Ionically conductive gels provide low interfacial impedance through fluidic wetting but suffer from dehydration and instability, whereas dry soft electrodes offer mechanical stability but lack the rheological adaptability needed for intimate skin contact. Here, we report a state\u2010programmable graft interpenetrating network (g\u2010IPN) that enables a printable and reactivatable conductive adhesive (RCA). The RCA simultaneously achieves high electrical conductivity, state\u2010dependent adhesion, and reversible viscoelasticity. By transitioning from a mechanically robust solid film to a fluidic state via solvent activation, the RCA infiltrates complex skin surfaces and hair\u2010occluded regions, delivering lower interfacial impedance than traditional gels. These properties enable stable electroencephalogram (EEG) and pulse recordings across both rigid and soft electrode platforms, establishing a scalable strategy for high\u2010fidelity epidermal bioelectronic interfaces.<\/jats:p>","DOI":"10.1002\/smll.75442","type":"journal-article","created":{"date-parts":[[2026,8,26]],"date-time":"2026-08-26T07:39:48Z","timestamp":1787729988000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["State\u2010Programmable
