The devices are about the size of a credit card. Professor Krupenkin says the system is always powered. So unlike a traditional battery, this energy harvester never needs to be recharged.
The professor says he does not expect this invention to replace traditional batteries. But it will help reduce dependence on them. He says the technology would be useful for people in some rural areas where there is no electrical power. He expects to have a commercial product on the market within the next two years.
