“…Biodegradability can allow the entire device to be completely or partially degraded by water and soil in the environment, or it can be degraded by pH, light, heat, bacteria, and solvents. This characteristic can reduce the energy sources that produce harmful substances for the environment and organisms and also minimize the cost and risk of recycling electronic waste [82]. Wang et al developed a self-powered electronic skin based on all-nanofiber TENG using polylactic acid glycolic acid (PLGA) and polyvinyl alcohol (PVA).…”

Human skin, the body’s largest organ, plays a crucial role in perceiving mechanical stimulation and facilitating interaction with the external environment. Leveraging the unique attributes of human skin, electronic skin technology aimed at replicating and surpassing the capabilities of natural skin holds significant promise across various domains, including medical care, motion tracking, and intelligent robotics. In recent research, triboelectric nanogenerators have emerged as a compelling solution for addressing the energy challenge in electronic skins. Triboelectric nanogenerators harness the combination of the triboelectric effect and electrostatic induction to efficiently convert mechanical energy into electrical power, serving as self-powered sensors for electronic skins, which possess the advantages of self-powered operation, cost-effectiveness, and compatibility with a wide range of materials. This review provides an introduction to the working principles and the four operational modes of triboelectric nanogenerators, highlighting the functional features of electronic skins, such as stretchability, self-healing, and degradability. The primary focus is on the current applications of self-powered electronic skins based on triboelectric nanogenerators in medical care, motion tracking, and machine tactile recognition. This review concludes by discussing the anticipated challenges in the future development of self-powered electronic skins based on triboelectric nanogenerators. This review holds practical significance for advancing the practical use of self-powered electronic skins based on triboelectric nanogenerators and offers valuable guidance for individuals interested in pursuing scientific and healthy endeavors.

“…Despite being hydrophobic polymers, polyethylene (PE) and polypropylene (PP) films can nonetheless show changes in triboelectric characteristics with changes in the humidity levels. 62 These materials are frequently utilized in the triboelectric layers of humidity sensors. A substance called cellulose acetate is hydrophilic, meaning that it may absorb moisture and have variable triboelectric characteristics.…”

“…Although degradable CS-based TENGs have been widely explored for environment-friendly smart sensor applications, improving their output − and mechanical properties remain a challenge. , Some researchers have found that adding plasticizers can simultaneously increase the tensile properties of the polymer friction layer and output properties of TENG. − Park et al used polyvinyl chloride (PVC) and adipate-based plasticizers to fabricate a single-layer, stretchable, attachable material based on a plasticized PVC gel and used it for tactile sensing. The plasticizers improved the transparency and stretchability while providing a considerably higher dielectric constant (90–300 times higher than pure PVC).…”

Chitosan (CS), as the polymer friction layer of triboelectric nanogenerators (TENGs), has great potential for application in the development of degradable wearable sensors. However, its mechanical properties and output performance require further improvement. Although introducing plasticizers into polymers can simultaneously increase their mechanical properties and TENG output, this strategy remains unexplored for degradable polymer TENGs, which exhibit great potential as green materials in electromechanical conversion. Herein, we used glycerol and polyethylene glycol as plasticizers to enhance tensile properties and output properties of the CS TENG. Plasticizer incorporation resulted in an improved surface roughness and the introduction of numerous −OH groups, thereby improving the tribo-positive electrical generation of CS. The maximum open−circuit voltage can reach 173 V, which was three times higher than that of pure CS-based TENGs. Moreover, reduced Young's modulus of this film made it more advantageous for flexible sensor applications, and throat sensing and handwriting recognition were realized. Finally, the CS sensor exhibited antibacterial activity and complete degradability in soil within 36 days. Overall, this plasticizing method is expected to be extensively studied in the field of degradable, wearable polymer TENG sensors.
