A thermocouple can only generate power while there is a temperature differential. How do maintain one in a MEMS?

Nice improvement but 45uw at what cost? This should be scalable because a single layer generating X watts dont easily translate to double when the layers are doubled. I guess a super sensitive thermocouple in Si/Ge can beat this hands down in power output.

It is interesting (and counter-intuitive) that taking two facing cantilevers and connecting them (a bridge) results in more energy being extracted rather than less. I would have thought that the connection would reduce the freedom of movement and energy recovery. Does the connection allow a much heavier weight to be supported which thereby increases the energy extraction?

It is great to hear new technology being developed for energy harvester. With more energy being generated and yet lower cost, the deployment of WSN can become more practical. The only concern of the PZT kind of energy harvester is the reliability and robustness. Any data that can prove the part to be still useful after years of operation?

I think 2W/cubic cm is pretty good improvement on the power density of the PZT energy harvesting devices. Hope to see some more progress on this space. Is there any information available on the improved frequency bandwidth?

I bet they only need to generate RSS feeds. The point is they got good reputation/ credit and ppl are buying it.

I wonder who is MIT's PR company. They always manage to bring their research to the pages of trade magazines.

This is a very good information. The research of this is really in a good timing now that the Internet of things and the WSN (Wireless Sensor Networks) are becoming widespread. Mobile computing will benefit a lot from using this kind of technology. Imagine... in the near future devices will recharge at the same time they´re being used.
