摘要

在本論文中利用摩擦起電效應來產生摩擦電荷，並藉由集能元件之特殊結構設計，將產生之摩擦電荷收集利用。本論文之摩擦集能元件結構為絕緣基板上蒸鍍一銀金屬電極用以將電荷導出至外部線路，而在金屬電極之上須在塗佈一層對聚二甲基矽氧烷，並將此結構裝置在一盒子內，最後再放入些許鋁金屬顆粒直至均勻覆蓋盒子底層，即可藉由鋁金屬顆粒與對聚二甲基矽氧烷摩擦產生可收集之能源。在此元件基礎上，想改進元件功率並提升電流，因此作了下列變因探討: 元件裝置外盒材質(接地與否)、不同摩擦材料粒徑大小(5mm/1mm)對於電性之影響、在摩擦電層與電極間插入絕緣層對於電性之影響、在對聚二甲基矽氧烷中摻入奈米碳管後之電性變化、以及將此架構對比常見之壓力式感應元件。從結果分析，可得知搖晃式元件結構能夠提供比壓力式元件更大功率、此元件須將外盒接地導出累積電荷才得以運作(因此選定外盒為金屬盒子)、摩擦材料(鋁金屬)粒徑5mm所產生之功率較大、在摩擦電層與電極間插入絕緣層後元件有些許提升、在對聚二甲基矽氧烷中摻入奈米碳管後對於元件功率有些許提升。

In this paper, the triboelectric effect is used to generate triboelectric charges, and the triboelectric charges generated are collected and used by the special structure design of the energy-collecting element. The structure of the shaking triboelectric energy harvester in this paper is that a silver metal electrode deposited on an insulating substrate to collect the triboelectric charges to the external circuit, and then cover the electrode by a layer of PDMS. After all the process above, make the electrode stick on the top and bottom of a box, then put some aluminum metal particles until the bottom layer of the box is uniformly covered. Finnally friction of the aluminum metal particles with PDMS generates collectable energy. Based on this component, we want to improve the power and current of the component, so the following variables are discussed: Component device box material (ground or not), the impact of different friction material particle size (5mm / 1mm) on electrical properties, the impact of inserting an insulating layer between the triboelectric layer and the electrode on electrical properties, the electrical changes after the CNT is incorporated into the PDMS, and the pressure triboelectric energy harvester compared with this structure. From the analysis of the results, it can be seen that shaking triboelectric energy harvester can provide greater power than the pressure type triboelectric energy harvester. This component must operate in a grounding outer box in order to the ground to accumulate charges (so the outer box is selected as a metal box), and the friction material (aluminum metal) particles the power produced by a diameter of 5mm is larger, and the element is slightly improved after the insulating layer is inserted between the triboelectric layer and the electrode, and the power of the element is slightly increased after the CNT is added to the PDMS.
