“…As an important product of internet development, virtual reality (VR) and augmented reality (AR) aim to enable the input and output of analogue signals for multiple senses such as sight, smell and touch, providing a near-realistic virtual experience for humans. The high voltage, low current and wide range of material options of wearable TENG devices are facilitating the manufacture of VR and AR devices [ 122 , 123 ]. Pu et al reports a TENG-based micromotion sensor that can effectively capture blink motion at super-high signal level (~ 750 mV) and can be applied to wireless hands-free typing systems (Fig.…”

The triboelectric nanogenerator (TENG) can effectively collect energy based on contact electrification (CE) at diverse interfaces, including solid–solid, liquid–solid, liquid–liquid, gas–solid, and gas–liquid. This enables energy harvesting from sources such as water, wind, and sound. In this review, we provide an overview of the coexistence of electron and ion transfer in the CE process. We elucidate the diverse dominant mechanisms observed at different interfaces and emphasize the interconnectedness and complementary nature of interface studies. The review also offers a comprehensive summary of the factors influencing charge transfer and the advancements in interfacial modification techniques. Additionally, we highlight the wide range of applications stemming from the distinctive characteristics of charge transfer at various interfaces. Finally, this review elucidates the future opportunities and challenges that interface CE may encounter. We anticipate that this review can offer valuable insights for future research on interface CE and facilitate the continued development and industrialization of TENG.

Easy and convenient reading for blinds is of great significance for lowering their learning, entertainment, and communication barrier, and improving their living quality. The general solution is to learn braille, far from satisfying the meet of the blinds’ daily learning and communication. Here, a new‐type conductor/insulator‐identifiable e‐tattoo proximity sensor is developed by simply depositing the circular interdigitated electrodes on organic semiconductor. The discriminable recognition toward conductors and insulators is realized only based on a single e‐tattoo device. The sensors not only enable recognition of the protruding characters like braille based on distance difference, but also enable recognition of the handwriting ink‐brush and pencil graphite characters based on the unique advantage of the sensors in distinguishing conduct and insulator. These results open a new route to realize the material category recognition, provide a user‐friendly way to help the visual impaired effectively reintegrate into society, and broaden the application field of proximity sensors.
