SENSING SYSTEM USING POSITIVE FEEDBACK

Title:

SENSING SYSTEM USING POSITIVE FEEDBACK

Document Type and Number:

WIPO Patent Application WO/2015/065024

Kind Code:

A1

Abstract:

According to the present embodiment, a sensing system comprises: an optical actuator for applying optical stimulation to a sensing material; a non-photo detector for outputting a snapback-type electrical signal corresponding to a non-photo reaction formed depending on the characteristics of a medium to which the optical stimulation is applied; an amplifier for amplifying the electrical signal output by the non-photo detector and for applying the amplified electrical signal to the optical actuator by employing positive feedback; and an output unit for receiving the electrical signal and detecting the characteristics of the medium.
