Biosensor device and physiological monitor

A physiological monitor, comprising:

• a biosensor device, comprising:
• a flexible base comprising a first side and a second side that are opposite to each other;
• a first sensor comprising a first sensor body, wherein the first sensor body is mounted at the first side of the flexible base;
• and
• a second sensor comprising a second sensor body, wherein the second sensor body is detachably mounted at the first side of the flexible base at which the first sensor body is provided, and is spaced apart from the first sensor body, if the second sensor is mounted on the flexible base, the first and second sensors are capable of being used together to measure different physiological parameters of a same patient, and if the second sensor is detached from the flexible base, the first and second sensors are capable of being used separately to measure different physiological parameters of different patients;
• a signal processing device;
• and
• a monitor, wherein the signal processing device is connected between the biosensor device and the monitor or is integrated into the monitor.
