Three-dimensional surface printing method for interconnecting electrodes on opposite sides of substrates

Abstract As the application of the direct printing method becomes diversified, printing on substrates with non-flat surfaces is increasingly required. However, printing on three-dimensional surfaces suffers from a number of difficulties, which include ink flow due to gravity, and the connection of p...
