Germany researchers presented a silicon artificial retina with 232 sensors. The 25-mm sq chip, made in a 350 nm process by Austriamicrosystems AG.

The researchers believe that patients who get the implant will have real visual reception, so people can walk around and see things…

Similar challenges on human hearing devices, cochlea has an estimated 20,000 sensors. In contrast, the popular implant is a device from Cochlear Ltd., Australia, used by 84,000 people, has only 22 sensors. The Cochlear implant use 4x DSPs and 3x 16-bit ADC. Engineers still have no success so far using that hardware to improve sound resolution…
