Title:
TEMPERATURE SENSOR BASED ON SURFACE PLASMA RESONANCE AND PRODUCTION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/080049
Kind Code:
A1
Abstract:
The invention discloses a temperature sensor based on surface plasma resonance and a production method thereof. The temperature sensor comprises: a light source transmitter (10), a sensing device (20) and a spectrograph (30). An output end of the light source transmitter (10) is connected with an input end of the sensing device (20). An output end of the sensing device (20) is connected with the input end of the spectrograph (30). The sensing device (20) comprises a side-polished single-mode optical fiber (201), a gold film (202) and a temperature-sensitive thin film (203). The gold film (202) is deposited on a polished side of the side-polished single-mode optical fiber (201), and the temperature-sensitive thin film (203) is solidified on the gold film (202). With the fact that the solid temperature-sensitive thin film (203) is solidified on the gold film (202), and because the solid temperature-sensitive thin film (203) does not have the flow ability as that of a liquid material, the liquid encapsulation procedure in the prior art is omitted, and the production process is simplified; in addition, due to the fact that the solid temperature-sensitive thin film (203) is solid and is not evident in thermal expansion effect, device structure stability is increased, and application of the temperature sensor in fields such as biochemistry is not limited. Also disclosed is a method for preparing the temperature sensor.
