Researchers at King Abdulla University of Science and Technology (KAUST) have developed a new electronic skin. The material is a composite of hydrogel and MXene, a metal-carbide hydrogel. This allows it to be stretched by more than 3,400 percent, self-heal, and adhere to skin. One additional ability, unlike other hydrogels, is that it can sense changes in a person's skin and convert them into energy. Applications include attaching the material to a patient's throat to convert speech into electronic signals, which could allow people with speech impairments to be heard clearly.
