Figure Lengend Snippet: Wearable and epidermal electrode systems. a) Chemical structure of P(BA‐co‐MAA) ionogel and distribution of hydrogen bonding strengths. As the frequency decreases, physical interactions progressively dissociate, resulting in simultaneous interchain breakup and enhanced entanglement that serve as topological crosslinks.
