具有優異壓電性的功能型水凝膠在下一代自供電電子設備有極大的關注度。 然而，壓電水凝膠本身壓電性質的不確定性與傳統壓電水凝膠的電子設備輸出 性能不足限制了他們的發展性。本研究提出一種基於金屬二硫化物的奈米複合 壓電水凝膠，並探討所設計的壓電水凝膠整體的壓電特性。此外，我們將設計 好的壓電水凝膠整合到壓電奈米壓電元件中，此元件具備著 2.2 V、12 nA 的輸出表現，並具有 355 nW/m2 的瞬時功率密度，且可以對 1 μF 的電容器進行充放電。並且我們將其應用於不同重量、不同粗糙度的主動感測應用。 ;Functional hydrogels with excellent piezoelectric properties have garnered significant attention for next-generation self-powered electronic devices. However, the inherent uncertainty of the piezoelectric properties of piezoelectric hydrogels and the insufficient output performance of traditional piezoelectric hydrogels in electronic devices have limited their development potential. In this study, a piezoelectric gel (Piezogel) based on metal disulfide nanocomposites is proposed, and its overall piezoelectric characteristics are investigated. In addition, we will integrate the designed piezoelectric hydrogel into a piezoelectric nanogenerator, which exhibits an output performance of 2.2 V and 12 nA, with an instantaneous power density of 355 nW/m2, and can charge and discharge a 1 μF capactior. We will apply this device toactive sensing applications with different weights and suface roughness.
