Low temperature deposition, by sputtering, on flexible/plastic substrates offers a relatively cheap alternative for fabricating single-/multilayer thin film devices. However, sputtering yields amorphous material, with low electrical conductivity, and requires subsequent annealing. Demonstrated is a new method of crystallisation, where controlled application of electrical pulses to sputter deposited...
A prototype energy-harvesting thermoelectric generator (TEG) is being designed, fabricated and tested to provide power for wireless sensors used in health monitoring of Navy ship machinery. TEGs utilize the heat transfer between shipboard waste heat sources and the ambient air to generate electricity directly and without any moving parts. In order to satisfy the required small design volume of 16...
