Latest Invention: Solar-powered Device that Generates Energy for Electronic Contact Lenses

Researchers from Stanford managed to discover that the light that enters our eyes and helps us see can be also used to generate power for electronics implanted into eyes and electronic contact lenses. They found that near infrared light can serve as a source of energy and data signal for devices.

Their latest invention is an implant that is 3mm wide and 30 micrometers thick and which can be used to power electronic contact lenses and other eye implants.

According to IEEE Spectrum the implant developed by Stanford researchers is developed as a series of tiny solar cells. It is implanted behind the retina and is a component part of a system that features a video camera, a pocket PC, used to process the images captured by the camera, and a bright near-infrared LCD display incorporated into video spectacles. "The pulsed 900-nanometer-wavelength image that shines into the eyes is enough to produce electricity in the chip," the IEEE wrote.

The technical part of the new invention is rather sophisticated, but the idea is simple - solar-powered eyes for people who have progressive loss of photoreceptor cells on retina. It is worth mentioning that the latest invention will not provide a completely clear vision - people will be able to recognize faces and read large fonts at best. However, such improvement is better than nothing. Currently there is no information on when the device will be available

i beleive that people would be called part robot because of these. but it is good to have such a device like this, mostly for blind people.

This is brilliant work.
I believe that your innovations will give hope where hope was lost.
Other applications: anti depression eye mapping.
Security detection capabilities
improvements in learning learning
Guiding systems.
Please keep me in touch.

.."i dont think that is a great idea,how could that be that using one of our organ created as such invention may also contaminate or destroy our organ and the process of our vission of sight..some invention should not be approve"..

i wear contacts myself and i think how great is to see without glasses, but knowing that you can also generate some energy-that's just cool!!!
