“…reported a single electrode E‐TENG fabricated by using edible materials. [ 108 ] The rice sheet, edible silver leaf and Laver (Korean seaweed) serve the purpose of substrate, electrode and active layer, respectively, as depicted in Figure 22C. The device showed minimal effect on cell viability, as confirmed by the MTT assay, cell imaging and DAPI staining.…”

Triboelectric nanogenerators (TENGs) were first developed in 2012, and have become the desirable choice as energy harvesters in the research community worldwide. The popularity of TENGs is attributed to their low weight, low cost, high output, wide range of materials and device designs. TENGs have been explored for many applications including sensing, implantable power sources, healthcare, and biomedical applications. The performance of TENGs depends largely on the material since charge density (σ) is a material property. Moreover, 2D materials have been investigated as an alternative to the conventional metal electrodes. The dominance of polymers and metals in the traditional triboelectric series has lead researchers to explore novel materials to extend the applications and improve TENG output. This review article summarizes the progress in the development of frictional layers and electrode materials for TENGs. The mechanism for the output enhancement and device applications are discussed in detail. Finally, a perspective on the future and relevant challenges in material development for TENGs are discussed.

“…Since then, various piezoelectric materials have been demonstrated. Piezoelectric materials can be divided into the following two main categories: 1) inorganic materials, such as ZnO, [ 116 ] lead zirconate titanate (PZT), [ 117 ] barium titanate (BaTiO 3 ); [ 118 ] 2) organic materials, such as polyvinyl chloride (PVC), [ 119 ] poly(L‐lactic acid), [ 120 ] polyvinylidene fluoride (PVDF). [ 121,122 ] However, most inorganic piezoelectric materials with high performance are rigid and brittle, and they are very difficult to interface with soft biological organs and tissues.…”

The emerging field of implantable bioelectronics has attracted widespread attention in modern society because it can improve treatment outcomes, reduce healthcare costs, and lead to an improvement in the quality of life. However, their continuous operation is often limited by conventional bulky and rigid batteries with a limited lifespan, which must be surgically removed after completing their missions and/or replaced after being exhausted. Herein, this paper gives a comprehensive review of recent advances in nonconventional energy solutions for implantable bioelectronics, emphasizing the miniaturized, flexible, biocompatible, and biodegradable power devices. According to their source of energy, the promising alternative energy solutions are sorted into three main categories, including energy storage devices (batteries and supercapacitors), internal energy‐harvesting devices (including biofuel cells, piezoelectric/triboelectric energy harvesters, thermoelectric and biopotential power generators), and external wireless power transmission technologies (including inductive coupling/radiofrequency, ultrasound‐induced, and photovoltaic devices). Their fundamentals, materials strategies, structural design, output performances, animal experiments, and typical biomedical applications are also discussed. It is expected to offer complementary power sources to extend the battery lifetime of bioelectronics while acting as an independent power supply. Thereafter, the existing challenges and perspectives associated with these powering devices are also outlined, with a focus on implantable bioelectronics.
