醫療穿戴式裝置可以擷取、生成及分享穿戴者的生理數據,使醫護人員可以透過數位連線方式,為患者進行遠距診斷與治療。醫療穿戴式裝置中最重要的部分是軟性印刷電路板,具有重量輕、厚度薄及體積小等優點。目前主流的製造技術較適合用於單一規格的大量製造應用中,但醫療穿戴式裝置需要根據患者的不同需求進行客製化,若使用主流的製造技術進行客製化生產,會使成本增加許多。積層製造技術是一種層層堆疊成型的製造技術,可以製作出複雜的三維結構,也可以在模型內部設計結構。由於此技術具有高度的設計自由度,可以滿足醫療穿戴式裝置的客製化需求。
本研究以積層製造技術為基礎,開發具可撓性、親膚性及可客製化的軟性印刷電路板製程,為醫療穿戴式裝置的客製化應用需求提供一種解決方法。本研究選擇使用積層製造技術中具有極高解析度的光固化成型技術製作軟性基板,並將設計的電路圖案也列印於基板上。接著以直接墨水書寫技術列印導電墨水,將導電墨水固化後形成導電電路。根據表面貼裝技術開發一套電子元件貼裝方法,最後再以直接墨水書寫技術列印軟性封裝材料於成品表面,封裝材料固化後形成封裝層,避免電路與電子元件受到外部環境的影響,延長成品的使用壽命並提高其可靠性。
完成上述製程後,本研究以傷口護理的醫療穿戴式裝置為範例,設計兩款傷口護理的應用模組,分別為具有加速傷口癒合效果的多光譜光療模組,以及具有傷口癒合監測效果的生物阻抗量測模組。以開發的製程製作模組成品後,進行通電後的功能測試、機械性質測試、在不同彎曲狀態下的電路穩定性及運作時的表面溫度穩定性等實驗,驗證模組的可行性。
Medical wearable devices can retrieve, generate and share the wearer’s physiological data, enabling medical personnel to provide remote diagnosis and treatment to patients through digital connections. The most important part of medical wearable devices is the flexible printed circuit boards, which has the advantages of being lightweight, thin and small. Current mainstream manufacturing technologies are more suitable for mass manufacturing of single specification applications. However, medical wearable devices need to be customized according to the different needs of patients. Using mainstream manufacturing technologies for customized production would significantly increase costs. Additive manufacturing technology, which builds layer by layer, can create complex three-dimensional structures and design internal structures within models. Due to its high degree of design freedom, this technology can meet the customization needs of medical wearable devices.
This research is based on additive manufacturing technology to develop a flexible, skin-friendly and customizable flexible printed circuit boards process, providing a solution for the customized application needs of medical wearable devices. The study utilizes high-resolution photopolymerization technology in additive manufacturing technology to produce flexible substrates and prints the designed circuit patterns onto the substrates. Next, conductive ink is printed using direct ink writing technology, which is then cured to form conductive circuits. A method for mounting electronic components is developed based on surface mount technology. Finally, flexible encapsulation material is printed onto the surface of the product using direct ink writing technology. After the encapsulation material is cured, it forms an encapsulation layer that protects the circuit and electronic components from external environmental influences, thereby extending the product's lifespan and enhancing its reliability.
After completing the aforementioned process, this research uses the medical wearable device for wound care as an example to design two application modules for wound care: a multispectral phototherapy module that accelerates wound healing and a bioimpedance measurement module that monitors wound healing. The modules are fabricated using the developed process, followed by functional testing under power, mechanical property testing, circuit stability testing under different bending conditions, and surface temperature stability testing during operation to verify the feasibility of the modules.
