A battery-free tag for wireless monitoring of heart sounds
We have developed a wearable, battery-free tag that monitors heart sounds. The tag powers up by harvesting ambient RF energy, and contains a low-power integrated circuit, an antenna and up to four microphones. The chip, which consumes only 1.0 uW of power, generates digital events when the outputs o...
