“…Solid–liquid friction-based TENGs have attracted much attention in recent years. A polytetrafluoroethylene (PTFE)-copper (PC-TENG) tube with a single-electrode mode was fabricated by Munirathinam et al in 2022 [ 94 ]. As shown in Figure 6 e, the PC-TENG is used as a self-powered sensor to monitor intravenous (IV) fluid therapy unattended to detect blood pressure or heartbeat in biomedical settings.…”

With the development of 5G, artificial intelligence, and the Internet of Things, diversified sensors (such as the signal acquisition module) have become more and more important in people’s daily life. According to the extensive use of various distributed wireless sensors, powering them has become a big problem. Among all the powering methods, the self-powered sensor system based on triboelectric nanogenerators (TENGs) has shown its superiority. This review focuses on four major application areas of wireless sensors based on TENG, including environmental monitoring, human monitoring, industrial production, and daily life. The perspectives and outlook of the future development of self-powered wireless sensors are discussed.

Harnessing ambient renewable mechanical energies for achieving carbon‐neutrality demands the rational design of materials and architectures which are favorable for both energy collection and conversion simultaneously. However, the direct coupling of energy collection and conversion modules leads to many unwanted problems such as material wearing, the spatial constraint for large‐scale integration, and low energy conversion efficiency. Herein, a remote‐controlled energy harvesting strategy that cleverly harnesses the unique advantage of diffusive, long‐range airflow within a confined capillary channel is developed. The reported device separates the energy collection unit, made of an elastic cavity that directly transforms external mechanical motion to pneumatic motion, from the conversion units, made of encapsulated droplet chains that serve to translate their recurring motion within the capillary channel into electrical output. In contrast to single‐drain electrode design for electricity generation from fresh droplets in open spaces, two drain electrodes are designed to collect and release electrostatically induced charges from recurring droplets in the confined channel, respectively, thereby eliminating unwanted charge accumulation on recurring droplets and leading to efficient output performance. The integration of multiple electricity generation units with such a two‐drain electrode architecture with a single energy collector improves the design resilience and relaxes the spatial limitation.

“…In that context, triboelectric nanogenerators (TENG) stand out as a promising option among the various conceivable alternatives. [6][7][8] TENGs transform mechanical energy into electrical energy by utilising the triboelectric effect. 9,10 Contact electrication and electrostatic induction play an important role in the operation of the TENG, 11,12 therefore any modications and improvements to the TENG would revolve around these two phenomena.…”
