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 advisers is developed as a alternation of tiny solar cells. It is built-in abaft the retina and is a basic allotment of a arrangement that appearance a video camera, a abridged PC, acclimated to action the images captured by the camera, and a ablaze near-infrared LCD affectation congenital into video spectacles. “The pulsed 900-nanometer-wavelength angel that shines into the eyes is abundant to aftermath electricity in the chip,” the IEEE wrote.
The abstruse allotment of the new apparatus is rather sophisticated, but the abstraction is simple – solar-powered eyes for bodies who accept accelerating accident of photoreceptor beef on retina. It is account advertence that the latest apparatus will not accommodate a absolutely bright eyes – bodies will be able to admit faces and apprehend ample fonts at best. However, such advance is bigger than nothing. Currently there is no advice on back the accessory will be accessible
