'This is the first system that combines all the pieces; efficient energy harvesting, energy storage, and the controlled brain stimulator.'

Researchers have devised an ingenious way to power deep brain simulators - Using the person's breathing movements.every year. Normally placed under the skin in the chest area with electrodes implanted in the brain, these stimulators are known to help with neurological and psychiatric diseases when traditional treatments fail.

University of Connecticut chemists Esraa Elsanadidy, Islam Mosa, James Rusling, and their team found a solution- they developed a deep brain stimulator that never needs its batteries changed.The device works in such a way that the movement of the user's chest is converted into electricity. As the person inhales and exhales, the chest wall is pressed on a small and thin electric generator called a triboelectric nanogenerator.

"We created our triboelectric nanogenerator using new nanomaterials which produce significant energy output when they come in contact with each other, enough energy to run the deep brain stimulator," Elsanadidy said in a statement."We wanted to make this fit in with the rest of the available technology in the usual way.
