Research groups around the world are taking big strides towards developing ultrathin and flexible sensor devices that could be attached to the skin, or even organs, and monitor vital body functions. However, the adhesion to skin of many of these sensor patches is weak. A new milestone study on skin adhesives for wearable devices is about to change that. It demonstrates that it is possible to strongly and non-invasively attach soft wearable sensors and other devices to dry or wet skin.
