Sensors-on-Paper: Fabrication of Graphite Thermal Sensor Arrays on Cellulose Paper for Large Area Temperature Mapping

This paper reports on a fabrication method to obtain multiple thermal sensors by employing an array of graphite thermocouple patterns on commonly available Xerox paper. The graphite thermocouples are patterned using two different grade graphite pencils, which show a stable and reproducible thermal sensitivity. The fabricated paper devices with multiple thermocouple arrays are capable of producing temperature mapping of the desired area. Different thermal conditions were applied to test and confirm the working of these devices. The present study shows that simple graphite trace patterns can convert a piece of paper into a thermal mapping device.

本研究报告了一种利用石墨热电偶阵列在常见的施乐纸上获得多个热传感器的制备方法。通过使用两种不同等级的石墨铅笔对石墨热电偶进行图案化处理，实现了稳定且可复制的热灵敏度。所制备的具有多个热电偶阵列的纸张设备能够生成所需区域的温度分布图。对不同的热条件进行了测试和验证，以确认这些设备的功能。当前研究揭示了简单的石墨轨迹图案可以将一张纸转换成为一种温度分布图设备。
