The present invention relates to an intelligent wearable device for calculating body weight and a method thereof. The intelligent wearable device includes a carrier and a data recorder. The carrier is installed with at least one heel piezoelectric element, at least one foot piezoelectric element, a central control module, a power conversion module, and a power storage module. The heel piezoelectric element and the foot piezoelectric element are pressed by foot to generate pulse signals during walking of a wearer. The central control module includes a processor and a wireless transmission unit. The plurality of pulse signals are calculated by the processor according to an algorithm so as to obtain a plurality of feature vectors. The wireless transmission unit transmits the plurality of feature vectors to the data recorder. The data recorder compares the plurality of feature vectors with a remote database for calculating body weight. In addition, the power storage module is charged after the pulse signal is converted by the power conversion module, so as to achieve the purposes of self-power-generation and continuous measurement.一種計算體重之智能型穿戴式裝置及方法,包括一載具及一資料記錄器,該載具安裝著至少一腳跟壓電元件、至少一腳掌壓電元件、一中央控制模組、一電能轉換模組、以及一儲電模組,該腳跟壓電元件及該腳掌壓電元件在穿戴者行走過程受足部施力而產生脈衝信號,該中央控制模組包括一處理器及一無線傳輸單元,該複數個脈衝信號經該處理器依一演算法運算而得複數個特徵向量,再由該無線傳輸單元將該複數個特徵向量傳輸至該資料記錄器,由該資料記錄器與一遠端資料庫比對而計算出體重,另外該脈衝信號經由該電能轉換模組轉換後對該儲電模組充電,達到自我發電永續量測的目的。1‧‧‧載具11‧‧‧腳掌區12‧‧‧足弓區13‧‧‧腳跟區14‧‧‧第一防水護層15‧‧‧第二防水護層2‧‧‧資料記錄器3‧‧‧腳跟壓電元件4‧‧‧腳掌壓電元件5‧‧‧中央控制模組51‧‧‧處理器52‧‧‧無線傳輸單元6‧‧‧電能轉換模組7‧‧‧儲電模組
