Summary: In this paper, TiO2/Ni/C composites were prepared using MOF-derived Ni/C materials for SO2F2 detection at room temperature. The TiO2/Ni/C composites-based SO2F2 sensor shows a wide detection range and fast response/recovery time, with a higher response value compared to the pure TiO2-based sensor. A dual-layer hybrid TENG based on TiO2/PVDF composite film was constructed, which enables a self-powered temperature and humidity-corrected SO2F2 sensing system. This work broadens the application of TENG in self-powered gas sensing and provides a new idea for trace detection of SO2F2 at room temperature.

Summary: This study presents a novel approach for traffic monitoring using a waterbomb-origami-inspired triboelectric nanogenerator (WO-TENG). The WO-TENG integrates smart pavement and offers lightweight, cost-effective, excellent deformability, flexibility, and self-rebounding properties.

The fully-packaged self-driven WO-TENG successfully decouples the influence of vehicle speed and weight on sensing accuracy, indicating its feasibility and stability for traffic monitoring. Accurate evaluation of vehicle speed, number, and types can be achieved, regardless of voltage amplitude and time interval electrical wave.

Summary: A general theoretical analysis of a 3D generic TENG structure is presented in this paper. It is found that the optimal TENG geometry is independent of the frequency of the moving dielectric, but the external ohmic impedance for maximum power output is inversely proportional to the frequency. The energy of the TENG is proportional to the cube of its size, the square of the triboelectric charge density, and the angular frequency of the moving dielectric.
