Useful with regulation?
mithrandir   5/9/2014 1:06:00 AM
Wonder what sort of regulation this little guy needs before it's useful to be plugged in. I don't particlarly imagine watchmakers jumping at the prospect of adding a regulator IC on the already small footprint.

What about hot air?

I believe some people may generate enough hot air in order to power this generator!!

Not useable in practice - I think.

Hello, does not work in temperate climates where the temp difference is small and heat transfer away from the 'generator' is not a sure thing. And as a Norwegian I know it's not going to work in winter. I'm not going to bare my wrists! Thus the temperature inside my jacket and mittens cafrefully covering my wrists is the same as my external body temperature ie no energy can be harvested. A lot more work is needed.

However, if someone comes up wirt a safe and efficient way to move energy from the shoes to the wrist (apart from wires or using the body's blood stream) then we start talking re how to power a werable device!

Re: Use in wearables
Pablo Valerio   5/8/2014 11:20:08 AM
I believe this technology needs further development. The initial numbers are very encouraging, but it can be enhanced.

Also people do not use the wearables all the time, so continous charging is not necessary, but the power strip can provide addtional usage time.

Use in wearables
fpga_brad1   5/7/2014 8:39:36 PM
Assuming 15C delta temp(pretty high for typical users) and 140mAh battery that lasts a day I calculate it would take roughly 46  cm2 to power it. That is about one order of magnitude too large for typical wearables. It is nice work but 46 cmworth of solar cell will also power this in an office environment. If you get an athlete in a cold environment the numbers do start to look reasonable. Parts Search

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
