Abstract

Disclosed is a sensing system including an actuator configured to provide a stimulus to a detection-target material, a photo-detector configured to output an electrical signal having a snapback (SB) form corresponding to an optical reaction brought about according to the concentration of the detection-target material to which the stimulus has been provided, an amplifier configured to amplify the electrical signal output from the photo-detector and positively feedback and apply the amplified electrical signal to the actuator, a detector configured to receive the electrical signal and detect the detection-target material, and a voltage clamping device connected in parallel with the photo-detector and configured to clamp a voltage at both ends of the photo-detector so that the voltage does not exceed a predetermined voltage value.
