DARPA seeks to transform the energy efficiency of unattended sensors through elimination or substantial reduction of the stand-by power consumed by the sensors while they await a signature of interest. The improved energy efficiency is expected to result in an increase in the sensor mission lifetime from months to years. The Near Zero Power RF and Sensor Operations (N-ZERO) program aims to create intelligent sensors that can process and detect RF and physical sensor signatures, consume less than 10 nW of power, and attain a low false alarm rate of 1 per hour or better in an urban environment. See the full DARPA-BAA-15-14 document attached.
