可伸缩电子传感设备正在定义可穿戴电子产品的发展方向。在娱乐、健康监测和医疗保健领域的潜在应用中，需要附着在衣服或人体皮肤上的高性能柔性应变传感器。在这项工作中，通过集成激光直写和转移印刷方法，在聚二甲基硅氧烷上制作导电铜电极作为敏感的可拉伸微传感器。铜电极是用激光书写从铜盐中还原出来的，而不是用预合成的铜或氧化铜纳米颗粒印刷的一般方法。在40 μm厚的Cu电极上，电阻率可达96 μΩ cm。运动感应功能成功地证明了高灵敏度和机械鲁棒性。这种原位制造方法通向柔性衬底上的电子器件。
Stretchable electronic sensing devices are defining the path toward wearable electronics. High-performance flexible strain sensors attached on clothing or human skin are required for potential applications in the entertainment, health monitoring, and medical care sectors. In this work, conducting copper electrodes were fabricated on polydimethylsiloxane as sensitive stretchable microsensors by integrating laser direct writing and transfer printing approaches. The copper electrode was reduced from copper salt using laser writing rather than the general approach of printing with pre-synthesized copper or copper oxide nanoparticles. An electrical resistivity of 96 μΩ cm was achieved on 40-μm-thick Cu electrodes on flexible substrates. The motion sensing functionality successfully demonstrated a high sensitivity and mechanical robustness. This in situ fabrication method leads to a path toward electronic devices on flexible substrates.
