a polyimide adhesive, according to Joycelyn Simpson, a materials research engineer in Langley's Composites and Polymers Branch.
Both unimorphs (thin wafers of ceramic bonded to single layers of metal) and bimorphs (metal shims sandwiched between ceramic layers) have shown promise.
