High-Performance (Zn_0.5Mg_0.5)TiO₃ Ceramics Based Composite Films for Powering a Multimode Translation Unit and Human Motion Monitoring

The high operating temperature of the multimode translation unit presents persistent challenges in ensuring rapid power supply during emergency situations. To tackle this challenge, (Zn0.5Mg0.5)TiO3 (ZMT) ceramic powder, known for its exceptional dielectric properties and high dielectric constant, was selected. It was combined with P(VDF-TrFE) to develop composite films exhibiting stable performance across varying temperatures. Leveraging the triboelectric mechanism, ZMT/P(VDF-TrFE) composite films were employed as the triboelectric layer to develop high-performance and temperature-stable self-powered devices. A remarkable open-circuit voltage of 451.63 V and a short-circuit current of 9.41 μA were observed in the ZMT-based triboelectric nanogenerator (ZMT-TENG), highlighting its potential for high-performance applications. It achieved a 21.1 times increase compared to traditional ceramic-based P(VDF-TrFE) TENGs, representing the highest electronic performance documented in the literature to date. Remarkably, VOC and ISC variations remained within 20% over a wide temperature range from −10 to 180 °C. This study not only advances TENG performance through material innovation but also enhances temperature stability, improving its effectiveness for both multimode translation units and high-precision human motion monitoring.
