Here, we present the first gadolinium-based Curie triboelectric nanogenerator (GC-TENG) capable of harvesting thermal gradient energy at the gas-liquid interface. This device integrates a Curie engine with a solid-liquid-based triboelectric nanogenerator, enabling efficient two-step energy conversion from thermal gradient to mechanical to electrical energy. The optimized device incorporates ultra-lubricated ceramic bearings and high-performance magnets, achieving over 90 % transmission efficiency. It generates an open-circuit voltage of up to 220 V. Its charge density of 15 mC m⁻³ surpasses previous triboelectric nanogenerator-based thermal gradient energy harvesting technologies. The device's performance is enhanced through several innovations, including a high-efficiency power generator with exceptional bulk charge density characteristics and an optimized Curie engine with custom magnetic field design that boosts thermal conversion efficiency. The GC-TENG demonstrates excellent adaptability and stability, operating autonomously in real-world scenarios such as industrial wastewater discharge points.

The hybrid triboelectric nanogenerator (TENG) design addresses the fundamental trade-off between energy harvesting efficiency and pressure sensing performance found in single-mechanism sensors. By leveraging the high voltage output of the triboelectric effect at low pressures and the linear response of the piezoelectric effect to applied pressure, this sensor achieves a broad sensing range of up to 150 kPa, high sensitivity of 3.18 V/kPa, and an ultra-fast response time of 0.38 ms. The incorporation of MXene nanofillers enhances charge transport by forming conductive pathways within the polymer matrix, while the PVDF/MoS₂/MXene (PMMX) layer further improves frictional and piezoelectric responses. MXene’s high electronegativity and MoS₂’s piezoelectric properties contribute to increased sensitivity and charge transfer efficiency. When tested on various body parts, the sensor effectively detects human motion and supports energy harvesting. Furthermore, integration with a one-dimensional convolutional neural network (1D-CNN) achieves 99.18 % accuracy in gesture classification, demonstrating its potential for smart wearable applications.
