Future smart homes could be powered with electronics built on stones

Posted On: 2022-09-02

Stones, such as marble and granite, are natural, eco-friendly materials that many people building or renovating houses already use. Now, in a step toward integrating energy storage with these materials, researchers have fabricated microsupercapacitors onto the surface of stone tiles. Researchers patterned a copper oxide nanoparticle solution on a marble tile and pointed a near-infrared laser on the nanoparticles, producing pure copper electrodes that were porous, highly conductive and strongly attached to the stone's surface.
