Abstract

Development of paper-based sensors that do not suffer with humidity interference is desirable for practical environmental applications. In this work, a laser processing method was reported to effectively modulate the cross-sensitivity to humidity of ZnO-based UV (Ultraviolet) sensors printed on paper substrate. The results reveal that the laser induced zinc oxide (ZnO) surface morphology contributes to the super-hydrophobicity of the printed ZnO nanoparticles, reducing humidity interference while enhancing UV sensitivity. Herein, this conducted research highlights for the first time that laser processing is an attractive choice that reduces the cross-sensitivity to water vapor in the UV sensing response of ZnO-based devices printed on paper, paving the way to low-cost and sophisticated paper-based sensors.

摘要

开发不受湿度干扰的纸质传感器对于实际环境应用来说是很有必要的。在这项工作中，报道了一种激光加工方法，该方法能有效调节印刷在纸质基板上的基于氧化锌（ZnO）的紫外线（UV）传感器对湿度的交叉敏感性。结果表明，激光诱导的氧化锌（ZnO）表面形态有助于印刷的ZnO纳米颗粒的超疏水性，在提高紫外线灵敏度的同时降低湿度干扰。在此，本研究首次强调激光加工是一种有吸引力的选择，它能降低印刷在纸上的基于ZnO的器件在紫外线传感响应中对水蒸气的交叉敏感性，为低成本且精密的纸质传感器铺平了道路。
