“…As a result, we are inclined to combine CP with organic polymers to form composite films, which could improve film uniformity on the one hand, and on the other, modify the surface of CP simply and regularly, so that the charge density can accumulate a higher initial value in a short time and have a larger stable current in the process of contact electrification, thereby providing an improvement scheme for the general low current of TENG. [47,48] A pair of polymers with very different polarities in the triboelectric series, PVDF and EC, was selected. PVDF lies at the bottom of the triboelectric series, which has excellent electron-accepting property, good flexibility, and outstanding film-forming ability, making it an almost ideal tribo-negative layer.…”

A friction layer with stability and durability is important to promote the practical application of triboelectric nanogenerators (TENGs). In this work, a two-dimensional cobalt coordination polymer (Co-CP) was successfully synthesized using cobalt nitrate, 4,4',4''-tricarboxyltriphenylamine and 2,2'-bipyridine. To clearly clarify the effect of the doping proportions of Co-CP and the types of composite polymers on the output performance of the TENG, Co-CP was combined with two organic polymers having different polarities (polyvinylidene fluoride (PVDF) and ethyl cellulose (EC))to form a series of composite films, which were used as the friction electrode materials to fabricate TENGs. Electrical characterizations indicated that a high output current and voltage were obtained from the TENG based on 15 wt.% Co-CP incorporated in PVDF (Co-CP@PVDF), which could be further improved by the Co-CP@EC composite film at the same doping ratio. Furthermore, the optimally fabricated TENG was demonstrated to prevent electrochemical corrosion of carbon steel.

“…Cu films were used as the positive triboelectric materials and electrodes, and PBAT+PLA films were used as the negative triboelectric materials. The use of biodegradable materials as triboelectric materials contributes to reducing environmental pollution, and the use of waste plastic bags as triboelectric materials contributes to a sustainable circular economy. , At present, PBAT + PLA is a widely used biodegradable plastic bag material . As shown in Figure S2, the waste PBAT + PLA film can be used as a triboelectric material without any complex fabrication process.…”

“…Most conventional power supplies are not applicable to bioresorbable electronics because they typically rely on nonbioresorbable materials that are also toxic. The materials outlined in section and others can be used to fabricate power supplies that are fully bioresorbable, with operating parameters that are useful for practical applications in temporary biomedical implants. ,− This section reviews recent advances in bioresorbable power supplies including batteries, supercapacitors, and mechanical, radio frequency, and photovoltaic energy harvesters. They all have their own advantages and disadvantages.…”

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