“…In general, the output performance can be effectively improved by increasing the surface charge density of the friction layer in TENGs. [177][178][179] Solid surface chemical functionalization is a practical and straightforward way to improve the surface potential. The introduction of groups with strong electron affinity on the surface of polymers is a common method for increasing their charge density.…”

“…Over the past few decades, the continuous development of the Internet of Things has prompted intensive research in clean and renewable energy converting strategies. Among the various energy harvesting technologies, the triboelectric nanogenerator (TENG) was invented to harvest the high-entropy mechanical energy in the environment such as wind, fluid, sound, and tide, thus representing a promising strategy for powering portable electronics in a distributed mode. − However, even with the vast amount of advantages such as low cost, simple structure, and wide materials selection, the poor output power of TENG that originates from its large internal impedance seriously limits its practical applications …”

The introduction of two-dimensional materials with high capacitance that are dielectric into the triboelectric interface is critical for the development of a highly efficient triboelectric nanogenerator (TENG) due to its excellent electrical conductivity and versatile surface chemistry. This paper reports a spring-structured multilayer TENG (S-TENG), where a Nb 2 CT x MXene-PVDF composite was chosen as the triboelectric electrode for increasing the dielectric and surface charge density. The intense electrostatic interaction of the strong hydrogen bonds between anions on the MXene surface and hydrogen atoms of PVDF chains not only creates a dipole in responding to the applied electric field but also promotes the formation of a piezoelectric phase and induces a strong interface coupling effect. Consequently, an output power enhancement of 300% was shown in comparison with pure PVDF, and a spring-like design with a multilayer structure further increases the space utilization and contact area and presents an output voltage of 420 V, a current density of 1.47 mA/m 2 , and a maximal output power density of 619 mW/m 2 . In addition, the as-prepared S-TENG can serve as both a fluid energy harvester on an urban river and a real-time monitor to realize the automatic alarm of water level warning.

Triboelectric nanogenerators (TENGs) are emerging as new technologies to harvest electrical power from mechanical energy. With the distinctive working mechanism of triboelectric nanogenerators, they attract particular interest in healthcare monitoring, wearable electronics, and deformable energy harvesting, which raises the requirement for highly conformable devices with substantial energy outputs. Here, a simple, low‐cost strategy for fabricating stretchable triboelectric nanogenerators with ultra‐high electrical output is developed. The TENG is prepared using PTFE micron particles (PP‐TENG), contributing a different electrostatic induction process compared to TENG based on dielectric films, which was associated with the dynamics of particle motions in PP‐TENG. The generator achieved an impressive voltage output of 1000 V with a current of 25 μA over a contact area of 40 × 20 mm2. Additionally, the TENG exhibits excellent durability with a stretching strain of 500%, and the electrical output performance does not show any significant degradation even after 3000 cycles at a strain of 400%. The unique design of the device provides high conformability and can be used as a self‐powered sensor for human motion detection.
