| 摘要: | 近年來，穿戴式電子裝置在健康監測領域的應用愈加廣泛，這些裝置能即時偵測使用者的健康狀況，並通過有線或無線方式將數據傳送至接收裝置，必要時再傳至雲端進行處理，以達成即時健康監控的目的。同時，智慧型傷口敷料的發展亦引起了越來越多的關注。傳統的智慧型傷口敷料主要依賴於軟性印刷電路板(FPC)，然而，這類技術雖適合大規模生產，但在面對個別患者需求的客製化生產時，成本將大幅增加。積層製造技術因其能夠列印複雜外型，特別適合用於針對不規則形狀傷口的智慧型敷料客製化生產。
本研究基於積層製造技術，使用高解析度光固化成形技術製作了一款雙層智慧穿戴式繃帶。該貼片結構包含生物電阻抗電極電路和 3x3 多光譜光療模組電路，其電路直接列印於撓性基板上，並將發光二極體嵌入基板中，從而減少裝置整體厚度並提高電路穩定性。導電電路透過直接墨水書寫技術列印導電墨水，並在固化後，將兩片撓性基板利用基板材料作為黏著劑進行接合，最終再以導電墨水連接導通接合後的雙層基板電路。此外，為了均勻擴散多光譜光療模組的光線和保護發光二極體，防止外部環境對電路和電子元件的影響，研究中使用了二氧化矽與聚二甲基矽氧烷混合的光擴散層進行封裝。
該穿戴式繃帶可透過微處理器結合低功耗藍牙技術，以無線方式由手機 APP 控制其生物阻抗測量和多光譜光療模組的操作，讓使用者能夠迅速獲取並管理健康資訊。為驗證貼片的可靠性，本研究將進行阻抗量測分析、不同彎曲條件下的電路穩定性測試、表面溫度穩定性測試及光擴散層性能評估。;In recent years, wearable electronic devices have found increasingly broad applications in health monitoring. These devices can detect the user’s health status in real time and transmit data to receiving devices via wired or wireless communication. When necessary, the data can be sent to the cloud for processing, enabling real-time health monitoring. Simultaneously, the development of smart wound dressings has garnered growing attention. Traditional smart wounddressings primarily rely on flexible printed circuit boards (FPC). While these technologies are suitable for mass production, they significantly increase costs when customized for individual patient needs. Additive manufacturing, with its ability to fabricate complex shapes, is particularly well-suited for producing custom smart dressings tailored to irregularly shaped wounds.
This study utilizes additive manufacturing to develop a dual-layer smart wearable bandage using high-resolution photopolymerization technology. The patch structure includes bioimpedance electrode circuits and multispectral phototherapy module circuits. The circuits are directly printed onto flexible substrates, with light-emitting diodes (LEDs) embedded in the substrate, reducing the overall thickness of the device and enhancing circuit stability. Conductive circuits are printed using direct ink writing (DIW) of conductive ink, and after curing, the two flexible substrates are bonded using the substrate material as an adhesive. The bonded double-layer substrate circuits are then electrically connected with conductive ink.Furthermore, to evenly diffuse light from the multispectral phototherapy module and protect the LEDs from external environmental impacts, a light-diffusion encapsulation layer, composed of a mixture of silicon dioxide and polydimethylsiloxane (PDMS), is employed.
The wearable bandage integrates a microcontroller and low-power Bluetooth technology, enabling wireless control of bioimpedance measurement and the operation of the multispectral phototherapy module via a smartphone app. This allows users to quickly access and manage health information. To validate the patch’s reliability, the study will conduct impedance measurement analysis, circuit stability tests under different bending conditions, surface temperature stability tests, and performance evaluations of the light-diffusion layer. |
