Abstract

Sustainability is becoming an increasingly crucial focus across various industries, reigniting interest in wood as a material. To enable its broader utility and smart applications, the integration of electronics and sensors into wooden surfaces is essential. Yet, preserving the optical integrity of elegant wood finishes is of paramount importance. This article presents the realization of a transparent touch sensor on recon veneers. The touch sensor relies on an interdigital capacitor (IDC), screen-printed using silver nanowire ink. Applying a protective coating onto the sensor prevents responses to ambient humidity. The temperature dependence of the sensor signal exhibits a contrasting trend compared to the touch response. The sensor demonstrates the highest touch sensitivity at a frequency of 2.57 MHz. A standard deviation of 0.7% was found, highlighting the sensor’s precision. This research paves the way for seamlessly incorporating advanced electronics into wooden surfaces while maintaining their aesthetic appeal and functionality.

木质透明触摸传感器：兼顾美学的可持续发展

可持续发展日益成为各行各业关注的焦点，重新激发了人们对木材这种材料的兴趣。为了使木材具有更广泛的实用性和智能应用，必须将电子设备和传感器集成到木材表面。然而，保持优雅木质饰面的光学完整性至关重要。本文介绍了在重组木皮上实现透明触摸传感器的方法。该触摸传感器依靠的是使用银纳米线油墨丝网印刷的数字间电容器（IDC）。传感器上的保护涂层可防止对环境湿度产生反应。与触摸响应相比，传感器信号的温度依赖性呈现出截然不同的趋势。传感器在频率为 2.57 MHz 时的触摸灵敏度最高。标准偏差为 0.7%，突出了传感器的精确性。这项研究为将先进的电子技术无缝融入木质表面，同时保持其美观性和功能性铺平了道路。
