Multifunctional flexible sensors are the development

trend of wearable electronic devices in the future. As the core of

flexible sensors, the key is to construct a stable multifunctional

integrated conductive elastomer. Here, ionic conductive elastomers

(ICEs) with self-wrinkling microstructures are designed and

prepared by in situ phase separation induced by a one-step

polymerization reaction. The ICEs are composed of ionic liquids as

ionic conductors doped into liquid crystal elastomers. The doped

ionic liquids cluster into small droplets and in situ induce the

formation of wrinkle structures on the upper surface of the films.

The prepared ICEs exhibit mechanochromism, conductivity, large

tensile strain, low hysteresis, high cycle stability, and sensitivity

during the tension-release process, which achieve dual-mode

outputs of optical and electrical signals for information transmission and sensors.
