Electronic Contact Lens Displays Pixels on the Eyes

A US and Finnish team is the first to build contact lens technology in an
electronic display, and also have tested it in vivo. The researchers placed
the technology into the eyes of rabbits, which suffered no ill effects. "This
verifies that antennas, radio chips, control circuitry, and micrometer-scale
light sources can be integrated into a contact lens and operated on live
eyes," says the University of Washington's Babak Praviz, who led the team.
Although the first version has only one pixel, a higher resolution lens
display is next on the team's agenda. Higher resolution lens displays could
one day be used as satellite navigation enhancers that show directional
arrows, or flash up texts and emails, and possibly video. In the shorter
term, the technology might provide people suffering from conditions such as
diabetes and glaucoma with a novel way to monitor their condition. The
current version of the contact lens display, powered by a remote
radio-frequency transmitter in free space, also has potential uses. "A
display with a single controllable pixel could be used in gaming, training,
or giving warnings to the hearing impaired," according to the researchers.
