Achieving high-quality biopotential signal recordings requires soft and stable interfaces between tissues bioelectronic devices. Traditional bioelectronics, typically rigid dependent on medical tape or sutures, lead to mechanical mismatches inflammatory responses. Existing conducting polymer-based bioelectronics offer tissue-like softness but lack intrinsic adhesion, limiting their effectiveness in creating stable, conductive interfaces. Here, we present an intrinsically adhesive hydrogel with a modulus strong adhesion various substrates. Adhesive catechol groups are incorporated into the poly(3,4-ethylenedioxythiophene) (PEDOT) matrix, which reduces PEDOT size improves dispersity form percolating network excellent electrical conductivity strain insensitivity. This effectively bridges bioelectronics–tissue interface, ensuring pristine minimal interference from bodily movements. capability is demonstrated through comprehensive vivo experiments, including electromyography electrocardiography both static dynamic human skin electrocorticography moving rats. represents significant advancement for interfaces, facilitating more accurate less intrusive diagnostics.
