The droplet electricity generator (DEG) is a solid-liquid triboelectric nanogenerator with transistor-inspired bulk effect, which regarded as an effective strategy for raindrop energy harvesting. However, further enhancement of DEG output voltage necessary to enable its widespread applications. Here, high-entropy ceramics are integrated into the design intermediate layer first time, achieving high 525 V. High-entropy have colossal dielectric constant, can help reduce charge decay DEG. Furthermore, effect factors on performance when employing extensively analyzed, and underlying mechanisms mathematical models explored. Finally, enhanced not only facilitates faster harvesting but also develops novel method rapid bacterial detection. This work successfully integrates design, significantly enhances voltage, offers direction development.

Energy harvesting from ambient sources present in the environment is essential to replace traditional energy sources. These strategies can diversify sources, reduce maintenance, lower costs, and provide near-perpetual operation of devices. In this work, a triboelectric nanogenerator (TENG) based on silane-coupled Linde type A/polydimethylsiloxane (LTA/PDMS) developed for harsh environmental conditions. The LTA/PDMS-based TENG produce high output power density 42.6 µW/cm
