Transient electronic systems represent an emerging class of technology that is defined by ability to fully or partially dissolve, disintegrate, otherwise disappear at controlled rates triggered times through engineered chemical physical processes after a required period operation. This review highlights recent advances in materials chemistry serve as the foundations for subclass transient electronics, bioresorbable characterized resorb (or, equivalently, absorb) biological environment. The primary use cases are designed insert into human body, provide sensing and/or therapeutic functions timeframes aligned with natural processes. Mechanisms bioresorption then harmlessly eliminate devices, and their associated load on risk patient, without need secondary removal surgeries. core content focuses enabling materials, spanning organic inorganic compounds hybrids composites, along mechanisms reaction environments. Following discussions highlight these components, sensors, power supplies, integrated diagnostic formed using specialized methods fabrication assembly. A concluding section summarizes opportunities future research.

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. Herein, we firstly systematically review recent developments in biodegradable materials, including bio-polymers, synthetic polymers, degradable inorganic materials composites. associated material synthesis methods device fabrication techniques summarized. Then, overview cutting-edge strategies realize high-performance devices. Subsequently, discuss encouraging implants, biosensing, energy harvesting, engineering, disease diagnosis treatment. Finally, future research directions, following clarification challenges mass-market proposed. This article comprehensively reviews piezoelectrics from optimization applications, with a focus on enormous potential transient

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. These include nonfluoropolymer piezoelectric polymers, triboelectric nanogenerators (TENGs), ferroelectric elastomers, flexoelectric polymers. A vision towards sustainable, non‐fluoropolymer‐based provided.
