Abstract
根據世界衛生組織資料,全球糖尿病患者已突破五億人,血糖代謝異常問題亦在健康與亞健康族群中逐漸普遍。然目前臨床所用血糖監測方式多為侵入式,包含指尖採血與微針感測,雖具高準確性,卻因不適感與感染風險,降低使用者依從性。因此,開發具舒適性與高接受度之非侵入式血糖感測技術,成為近年重要的研究方向。
因此本研究開發一套結合漫反射光譜技術(Diffuse Reflectance Spectroscopy, DRS)與機器學習演算法的非侵入式血糖預測系統。系統透過多波長光源照射皮膚組織並量測反射光訊號,搭配空腹血糖值作為個體背景變數,以提升預測模型對代謝差異的辨識能力。資料經前處理與 Z-score 標準化後,模型建構採用隨機森林回歸演算法(Random Forest Regressor),具備處理非線性與高變異特徵的能力,預測結果整體落於臨床可接受範圍,展現良好穩定性與實用性。
為降低組織液中電解質(如KCl、NaHCO₃、CaCl₂)對光訊號的干擾,本研究亦於前期第一代感測裝置中導入動態補償機制,並以小批量資料進行驗證。惟後續裝置波長設定已更新,補償參數無法直接延用,故相關機制僅保留作為前期方法論依據。
綜上所述,本研究成功驗證非侵入式血糖感測結合光學技術與演算法可行性,具備模組化應用潛力,未來可整合至穿戴式裝置中,實現即時、無痛與個人化之血糖監測系統。
