Printed electronics represents an enormous potential in a world of interconnected appliances. But there is still a large gap between the technology that is available and the potential for real-life applications. “That’s why we are focusing so strongly on intensive collaboration with our customers,” says Wim Christiaens, R&D director at Quad Industries.
