A smart clothing includes a clothing, at least a detection module which is combined with the attachment layer and located between the clothing and the attachment layer, a wireless transceiver which is arranged on the outer surface of the back side of the clothing, a server which is connected with the wireless transceiver and includes an operation unit, a physiological database and a cloud communication unit, and a mobile device which is connected through the The cloud communication unit is connected to the server.Therefore, by setting the detection module on the inner side of the back of the smart clothes, which is relatively stable above the ribs, and the back is also a relatively less moving part, the smart clothes can make the detected data more stable and accurate, and enable users to detect and obtain stable and accurate physiological signals at any time in a comfortable and free movement situation. It will not make life inconvenient.一種智慧衣,係包括一衣物;至少一偵測模組,係與該貼附層相結合且位於該衣物與該貼附層之間;一無線收發器,係設置於該衣物背側外表面;一伺服器,係與該無線收發器連接並包括有一運算單元、一生理資料庫及一雲端通訊單元;以及一行動裝置,係透過該雲端通訊單元與該伺服器連接接。藉此,本創作所提智慧衣,透過將該偵測模組設在該衣物背側內面且位於肋骨上方係具有相對穩定性,且背部也是比較不會太常移動之部位,可使偵測所得數據更穩定且準確,並能達到讓使用者可在舒適且自由活動之情形下,隨時偵測並獲得穩定、準確之生理訊號,而不會造成生活上不方便。
