Soon you will no longer have to wonder if your food is still good. A smart sticker then shows whether a product can still be kept.
How does it work?
You stick a small gel sticker on the packaging of your food. Due to the unique composition of the sticker and a sensor, the color of the sticker changes to indicate whether the product is still good. The temperature is even taken into account.
For every product
Beijing University is currently testing the stickers on milk, but the intention is that they can be adapted to all kinds of other products in the future.
