Summary: In the era of IoTs, triboelectric nano-generators (TENGs) are widely researched for self-powered sensing due to their high efficiency, versatile configuration, and low cost. However, the inherent variation of TENG outputs limits their direct use as primary sensing signals. To solve this issue, a new method is proposed to extract the sensing signal that is independent of TENG output variations. This method accurately determines applied strain using the ratio of currents in two parallel branches, eliminating the effect of output variations and providing a self-powered sensing solution.

Summary: Liquid-solid triboelectric nanogenerators (L-S TENGs) generate electrical signals through the contact separation of droplets and dielectrics, which have wide applications in energy harvesting and self-powered sensing. However, the contact between droplets and electret can degrade L-S TENG's performance. In this study, a noncontact triboelectric nanogenerator (NCLS-TENG) is proposed, which can sense droplet stimuli without contact and convert them into electrical energy or signals. NCLS-TENG shows great potential in smart medical and wearable applications.

Summary: This study proposes an ultra-robust and high-performance rotational triboelectric nanogenerator (R-TENG) by using a bearing charge pumping mechanism. The R-TENG consists of a pumping TENG (P-TENG), an output TENG (O-TENG), a voltage-multiplying circuit (VMC), and a buffer capacitor. The P-TENG is designed with a freestanding mode based on a rolling ball bearing, which serves as the rotating mechanical energy harvester. The low charge generated by the P-TENG is accumulated and pumped to the non-contact O-TENG, resulting in reduced mechanical wear and increased output performance. The matched instantaneous power of R-TENG is increased by 32 times at 300 r/min, and the transferring charge remains at 95% during 15 days of continuous operation (6.4 x 10(6) cycles). This work presents a feasible method to enhance the durability of TENG, which can facilitate the practical applications of high-performance TENG in harvesting distributed ambient micro mechanical energy.

Summary: Triboelectrification between metals, polymers, and semiconductors was investigated, revealing a universal mechanism involving both electrostatic induction and dynamic junction modulation. The outputs of triboelectrification exhibited four current/voltage peaks, two of which were attributed to electrostatic induction effects and determined by surface state densities and electron affinity differences between the materials. The other two peaks were associated with dynamic junction modulation effects and determined by charging exchange between surface states and depletion regions. While metals and polymers showed no modulation of depletion regions, only the peaks induced by electrostatic induction were observable. Semiconductors, on the other hand, exhibited additional peaks induced by junction modulation when in contact with any material type. These findings provide valuable insights for developing high-performance triboelectric nanogenerators.
