Abstract

In this study, a miniaturized thermistor sensor was produced using the Aerosol Jet printing process for temperature sensing applications. A nickel oxide nanoparticle ink with a large temperature coefficient of resistance was fabricated. The thermistor was printed with a circular NiO thin film in between the two parallel silver conductive tracks on a cutting tool insert. The printed thermistor, which has an adjustable dimension with a submillimeter scale, operates over a range of 30-250 °C sensitively (B value of ~4310 K) without hysteretic effects. Moreover, the thermistor may be printed on a 3D surface through the Aerosol Jet printing process, which has increased capability for wide temperature-sensing applications.

摘要

在本研究中，采用气溶胶喷射印刷工艺制造了一种用于温度传感应用的小型热敏电阻传感器。制备了一种具有大电阻温度系数的氧化镍纳米颗粒墨水。在切削刀具刀片上的两条平行银导电轨道之间，用圆形NiO薄膜印刷热敏电阻。印刷的热敏电阻尺寸可在亚毫米尺度上调节，在30-250°C范围内灵敏地工作（B值约为4310 K），无滞后效应。此外，通过气溶胶喷射印刷工艺，热敏电阻可以印刷在三维表面上，这增加了其在宽温度传感应用中的能力。
