This work proposes a structure of physiological signal acquisition element.At least, the utility model comprises a physiological signal sensor or an adapter of the physiological signal sensor and an electrical protection component containing a conductive material.Among them,The electrical protective parts containing conductive materials are electrically insulated from the physiological signal sensor or the adapter of the physiological signal sensor.Between the adapter of the physiological signal sensor or the physiological signal sensor and the electrical interference source,And then it is electrically connected with the electric ground or power supply or shielded driving circuit or human body or any combination of the above.In order to prevent the physiological signal sensor from moving in the human body,Disturbance due to clothing disturbance,Measurement error occurs.本創作係提出一種生理信號擷取元件之構造，至少包含有生理信號感測器或生理信號感測器之適配器和含導電性材料的電氣防護部件，其中，含導電性材料的電氣防護部件與生理信號感測器或生理信號感測器之適配器係電氣絕緣，且置於生理信號感測器或生理信號感測器之適配器與電氣干擾源之間，再與電氣地或電源或屏蔽驅動電路或人體或上述各項之任意組合電氣連接，以防止生理信號感測器於人體活動時，因衣物擾動而產生干擾，發生量測失準。
