With the advent of smart era, demand for clean energy is rising, and flexible triboelectric nanogenerators (F-TENGs) based on elastomers have garnered significant attention. Based principles electrostatic induction coupling, F-TENGs can convert mechanical motion into electrical are widely utilized in wearable devices blue energy. offer a simple design, ease manufacturing, usage scenarios. However, several weaknesses still limit their development. For example, F-TENG materials cannot recover from fatigue damage prone to output performance degradation under frequent friction or complex external conditions, leading failure. To address these issues, researchers explored use self-healable polymer-based layers electrodes. This review will provide detailed summary key scientific technological challenges faced by harsh environments, including ambient, high low temperatures, humidity, strong acids bases. Furthermore, research progress addressing issues future development also be presented explored. paper aims valuable insights guidance in-depth broad applications TENGs.

Abstract Human tactile perception involves the response of skin receptors to external stimuli and processing this information by central nervous system. However, pressure sensors based on a single sensing mechanism face challenges when applied as biomimetic skins for simultaneous mechanical stimulus object recognition. Here, it is propose that multifunctional ionic fiber membrane, modified with 1‐ethyl‐3‐methylimidazolium dicyandiamide ([EMIM][DCA]), can achieve high‐performance capacitive triboelectric generation. [EMIM][DCA] highly doped into thermoplastic polyurethanes through unique hydrogen bonds, resulting in sensor ultra‐high sensitivity (184.3 kPa −1 ) ultra‐low detection limit (1.9 Pa). Dicyandiamide ions introduce electron‐donating groups positive layer, increasing output performance nanogenerators (TENG) 2.47 times, excellent stability exceeding 20 000 cycles. By integrating these properties, an intelligent glove developed capture subtle gripping motions identify different materials. Expanding array TENG machine learning automated sorting gripper further enhance variety recognized objects improve material recognition accuracy 99.17%. This strategy offers more comprehensive approach imparting artificial robots, demonstrating significant potential human‐machine interaction.
