A sensing assembly includes a sensing device and a binding component. The sensing device includes a battery module, a circuit board module, and a physical condition sensor. The circuit board module covers a top surface, a bottom surface and a side surface of the battery module. The physical condition sensor is disposed on an outer surface of the circuit board module and configured to contact a sensing region of a user to detect a physical condition signal of the sensing region. The binding component is coupled to the sensing device to fix the sensing device to the sensing region of the user.一種感測裝置總成包括一感測裝置以及一固定元件。感測裝置包括一電池模組、一線路板模組、一生理狀態感測器，其中線路板模組覆蓋電池模組的一上表面、相對上表面的一下表面以及連接上表面及下表面的一側表面，生理狀態感測器設置於線路板模組的一外表面並適於接觸一使用者的一待感測區域，以感測待感測區域的一生理參數訊號。固定元件耦接感測裝置，以將感測裝置固定於使用者的待感測區域。
