This study presents a new fabrication method for touch screen sensors using inexpensive, flexible, and transparent polyethylene terephthalate (PET) films. In the proposed method, a transparent capacitive touch sensor array is implemented with two independent axes of invisible electrodes consisting of indium tin oxide (ITO) patterns and bridge electrodes. A low‐cost implementation of the bridge electrodes is achieved by using near‐field electrospinning (NFES) method for the conductive lines with linewidth of 3–5 µm. Then, the printed bridge electrode is sintered using green laser without damaging the PET film. It is demonstrated that two transparent electrodes deposited on a single sheet of PET film can detect the touch location by scanning the driving signal while simultaneously measuring the capacitances from the sensing lines connected via bridge electrodes.

薄，柔性和透明触摸屏传感器的低成本制造方法

这项研究提出了一种新的制造触摸屏传感器的方法，该方法使用廉价，柔性和透明的聚对苯二甲酸乙二醇酯（PET）薄膜。在所提出的方法中，透明的电容式触摸传感器阵列由两个独立的不可见电极轴组成，该不可见电极由铟锡氧化物（ITO）图案和桥电极组成。通过对线宽为3–5 µm的导线使用近场静电纺丝（NFES）方法，可以实现桥电极的低成本实现。然后，使用绿色激光烧结印刷的桥接电极而不损坏PET膜。
