For the next‐generation wearable electronics, highly stretchable and deformable materials have received great attention. On the basis of the polymeric gelators [poly(methyl methacrylate‐ran‐butyl acrylate), PMMA‐r‐PBA] and ionic liquids (IL), nonvolatile, ultrastretchable and highly stable ionic sensory system is proposed. A systematically designed ion gel can be deformed and effectively dissipate applied strains due to the IL-insoluble components having low glass transition temperature (Tg). The resulting transparent ion gel was employed as the skin‐type strain sensor, referred to as ionoskin, by simply attaching to a part of the body (e.g., finger, elbow, knee, or ankle), and various human movements were successfully monitored. The ionoskin renders the opportunity to achieve wearable ubiquitous electronics such as healthcare devices and smart textile systems. |
