though I am a bit skeptical about the actual current capacity of the unit but the 3volt figure is definitely a big plus and should help in places which rely on very low power consumption or operate in 'burst mode'. At such places energy harvesters can serve to trickle charge the capacitors or small secondary cells. At a personal level I believe tht such devices are best used for 'in dark' operations for even the smallest dust covered solar cell will produce more usable electricity even from artificial light sources.

This is a wonderful concept. Just curious to know whether the same device can be applied to convert the street noise into electrical energy. Because, sound is also a form of vibration of the medium and with those thousand watt speakers blaring out in the processions and the car horns honking on the busy roads ( especially in India ) there is a lot of energy out there getting dissipated into the atmosphere.

This is very good news. I can imagine that energy harvesting will enable mobility and will be spread in to many of the products gaining more use like mobile phones and wireless headsets and the like. I think this can be very usefull in the car also as a lot of vibration happens there.

This is a clever idea. The higher voltage output is very helpful. If the stated mechanical-to-electrical efficiency number is very repeatable, this technique should find rapid adoption.

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
