Abstract The field of soft wearable bioelectronics requires materials that are flexible, stretchable, biocompatible, and capable being used over long durations. Although polydimethylsiloxane (PDMS) is one the most commonly substrates for these devices due to its biomimetic properties compared biological tissues, intrinsic hydrophobicity causes it underperform in environments. In this work, a hydrophilic, stretchable PDMS electrospun fibrous mat developed overcome limitation by incorporating amphiphilic polymer polyethylene glycol block copolymer (PEG‐BCP) into porous matrix. nonwoven hydrophilic silicone shows apparent improvement stable hydrophilicity, indicated significant decrease water contact angle (from 125° 51°) 7 days, along with improved cellular adhesion enhanced breathability. PDMS‐PEG fibers show higher cell proliferation than unmodified fibers, suggesting potential long‐term applications. also maintains structural integrity under mechanical stress, demonstrated stretchability up 308.8% strain reduced forces. This novel material surpasses previous enables electroless gold plating, providing promising future electronics biomedical featuring conductive, biointegrated materials.
