Strathclyde: Sunburn warning indicator

Licensing opportunity

Researchers at the University of Strathclyde in Scotland have developed an ultra violet light indicator, which could solve the problem of over exposure to sunlight rays.

The technology takes the form of an ink which can be printed onto a suitable substrate, for instance a strip of plastic to be worn around the wrist. Once UV light exposure goes above that recommended by the sunscreen, the indicator changes colour, thus alerting the wearer it is time to get out of the sun.

The product has a very low manufacturing cost, at less than one pence per unit. It can be stored indefinitely at room temperature, is easy to use, and allows text or logos to be printed on the wristbands.

Apart from working as a sunburn warning, the light indicator could be incorporated into packaging of UV sensitive materials or chemicals.

Patent protection is currently being secured by the University of Strathclyde. Demonstrators of the technology have been developed and contact is welcomed from organisations interested in developing, licensing or exploiting this technology.
