Cover Story: Printable electronics (PE) allow for the low-cost and high-volume production of customized electronics devices, which makes PE appealing to a wide range of industries. However, for the fabrication of PE devices at an industrial scale, an in-line quality control tool has to be developed. Following the idea of a color control bar for traditional graphic art printing, we developed a quality control bar made from a terahertz vortex phase plate (VPP) that is able to follow the printed ink condition during production. We experimentally demonstrated by terahertz time-domain spectroscopy that the transmission response of VPP as a function of ink conductivity is consistent and more repeatable than conventional conductivity measurements, e.g., four-point probe. Our results open the door for a simple, non-destructive evaluation strategy for PE devices manufacturing in real-time and in a contactless fashion. View this paper.
