Store shelves that know when they need restocking are one of many potential applications for a novel sensing foam developed by researchers in Europe.
Shelves fitted with a thin layer of the foam can tell when products are out of stock, allowing a store to automatically monitor supply. And the foam could give other objects and surfaces sensing abilities, the researchers say.
The foam is made from flexible sheets of polyolefin, each a quarter of a millimetre thick and containing air gaps that make the material light and elastic.
