| description | Abstract The rapid advancement of wearable technology has led to the growing significance of flexible sensors in medical health monitoring and motion tracking. Traditional electronic skin frequently experiences unstable sensing performance attributed to inadequate interface compatibility and uneven distribution of conductive materials. Ionic skin presents an innovative method for acquiring biological signals via ion migration; however, its biocompatibility concerns restrict its broader use. This study introduces an eco‐friendly and efficient synthetic method for the preparation of conductive elastomers utilizing deep eutectic solvents (DES) and polyvinyl alcohol (PVA). The resulting composite polymer network structure demonstrates a balance between elevated mechanical strength and high conductivity. The resultant material exhibits an electrical conductivity of 4.4 × 10⁻¹ S m⁻¹ and a tensile strain of 1200%. The attributes of this elastomer allow pressure sensors to demonstrate exceptional performance, featuring a sensitivity of 0.21 kPa⁻¹ and a wide detection range of 0–200 kPa. This research presents a novel approach for the development of high‐performance flexible sensing materials, which hold considerable application potential in areas including healthcare and motion detection. |
