The invention provides a portable physiological index device for providing a physical and mental reference index of a user, which includes a detection unit with a plurality of electrodes.Equal electrodes are provided on the user's skin to form a lead.The detection unit continuously detects the first muscle electrical signal and the output muscle electrical signal of one of the users' hearts for a predetermined time.The scheduled time shall be at least 20 seconds.Processing unit connection detection unit.The processing unit receives the myoelectric signal and performs a psychosomatic index algorithm to calculate the myoelectric signal to generate the corresponding psychosomatic reference index.Among them, the physical and mental reference index is a mood index, a stress index, a fatigue index, a digestion index and a sleep state index.Physical and mental index algorithm calculates the changes of myoelectric signal in frequency domain to convert it into corresponding physical and mental reference index.本創作係提供一種可攜式生理指標裝置，供提供一使用者的一身心參考指標，其包含一偵測單元具有複數電極。等電極供設置在使用者之皮膚以形成一導程。偵測單元以一預定時間持續地偵測使用者之一心臟的一肌電訊號及輸出肌電訊號。其中，預定時間至少要不小於20秒。處理單元連接偵測單元。處理單元接收肌電訊號與執行一身心指標演算法計算肌電訊號以產生對應的身心參考指標。其中，身心參考指標為一心情指標、一壓力指標、一疲勞指標、一消化指標與一睡眠狀態指標。身心指標演算法係演算肌電訊號於頻域上的變化，以轉換成對應的身心參考指標。
