Аннотация:The unique properties present great prospects for polymeric ionic liquids (PILs) research in these areas, where progress and breakthrough technologies can be expected in the coming years. This brief review examines the latest work (2024–2025) and the prospects for using PILs as an effective component of sensor-related devices for medical or biological applications. Potentially, the PILs-based sensors can detect various movements in real time, which are necessary for high-performance wearable sensor platforms. The artificial electronic skin demonstrates high potential not only as a recording of body signals, but also as an effective wound dressing. The polymer actuators with PILs are indispensable in many applications.
