A team of scientists has perfected the first practical nanoscale power generator, capable of generating useable electrical current from a mere squeeze of your fingers. In the future it'll be able to draw power from your pulse.
The search for tiny power generator technology has slowly inched forward for years for good reason--there are a trillion medical and surveillance uses--not to mention countless consumer electronics applications-- for a system that could grab electrical power from something nearby that's moving even just a tiny bit. Imagine an implanted insulin pump, or a pacemaker that's powered by the throbbing of the heart or blood vessels nearby (and then imagine the pacemaker powering the heart, which is powered by the pacemaker, and so on and so on....) and you see how useful such a system could be.
The trick used by Dr. Zhong Lin Wang's team has been to utilize nanowires made...
