The development of flexible and transparent devices requires completely transparent and flexible circuits (TFCs). To overcome the disadvantages of the previously reported TFCs that are partially transparent, lacking pattern control, or labor consuming, we achieve true TFCs via a facile process with precise pattern control, exhibiting concurrent high transparency, conductivity, flexibility, stretchability, and robustness. A highly transparent and flexible conductive film is first made through spin coating silver nanowires (AgNWs) onto polydimethylsiloxane (PDMS), and demonstrates simultaneous high transparency (90.86%) and low sheet resistance (3.22 Ω sq⁻¹). Taking advantage of microfluidic technology, circuits with ultraprecise and complex patterns from the microscale to milliscale are obtained through spin coating of AgNWs into microfluidic channels on PDMS. Without elaborate processing, this method may be suitable for mass production, which would contribute enormously to potential applications in wearable medical equipment and transparent electronic devices.

通过将银纳米线构图成微流体通道，实现高度透明和灵活的电路†

柔性和透明设备的开发需要完全透明和柔性的电路（TFC）。为了克服先前报告的TFC的部分透明，缺乏图案控制或劳动力消耗的缺点，我们通过具有精确图案控制的简便过程来实现真正的TFC ，同时显示出高透明度，导电性，柔韧性，可拉伸性和坚固性。首先通过将银纳米线（AgNWs）旋涂到聚二甲基硅氧烷（PDMS）上来制作高透明度和柔性的导电膜，该膜同时具有高透明度（90.86％）和低薄层电阻（3.22Ωsq ^-1））。利用微流体技术，通过将AgNWs旋涂到PDMS上的微流体通道中，可以得到从微米级到毫米级具有超高精度和复杂图案的电路。如果不进行复杂的处理，此方法可能适合于批量生产，这将极大地促进可穿戴医疗设备和透明电子设备中的潜在应用。
