Abstract:	以層狀金屬硫化物 (Layered Metal Dichalcogenides, LMDCs) 為基底之壓電領域應用已受到廣泛矚目，特別在於微型化能源裝置以及穿戴式感測系統。然而，輸出不足的問題仍是其一大挑戰。本研究中，我們嘗試以化學氣相沉積法製備異質結構，並探討此結構之本質壓電特性以及其壓電提升機制。我們也進一步將其導入於壓電奈米發電機 (piezoelectric nanogenerator, PENG) 元件與自供電應變感測器設計。最重要的是，我們也成功將此異質結構之奈米發電機元件，應用於多元人體動作監測，展示其作為下一世代高靈敏穿戴式生醫感測系統之潛力。 ;Layered Metal Dichalcogenides (LMDCs) has attracted widespread attention in the field of piezoelectric system, especially for miniaturized energy devices and wearable sensing systems. However, the issue of insufficient output still remains a critical challenge. In this study, we developed a heterostructures of by using (Chemical Vapor Deposition, CVD), and investigated their intrinsic piezoelectricity and related mechanism to the enhancement. Moreover, we further integrated them into a piezoelectric nanogenerator (PENG) device and self-powered strain sensors. Most importantly, we successfully applied the PENG to monitor various human movements, demonstrating its potential as the next generation highly sensitive wearable biomedical sensing systems.
