The present invention relates to a multi-purpose physiological detecting device, which is implemented in an ear wearing form, and, through a special electrode configuration design, capable of contacting different parts of the body to respectively obtain ECG signals of different projection angles even if the same device is used. The multi-purpose physiological detecting device comprises: a physiological signal capturing circuit； a first ear wearing structure and a second ear wearing structure for being respectively disposed on two ears of a user； and a first signal capturing electrode and a second signal capturing electrode respectively disposed on the first ear wearing structure and the second ear wearing structure, and electrically connected to the physiological signal capturing circuit. The first signal capturing electrode is configured to contact one of the following parts: an upper limb and a torso, and the second signal capturing electrode is configured to contact one of the two ears and/or the head region in the vicinity thereof, wherein the physiological signal capturing circuit can obtain an ECG signal by using the first signal capturing electrode and the second signal capturing electrode to respectively contact the skin.本發明相關於一種多用途生理檢測裝置，實施為耳戴形式，可透過特殊的電極配置設計，即使使用同一個裝置，亦可與身體不同部位接觸而分別取得不同投影角度的心電訊號。
