Abstract Polymer thermoelectric (TE) materials present a promising alternative to actuating low‐power wearable electronics without an additional power source, among which poly(3,4‐ethylenedioxythiophene) (PEDOT):poly(styrenesulfonate) (PSS) is candidate. However, it too hard and brittle integrate into wearables seamlessly comfortably. Herein, PEDOT:PSS‐based TE composites with simultaneous softness stretchability are fabricated by water‐borne polyurethane (WPU) PEDOT:PSS mixture containing the judiciously chosen ionic liquid (IL) subsequent drop casting. The obtained show stable voltage, high (>500%), ultra‐flexibility, excellent sensitivity (gauge factor = 1251). More importantly, exhibited “J‐shaped” stress–strain curves resembling human skins after loading/releasing treatment. skin‐like nonlinear elastic behavior combines enough in “toe” region, stretchability, strong strain hardening at late deformation stage, enabling its seamless comfortable integration body. Given desired mechanical performance strain‐sensing capability, composite designed serve as self‐powered sensor accuracy, suggesting potential motion detection. This work demonstrates versatility of developed electronics.
