A contact lens that harvests radio waves to power an LED is paving the way for a new kind of display. The lens is a prototype of a device that could display information beamed from a mobile device.

Realising that display size is increasingly a constraint

This is the kind of breakthrough we need in order to make AR a practical technology for day to day use.

>One of the limitations of current head-up displays is their limited field of view. A contact lens display can have a much wider field of view. "Our hope is to create images that effectively float in front of the user perhaps 50 cm to 1 m away," says Parviz.

Just as exciting is proposed power source for the device:

>Parviz says that future versions will be able to harvest power from a user's cell phone, perhaps as it beams information to the lens. They will also have more pixels and an array of microlenses to focus the image so that it appears suspended in front of the wearer's eyes.

- One of the limitations of current head-up displays is their limited field of view. A contact lens display can have a much wider field of view. "Our hope is to create images that effectively float in front of the user perhaps 50 cm to 1 m away," says Parviz.
- One obvious problem is powering such a device. The circuitry requires 330 microwatts but doesn't need a battery. Instead, a loop antenna picks up power beamed from a nearby radio source. The team has tested the lens by fitting it to a rabbit.
