A physiological sensor device, a correction method, and a wearable device are provided. The physiological sensor device includes a physiological signal sensor, a first compensation sensor, and a signal processing device. The physiological signal sensor is attached to the object to be measured to sense a physiological signal value. The first compensation sensor is disposed on the physiological signal sensor. The signal processing device is coupled to the physiological sensor device and the first compensation sensor. The signal processing device obtains a first failure area of the physiological signal sensor partially separating from the object to be measured by the first compensation sensor, obtains a first failure compensation value according to the first failure area, so as to compensate the physiological signal value sensed by the physiological signal sensor.一種生理感測器裝置及系統、校正方法及穿戴式裝置。生理感測器裝置包括生理訊號感測器、第一補償感測器以及訊號處理裝置。生理訊號感測器貼附於待測物以感測生理訊號值。第一補償感測器配置於生理訊號感測器。訊號處理裝置耦接生理訊號感測器和第一補償感測器。訊號處理裝置藉由第一補償感測器獲得生理訊號感測器從待測物部分脫落的失效區域，並依據失效區域獲得第一失效補償值，以對由生理訊號感測器所感測的生理訊號值進行補償。
