UC San Diego engineers unveil ForceSticker, a wireless, battery-free sticker that could one day give robots the sense of touch. These electronic stickers are used to measure the force exerted by one object upon another, making them perfect for use in knee implants.
When used in knee implants, they would be able to measure the forces that implants exert on the joint. ForceStickers could also be placed on the bottom of warehouse packages to measure the weight of their contents, enabling one to quickly and accurately check inventory. Each sticker consists of two components: a rice grain-sized capacitor just a few millimeters thick and a radiofrequency identification (RFID) sticker, which functions like a barcode that can be read wirelessly using radio signals.

These force stickers could make technology more intelligent, interactive and intuitive. Humans, by nature, possess an inherent ability to sense force. This allows us to interact seamlessly with our surroundings and enables clinicians to perform delicate surgical procedures. Providing this force-sensing ability to electronic devices and medical implants could be a game-changer for many industries,” said Dinesh Bharadia, professor of electrical and computer engineering at the UC San Diego.
