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?

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.

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

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.

Is there any limitation to increasing its vibration range? Why only 14-155Hz vibrations? I guess that having the broader vibration range can have other usages.

What kind of industrial process control application ideas are in your mind?...remote sensing realated?

Note that a vibration sensor is a form of microphone. Note that in medical applications, we now face a future in which microphones are implanted into us. Note that the device can report wirelessly. Note the funding source, DARPA. Read the article on MondoNet (go to the home page for it) being developed as a distributed, wireless access fabric that will cover the world. (Note that the developers are concerned with "privacy".) So, let's see: everywhere you go, the government will be able to hear you. O brave new world!

This technology might also be a good way to power embedded structural integrity sensors in bridges or other systems which are difficult to access. Certainly vibration is available....

Rule to live by...Don't get sick, and apparently don't be near anyone that is if they have that technology implanted. Like all technologies, they can be used for good or evil and unfortunately the scale tends to tip towards evil far more today than ever before.

Yes! especially for earthquake-prone zones , the structural integrity can be monitored using a mesh of such sensors embedded into the structure.
