With the arrival of the Internet of Things era, the demand for tactile sensors continues to grow. However, traditional sensors mostly require an external power supply to meet real-time monitoring, which brings many drawbacks such as short service life, environmental pollution, and difficulty in replacement, which greatly limits their practical applications. Therefore, the development of a passive self-power supply of tactile sensors has become a research hotspot in academia and the industry. In this review, the development of self-powered tactile sensors in the past several years is introduced and discussed. First, the sensing principle of self-powered tactile sensors is introduced. After that, the main performance parameters of the tactile sensors are briefly discussed. Finally, the potential application prospects of the tactile sensors are discussed in detail.

The triboelectric nanogenerator (TENG) offers a novel approach to harness mechanical energy continuously and sustainably. It has emerged as a leading technology for converting mechanical energy into electricity. The demand for self‐powered wearable microelectronics and energy generation in extreme conditions underscores the need for efficient high‐temperature operatable TENGs (HTO‐TENGs). However, the operating environment temperature not only affects the storage and dissipation of electrons during triboelectrification, leading to decreased output performance of TENG and instability at high temperatures, but also damage to the mechanical stability and effective defects in most tribo‐materials, resulting in a further reduction in TENG's effective output power. Moreover, the unstable material properties of the triboelectric layer at high temperatures also restrict the use of the TENG in harsh environments. Therefore, it is imperative to consider the structural durability and electrical output stability of TENG when applying it in challenging working environments. This review aims to bridge this gap by providing a comprehensive overview of the current state and research advancements in HTO‐TENG for the first time. Finally, this review presents insights into future research prospects and proposes design strategies to facilitate the rapid development of the field.

In light of the escalating requisites for portability, functionality, comfort, and health in electronic apparatus, the imperative advancement of sophisticated multifunctional textile‐based triboelectric nanogenerators (textile‐TENGs) is underscored. This research delineates the fabrication of an innovative multifunctional textile‐TENG, comprising a photosensitive stratum aimed at thermal regulation and photothermal therapy, alongside a tribo‐negative nanofiber film adorning its verso. Exhibiting superlative electrical prowess, the textile‐TENG generates remarkably elevated outputs over a wide temperature range, thereby facilitating the efficacious conversion of kinetic energy derived from human motion into electrical energy. Concurrently, the device manifests an exceptional photothermal conversion efficiency, achieving instantly modifiable saturation temperatures (41.52–60.97 °C) under diverse solar exposures, rendering it eminently suitable for a broad spectrum of applications in thermal therapy and regulation domains. Significantly, within cold environments, the textile‐TENG demonstrates a capability to augment temperature by approximately 7.4 °C, markedly surpassing conventional cotton textiles in performance. In summation, the textile‐TENG is characterized by its unparalleled electromechanical attributes and photothermal conversion efficacies, concurrently facilitating thermal regulation, therapy, and electricity generation. This investigation not only furnishes a referential methodology for the development of advanced multifunctional textile devices but also substantially expands the conceivable application ambit of textile‐based technologies.
