Printed electronics is a promising, environmentally friendly alternative to producing flexible display or energy products at a low cost and high volumes.
Terahertz light, an invisible cousin of infrared light, has unique sensitivity to material properties and enables fast, non-destructive quality inspection of printed structures.
Quality control bars (QCBs) are based on metamaterial design and print simultaneously alongside commercial products.
QCBs can be designed to detect specific features such as ink conductivity, spreading, and thickness, and can be customized for any ink, press type, or web size.
