Researchers at the University of Maryland have created a new method to print corrosion-resistant copper circuits at temperatures between 100 and 150 degrees Celsius. By using a copper-organic composite, the team eliminated the need for expensive vacuum equipment and high-heat treatments that typically damage plastic substrates. This advancement allows high-conductivity circuits to be printed on heat-sensitive materials like paper and plastic films. The technology is expected to lower production costs for wearable sensors and flexible displays, expanding the reach of low-cost electronics.
