A team of Finnish and US bio-engineers have found a way to place an antenna, radio receiver, control circuitry, and an LED into a contact lens. While many of us have dreamed of the day an interactive lens would become available, the lens is currently only being tested on rabbits at the University of Washington, Seattle.
The research team, led by Babak Praviz, has managed to display a single, remote-controlled pixel on a contact lens. Power is then transmitted via radio frequency to the antenna (which is the gold ring around the image above). The circuit then uses the energy to power the LED which transmits a blue light.
Since this is the first baby-step of a new technology that will undergo numerous transformations, there are some minor imperfections in the lens’ current form. For example: due to the tiny nature of the antenna, a power source has to be within 10cm for it to function properly. But it shouldn’t take long for the research teams to figure out a way around this.
The research team is already looking into adding more pixels to the lens to advance its capabilities, and luckily, no bunny rabbits were harmed in the testing of this lens.
