The battlefield envronment requires accurate and reliable detecton of electromagnetic field detection for militay personnel. This proposal describes the evaluation of electromagnetic detection devices, memory modules and transmitters and then developing the systems (miniaturize them) down to the level of incorporation onto an integated circuit (IC). This work proposal include the adaptation of microscopic batteries fabricated by cleanroom microfabricaton techniques already successfully demonstrated by the company. Microscopic batteries, together with photovoltaic devices, will be controlled byfuzzy logic and will provide the power required to render this devide completely autonomous. If needed, this power spply can be designed to have a multi-voltge capability, both for discharge and charge. This provides the opportunity to optimize performance in both the charge and discharge regimes.Small, autonomouns electromagnetic field detection will help protect personnel in the battlefield environment and a civilian version would help determine if there a high levels of electromagnetic radiation originating from cellular telephones.
