A prototype smart label incorporating a novel printed electronic sensor for detecting the level of exposure to UV light has been produced by Acreo.
The Swedish developer will demonstrate the device at LOPEC in Munich on 27-28 May andBiosensors 2014 in Melbourne on 27-30 May.
UV detectorThe new UV light sensor is printed as part of a customisable plastic smart label package being developed by Acreo. The ink used is sensitive to UV light and generates a current proportionate to the amount of UV wavelength light that strikes it. This measurement is then supplied as an output on a basic flexible display on the label along with details of the total UV exposure since the label was fitted.
Water purification
A deal to develop the UV detecting label has already been signed between Acreo and a company specialising in water purification. Ultraviolet germicidal irradiation (UVGI) is a chemical-free method for killing bacteria in water for drinking or use in swimming pools.

Assuring a sample has received the appropriate dose of the shorter wavelength UV-C rays to destroy bacteria is an important element of any such system.
Healthcare and packaging
Other uses for the label will concentrate on ensuring people have not received too much UV light - a phenomena which can cause skin cancer and cataract damage. A skin-mounted version of the sensor label could be used on the beach or in a solarium (sun-bed). Acreo are actively pursuing partners to break into the health monitoring markets.

UV light can also degrade printed materials, plastics, chemicals and inks overtime. A monitoring label aimed at the packaging segment could thus be engaged to ensure a product arrives at its final destination in a suitable condition.
Platform
The smart label package which mounts the UV detector can be reconfigured to carry and display the read out of other sensors too. These can monitor the surface presence of glucose or bacteria and require printing with a different ink.

The hybrid device platform includes a silicon chip as well as the printed battery, sensor and display. It was developed as a collaborative project between Acreo and the local Linköping University.
