MEA biochip retina tests. Researcher holding up an MEA (micro-electrode array) biochip (green) that is being used in tests on retina cells. The next generation of retinal implants, by around 2014, are expected to comprise 600 to 1000 electrodes. These retinal implants should enable improved vision for the blind compared to earlier implants that contained only 60 electrodes. This is an MEA biochip from Ayanda Biosystems. These biochips are also used to record and stimulate electrical activity in a range of other body tissues. Photographed in 2010 at the Institut de la Vision, Paris, France.
