High sensitivity temperature sensor

Abstract

The invention discloses a high sensitivity temperature sensor. The sensor is characterized by comprising a magnesium fluoride substrate and a magnesium fluoride film, wherein, an annular micro-resonant cavity structure which is formed by utilizing a polymer micro-nano optical fiber is arranged on the magnesium fluoride substrate, one end of the annular micro-resonant cavity is connected with a standard optical fiber input end by the conical transition zone of a monox micro-nano optical fiber, and the other end is connected with a standard optical fiber output end by the conical transition zone of another monox micro-nano optical fiber; and the annular micro-resonant cavity adopts the mode of evanescent wave coupling to realize light input and output, and the magnesium fluoride film covers the above mentioned components, and fixes and seals the components on the magnesium fluoride substrate. The high sensitivity temperature sensor is a temperature sensor based on the annular resonant cavity of a subwavelength-diameter polymer micro-nano optical fiber, overcomes the defects of the prior art, and has the advantages of high sensitivity and response speed.

AI Technical Summary

Benefits of technology

This invention relates to improving the performance or accuracy of an optoacoustic device by combining it into one component called a micrometer (μm)-Nanometer diameter fibers ring. By adding this special material onto these rings during production, we can improve their properties such as measurability, responsiveness, and resolution capabilities for various applications like medical imaging devices.

Problems solved by technology

This patented technical solution describes an improved way to make accurate temperature detection without requiring complicated components like optoacoussis devices (OA). Optically active polymeric molecules called thermochroics can provide strong antireflection properties when exposed to specific temperatures. These techniques allow for faster responses than previous methods due to their compact design and fast response time. Additionally, these novel types of material systems offer potential benefits over traditional ones including better durability against environmental factors like heat stress and electrostatic interferences.
