矽橡膠為現今常用之工程塑膠之一。矽橡膠優異的化學安定性、機械性質與生物相容性使其發展出各式各樣的商業用途，例如：封裝、管材、模具等等。奈米碳管自1991年被發現以來，由於其特殊的電導、熱導與機械性質使科學家爭相研究。本實驗針對上述材料，以三軸滾輪作為機械剪切力均勻混合得到奈米碳管－矽橡膠複合材，使絕緣的矽橡膠可以導電，並討論其機械強度、電性、電熱效應與壓阻性質。由於矽橡膠柔軟、親膚的特性，我們將此複合材製作成恆溫加熱裝置與穿戴式手部動作感應器。此實驗之恆溫加熱裝置以低功率方式儲存熱能並擁有高效率恆溫的優勢可應用於中醫熱墊及醫療用長照保暖設備。而穿戴式手部動作感應器則對於形變有極高的靈敏度也可應用於年長者居家感測器，例如裝置於拖鞋、運動鞋、木地板、座椅、床墊得以感測老人行動安全(跌倒、碰撞)或裝設於木地板、門窗取代傳統紅外線感應並提高保全防竊偵測能力。本實驗製程適合大量製造，具商業潛力及未來商品化價值。

Silicone rubber is one of the most common engineering plastics. Lots of related applications have been developed owing to its extraordinary chemical stability, mechanical property and biocompatibility, such as packaging and molding. On the other hand, since carbon nanotubes (CNTs) were discovered in 1991 scientists has made efforts to study tube properties and applications because of their fascinating electronic, thermal conductivity and mechanical strength. Study here focuses on silicone rubber-CNTs composites homogeneously mixed by shear stress driven three-roller device. Composites show joule heating effect and electro-resistive effect. We then design heating elements and finger motion detector based on composite; the former shows an efficient storage of heat energy at a low power input. The latter however behaves as good sensors upon straining. The fabrication here takes advantage for mass production, hence the potential in future applications.
