Researchers demonstrated a novel technique to efficiently convert ambient low-power radiofrequency signals into DC power. This 'rectifier' technology can be easily integrated into energy harvesting ...
The market growth of low-power wireless devices particularly sensors is driving tremendous interest in using energy sources that can power the devices autonomously. The cost of running wires and the ...
This method has been refined over the years, and NIST reports that they can now calibrate transfer standards with an uncertainty of 0.67% [3][8] for 100 W measurements below 1 GHz. This uncertainty ...
