UK-based beverage company SABMiller has launched a new smart sensor that shows the 'perfect' drinking temperature of beer.
Based on a colour-changing ink concept, the sensor is enclosed in a pack that accurately displays the beer's temperature after a button is pushed.
The development is the result of a partnership between SABMiller and Germany-based Fraunhofer Institute.
The ink remains transparent at ambient temperatures and turns blue when the beer reaches the desired drinking temperature.
SABMiller global packaging manager and sensor technology creator Doug Hutt said: "The colour changing ink resonated well with consumers.
"The new smart sensor display system has taken five years to develop and is based around cutting-edge printed electronics (PE) technology, which allow the sensor, display and battery to be seamlessly integrated within packaging."
SABMiller has patented the technology and expects to demonstrate its potential within the branded consumer goods sector over the next decade.
