Engineers have used laser-treatment process that allows them to use printed graphene for electric circuits and electrodes – even on paper and other fragile surfaces. The technology could lead to many real-world, low-cost applications for printed graphene electronics, including sensors, fuel cells and medical devices. Previous technology meant that graphene had to be treated to improve electrical conductivity and device performance. That usually meant high temperatures or chemicals – both could degrade flexible or disposable printing surfaces such as plastic films or even paper.
Das PhD and assistant/Prof Claussen came up with the idea of using lase...
