It can also be used as a sensor to detect vibrations in its range. As the energy it harvest is 10 times the conventional energy harvesters so it will be basically more sensitive.

I find from the picture that such a big inductor may not be necessary for 200 microwatts. Further the size and weight can be reduced

This sensor can be used to monitor the different types of machinaries mainly to monitor their performance. Example if the vibration seen is less the productivity is less and if the vibration monitored is more the wear and tear is more.This will be a call for maintance.This tiny system has good number of applications in the industrail process control areas.

This is a good news. The body implants working on self generated electrical energy for up to 20 years is something fantastic. This enables body implants to be fitted in the critical functions of the body without the need to change the battery . What could possibly be other application areas for such sensors?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
