A signal process system and the method for the same and a bioimpedance detection device and element used to perform corresponding signal process for sensory signal sensed by a sensor, wherein a minor AC electrical signal is injected into a biological tissue to be measured in order to sense the sensory signal of the biological tissue to be measured by means of the principle of Ohm’s Law. Moreover, the sensory signal may be processed to output a first digital output signal related to gain, and both of the minor AC electrical signal and the sensory signal may be processed to output a second digital output signal related to phase for a biological property of the measured biological tissue to be restored from the first digital output signal and the second digital output signal and an equivalent circuit parameter model representative of the biological property may be created. 【代表圖】本發明提出一種信號處理系統及方法與生物阻抗檢測裝置及元件，用以對感測器所測得的感測信號進行對應之信號處理，係注入一微小交流電信號來通過該待測量之生物組織，並藉由歐姆定律的原理使該感測器得以感測出該待測量之生物組織的感測信號；以及對該感測信號進行處理以輸出與信號強度相關的第一數位輸出信號，並對該微小交流電信號與該感測信號兩者進行處理以輸出與相位相關的第二數位輸出信號；藉此，利用該第一數位輸出信號以及第二數位輸出信號還原該待測量之生物組織的生理特性以及建立用以表示該生理特性的等效電路參數模型。
