Abstract The reliable function in vivo of self‐powered implantable bioelectric devices (iBEDs) requires biocompatible, seamless, effective interactions with biological tissues. Herein, an tissue‐adhesive piezoelectric soft sensor (TPSS), which the converts biomechanical signals into electrical signals, and adhesive hydrogel (AH) strengthens this conversion by seamlessly adhering on wet curvilinear surface, is proposed. optimized AH exhibits strong adhesion to various organic or inorganic surfaces, including six commonly used engineering materials three As a pressure sensor, TPSS proves good vitro performance high output 8.3 V, long‐term stability over 6000 cycles, energy power density 186.9 µW m −2 . In large animal experiment, adheres right‐side internal carotid artery Yorkshire pig monitor blood during surgical operation. Compared commercial sensors that work inserting tissues, does not cause any damage can be peeled off after service. integration enables more efficient between system iBEDs, also contributes next‐generation bioelectronics features battery‐free, intelligent, accurate.

Piezoelectric devices integrated into physiological systems can be used effectively for biomedical applications such as sensing biological forces, self-powering devices, stimulating tissue regeneration and healing, diagnosing medical problems. The limitation of current well-established implantable piezoelectric is that most them are non-degradable require extra removal surgery. Biodegradable implants avoid the above dilemma by degrading inside body after fulfilling their service life, therefore promising to become next-generation implants.

Abstract Fluoropolymers, including polytetrafluoroethylene (PTFE, Teflon), polyvinylidene difluoride (PVDF), and fluorine kautschuk materials (FKMs, Viton) are critical polymers for applications ranging from non‐stick coatings, corrosion resistant seals, semiconductor manufacturing, membranes, energy harvesting technologies. However, the synthesis of these fluoropolymers requires use per‐ polyfluorinated alkyl substances (PFAS) known colloquially as “forever chemicals,” such there is a pressing need to develop alternative technologies that can serve end‐use without environmental cost using PFAS. Further, themselves fall under PFAS umbrella. Here, mechanical‐to‐electrical reviewed benchmarked against leading fluoropolymer harvesters.
