Restore your eyesight with the help of the sun. Yes, blind people can now hope to get back their eye sight back with the help of a solar-powered chip. It stimulates retinal cells by spraying them with neurotransmitters.
Other implants under development apply an electric charge directly to retinal cells, heating them up. But, this device does not cause the cells to heat up. Not only that, it also uses very little power, and so forget about the need of external batteries.
The amazing solar-powered actuator flexes even as a very low intensity light strikes the retina. Called lead zirconate titanate, the solar cell is connected to a layer of piezoelectric material. And in response to the voltage, it changes shape pushing down on the silicon disc. This is a ground breaking application of solar energy in the field of medicine.
