When sandwiched between polyurethane (PU) tape and applied to human skin, this material was able to detect both large-scale movements, such as those of the elbow, knee and fingers, and more subtle ones, including tiny movements of the muscles around the mouth and larynx during swallowing. It could even detect vibrations between two vocal cords, which could be useful for phonetic recognition. Furthermore, this hybrid hydrogel can be worn on a finger or metal stick and interact with electronic device touch screens, showing the potential to serve as electronic skin for robots and offering realistic skin functionalities. an electronic skin fingertip. The fingertip sensor is shown worn on a finger and attached to a metal stick for smartphone operations. Adapted with permission. Copyright 2021, Wiley-VCH.
