Bicycle lights you wear under your skin

An international team of scientists has developed ultra-thin sheets of inorganic light-emitting diodes (LEDs) for implantation under the skin for biomedical applications, reports PhysOrg.com this week.

The technology could pave the way for bicycle lights worn under the skin.

Light-emitting ‘tattoos’

The LEDs are tiny in size and are designed to monitor wound healing or to control the delivery of drugs triggered by light in photodynamic drug therapy, but on a larger scale, ‘light-emitting tattoos’ could ensure cyclists were always equipped for cycling after dark.

Cycle lights future tech?

A spokesperson for the ETA said: “Having under-the-skin lights fitted to one’s hand or calves sounds horrific today, but might one day be regarded as no more radical than a tattoo.”

Cycle insurance from the ETA includes, amongst other things, new-for-old, third party cover, personal accident cover, race event cover and if you suffer a mechanical breakdown, they will come out and recover you and your bike.
