(Phys.org) -- Today, electronic touch pads are widely found on laptops, tablets, and other computing devices. Less common uses, but gaining in popularity, are book covers and food labels. These and other low-tech applications become possible as touch pads become extremely inexpensive, with applications ranging from beer bottle labels to disposable medical device labels. Now a team of researchers from the US and France have developed paper-based electronic touch pads that cost just 25 cents per square meter, a price at which touch pads can simply be thrown away when no longer needed.
