Triboelectric nanogenerators (TENGs) are electronic devices capable of harvesting low-frequency mechanical motions to produce electrical energy through the triboelectrification effect. A great number of electronic devices, such as wearable devices, implantable medical devices, and monitoring sensors, among others, use conventional power sources such as batteries and capacitors. They are usually toxic, nondegradable, and hard to recycle, representing human and environmental hazards. In addition, conventional batteries and capacitors are usually rigid, heavy, and not suitable for the fabrication of portable and flexible devices. TENGs appear as a promising option to be used in the development of light, portable, and self-powered electronic devices. TENGs were first developed using synthetic polymers such as polytetrafluoroethylene (PTFE), fluorinated ethylene propylene (FEP), polydimethylsiloxane (PDMS), and polyimide (Kapton) for the fabrication of the active surfaces that store charge. Bio-TENGs have been fabricated using biopolymers such as cellulose, silk, and chitosan. These Bio-TENGs take advantage of the inherent biodegradability and biocompatibility of biopolymers. In order to improve the capability of biopolymer-based surfaces to store electrostatic charge, several treatments are reported, including the incorporation of nanoparticles and surface treatments. These biopolymer-based active surfaces with improved properties allow Bio-TENGs to achieve output performances similar to those reported for synthetic TENGs. Bio-TENGs have been used in a wide range of applications, such as human monitoring systems, tissue engineering, electronic devices, and industrial-level flooring, among others. This review is focused on the development of Bio-TENGs. The different types of biopolymers used for the fabrication of active surfaces are described and classified as protein-based, polysaccharide-based, and synthetic-based biopolymers. The different strategies used for improving the triboelectric properties of biopolymer-based surfaces are presented, along with the resulting output performance of Bio-TENGs. The reported applications for these Bio-TENGs are also discussed.

The exploration of triboelectricity at the liquid–solid (L‐S) interface has sparked significant interest due to its potential for sustainable energy harvesting and technological advancement. Motivated by the need for innovative energy solutions and the unique advantages offered by liquid‐based environments, a comprehensive review of the fundamental concepts, mechanisms, and applications of liquid–solid triboelectric nanogenerators (TENGs) is provided. Three basic working modes of liquid–solid TENGs and the distinct properties and mechanisms of each model are discussed systematically. The physical fundamental of liquid–solid TENGs is further investigated, which includes “Wang Transition”, Wang's Hybrid Electric Double Layer model, tribovoltaic effect, equivalent circuit model, and the mechanisms of liquid–solid contact electrification based on density functional theory. Understanding charge transfer and charge distribution at the liquid–solid interface is also crucial to confirm the underlying mechanisms of liquid–solid TENGs. Finally, a broad range of applications of liquid–solid TENGs are explored, emphasizing their potential in addressing energy challenges and complex interdisciplinary issues that link the disciplines of materials science, chemistry, physics, and even electrical engineering.

Wearable therapy represents a research frontier where material science, electrical engineering, and medical disciplines intersect, offering significant potential for remote and portable healthcare. Unlike conventional approaches that rely on rigid materials, the ability to stretch is crucial for therapeutic devices to achieve enhanced mechanical adaptability. Moreover, the conformable integration of these devices into the body is pivotal in establishing reliable interfaces for long‐term treatment. These emerging devices provide an attractive platform for developing new therapeutic protocols that do not disrupt daily activities. This review comprehensively overviews recent progress in stretchable and body‐conformable electronics for wearable therapeutic applications. The discussion begins with the design and fabrication of these devices through structural designs and material innovation. The therapeutic mechanisms adopted by these devices are then systematically explored. Furthermore, the article delineates the crucial characteristics of wearable therapeutic devices, such as biocompatibility, secure skin attachment, and effective moisture management. This review article is poised to inspire innovative device designs and treatment protocols for future medical technology.
