I do.
温度測定効果をより良く実現するために、本発明の技術的解決手段では、前記温度センサはサーミスタ基板を含むサーミスタ温度センサであり、前記サーミスタ基板は、Ｂａ−Ｃｕ−Ｙ−Ｔｉ−Ｗ−Ｍｎ−Ｏに基づくコア・シェル構造のＰＴＣ感熱セラミック材料であり、具体的には、コア構造は（Ｂａ０．９８５Ｃｕ０．０１２Ｙ０．００３）（Ｔｉ０．９４Ｗ０．０３Ｍｎ０．０３）Ｏ３であり、シェル構造はＴｉＯ２である。 In order to better realize the temperature measurement effect, in the technical solution of the present invention, the temperature sensor is a thermistor temperature sensor including a thermistor substrate, and the thermistor substrate is Ba-Cu-Y-Ti-W-Mn. -O based core-shell PTC thermosensitive ceramic material, specifically, the core structure is (Ba 0.985 Cu 0.012 Y 0.003 ) (Ti 0.94 W 0.03 Mn 0. 03 ) O 3 and the shell structure is TiO 2 .
温度は基本的な物理量であり、現実に生活および生産における温度測定は非常に一般的になっている。温度センサは、温度を測定して温度の変化を使用可能な出力信号に変換するセンサである。温度センサは遍在しており、その中で、感熱材料は、温度の変化に非常に敏感な温度センサの中核となり、現在、多く応用されている感熱材料には、ＰＴＣ（正温度係数）感熱材料およびＮＴＣ（負温度係数）感熱材料が含まれる。正温度係数サーミスタは、キュリー温度付近での著しい抵抗変化のために電子産業の様々な分野で広く応用されており、現在最も多く生産されている感温素子である。現在、正温度係数感熱材料はチタン酸バリウムをベースとしており、その性能指数はさらに高める必要があり、さらに、この材料で作られた温度センサは厚くなり、その具体的な応用が制限される。現在の技術的解決手段では、チタン酸バリウム系サーミスタ材料は通常、Ｐｂ、Ｓｒ、Ｙ、Ｎｂなどの単一元素添加剤でキュリー点を移動し、半導体化を達成し、揚抗比を高め、そして高電圧耐性を高める。本出願の技術的解決手段では、コア・シェル構造を有するＢａ−Ｃｕ−Ｙ−Ｔｉ−Ｗ−Ｍｎ−Ｏ系ＰＴＣ感熱セラミック材料を革新的に採用し、シェル構造は、具体的には、高い導電率および抵抗温度特性を有するＴｉＯ２であり、それは内部のコア構造と組み合わせて機能し、サーミスタ基板の抵抗温度特性が改善され、予見できない技術的効果が得られる。さらに、コア・シェル構造の感熱セラミック材料を使用することによって、サーミスタ基板の厚さを効果的に低減し、温度センサを超薄型にし、適用範囲を拡大する。 Temperature is a fundamental physical quantity, and in practice temperature measurement in life and production has become very common. A temperature sensor is a sensor that measures temperature and converts a change in temperature into a usable output signal. Temperature sensors are ubiquitous, in which thermosensitive materials are the core of temperature sensors that are very sensitive to changes in temperature, and the most widely used thermosensitive materials today include PTC (Positive Temperature Coefficient) Materials and NTC (Negative Temperature Coefficient) thermal materials. Positive temperature coefficient thermistors have been widely applied in various fields of the electronics industry due to a remarkable resistance change near the Curie temperature, and are currently the most produced thermosensitive elements. At present, the positive temperature coefficient thermosensitive material is based on barium titanate, whose figure of merit needs to be further increased, and the temperature sensor made of this material becomes thicker, which limits its specific application. With current technical solutions, barium titanate-based thermistor materials usually move the Curie point with a single element additive such as Pb, Sr, Y, Nb, achieve semiconductivity, increase lift-drag ratio, Then, the high voltage resistance is increased. In the technical solution of the present application, a Ba-Cu-Y-Ti-W-Mn-O-based PTC thermosensitive ceramic material having a core-shell structure is innovatively adopted, and the shell structure is specifically, a high TiO2 having electrical conductivity and resistance temperature characteristics, which works in combination with the internal core structure, improves the resistance temperature characteristics of the thermistor substrate and provides unpredictable technical effects. In addition, the use of a core-shell structured thermo-sensitive ceramic material effectively reduces the thickness of the thermistor substrate, makes the temperature sensor ultra-thin, and extends its application range.
