高齡化對社會的影響除了整體生產勞動力下降之外，老年人疾病問題往往導致家庭經濟與生活的嚴重影響。老年人由於生理功能的下降，身體疾病的表徵往往不明顯，如果又罹患失智症或中風，導致言語表達困難無法溝通，疾病就更難早期偵測。許多急性疾病都有治療的黃金時間，過去依賴家人或照護者被動發現病徵的老人照護模式，如果能改為穿戴式設備進行日常生活的健康監控，或早期偵測老年患者重大疾病的徵兆，結合行動科技通訊上傳資料，就有機會大幅改善老年人之健康。目前已經商業化且價格平易近人的穿戴式裝置小米手環第二代其行動生理偵測系統包括心率、計步器、睡眠品質監控，連續監測的性質產生了龐大的數據，數據是否能更正確且即時的反應是能否應用於老年預防醫學的關鍵，目前全世界都在摸索，如何建立一個整合的模式成功將連續性行動生理監測用於老人預防醫學。因此本研究的目標為確認小米手環等市售行動生理監控裝置應用於老年人，其準確性是否符合醫療級儀器所檢測結果未來是否可輔以臨床效益的實證評估，為預防醫學做準備。

Aging is a natural and inevitable process. As the medical costs associated with aging have risen steadily over the past decades, many researchers have sought alternative ways to treat conditions caused or induced by aging. While exercise has been shown to effectively delay aging and prevent aging-related medical problems, individuals vary in many ways, and incorrect exercise could actually cause damages to human body. Therefore, it is better if individuals conduct exercise with professional trainers to prevent physical damages, but doing so would drastically increase the staffs required and thus the medical costs. Fortunately, the technological advancement fast, and the developments of wearable physiological and monitoring devices, ordinary people can detect their physiological changes without going through invasive monitoring. In this project, we propose to collect the heart rate information in the elderly, through continuing monitoring of individual physiological and biological indicators. We seek to observe significant correct information shown on MI band. Our goal to establish the most wearable driver such MI bans to reduce the risk associated with improper exercises and to achieve individualized medical treatment, exercise instruction and health promotion.
