隨著工業4.0與半導體科技發展使得科技進步迅速，且全世界人口持續增長，能源需求日益漸增且傳統能源有限，因此興起對綠色能源的發展，其中機械能獵能器具有可將環境中浪費的機械能收集轉換為電能特性，而摩擦發電機為機械能獵能器的一種，且能實現將機械能轉換為電能的效果，並應用於各種自供電設備。本文使用CO2雷射加工並結合高分子材料PDMS翻模技術及摻雜導電的碳材料，製作出微針狀結構及具有雷射紋理粗糙表面形貌。實驗發現微針狀結構及摻雜導電的碳材料摩擦層皆能夠提升摩擦發電輸出性能，因此本文將針對兩種摩擦層影響輸出電性能進行探討，並設計雷射加工參數，結合摩擦發電機以增強電性能輸出與應用搭配。
本文提出的微針狀結構摩擦發電機及摻雜導電的碳材料摩擦發電機分別具有開路電壓158.4/126.1 V、短路電流91.2/81.7 μA和最大瞬時功率8.28/5.24 mW，且分別為單次加工微針狀結構摩擦發電機與無摻雜摩擦發電機開路電壓的2.59/2.51倍、短路電流的2.57/2.19倍。將其應用於持久度、電容充放電與發光二極體驅動實驗，證明此結構穩定度，並分別於16/25秒內將0.47-10 μF的電容充電電壓至3.18 /2.08 V以上，亦分別驅動504/398個綠色LED，證明其可應用於自供電裝置與電子廣告看板等。接著將其對濕度的影響進行實驗，於相對濕度40%時會有最佳的輸出性能，當相對濕度值達到80%時，輸出性能分別僅剩下40%的0.12/0.14倍，由於相對濕度提升使表面產生水薄膜導致輸出性能下降。
將具有最高結構的雷射加工微針狀摩擦層進行壓力靈敏度感測，於0.5 - 4 kPa間靈敏度為14.1 V/kPa。並將其應用於自製垂直接觸分離式摩擦發電機發展為壓力感測器，結合Arduino UNO控制板作為人體運動感測系統，應用於手部復健輔助，未來能配合醫學相關需求與發展趨勢，實際應用於人體智慧監測與輔助器。

In this paper, we utilize CO2 laser processing, polymer casting technology, and the incorporation of conductive carbon materials (graphite) to fabricate microneedle structures and rough surface textures structure triboelectric layer of TENG.
This article proposed the microneedle structure TENG and the graphite-doped TENG which have open-circuit voltages of 158.4/126.1 V, short-circuit currents of 91.2/81.7 μA, and maximum instantaneous powers of 8.28/5.24 mW, respectively. which has 2.59/2.51 times and 2.57/2.19 times higher than those of a single-pass microneedle structure TENG and a pure TENG (without graphite doping), respectively.
The microneedle structure PDMS-TENG and graphite-doped PDMS-TENG can charge capacitors ranging from 0.47 to 10 μF to voltages above 3.18/2.08 V in 16/25 seconds, respectively, and they can drive 504/398 green-colored LEDs, showcasing their potential for applications in self-powered devices and electronic advertising billboards.
Moreover, we conduct humidity experiments and found that these TENGs exhibit the highest output performance at a relative humidity of 40%. However, when the relative humidity reaches 80%, the output performance of microneedle structure PDMS-TENG and graphite-doped PDMS-TENG will decrease about 0.12 times and 0.14 times if compared to the relative humidity of 40%.
Furthermore, the pressure sensitivity measurements of the microneedle structure of microneedle structure triboelectric layer were analyzed in this study. The highest height of microneedle structure has the highest mechanical sensitivity of 14.1 V/kPa in the low-pressure region (0.5-4 kPa). Then we apply the multi-pass microneedle structure triboelectric layer of TENG to develop a pressure sensor. The system is integrated with an Arduino UNO control board to create a human motion monitoring system for hand rehabilitation assistance. This application could be developed in the medical care industry and used for practical applications in human-machine interface (HMI).
