The rapid expansion of soft electronics and actuators necessitates the development of mechanically robust substrates possessing a unique combination of properties: high stretchability, self-healing capabilities, and favorable dielectric characteristics. This study presents a novel composite film comprising an elastic Styrene-Ethylene-Butylene-Styrene (SEBS) matrix and a high dielectric constant Polyvinylidene Fluoride (PVDF) component. A systematic investigation of its mechanical characteristics reveals exceptional stretchability, with a strain of up to 1600%, and showcases remarkable self-healing properties, which manifest upon exposure to a moderate temperature of 70 ᕑ. The incorporation of SEBS not only imparts mechanical resilience but also contributes to the stabilization of dielectric properties across a wide range of frequencies while the incorporation of PVDF contributes the increase of the output voltages upon pressure. The versatility of this material system holds potential for addressing a wide array of challenges in soft electronics, from conformable wearable technologies to adaptable robotic interfaces.
