Inkjet Printing Next-Generation Three-Dimensional Touch Device

Touch-sensitive devices are an integral part of our daily lives. Central to these devices are "crossbar arrays," which are electrical components capable of accurately pinpointing the touch location. It is complicated to design such arrays, often requiring various components such as multiple electrodes, which facilitate the flow of electric current within the device circuit. Is there a simpler alternative to this ubiquitous technology? Addressing this question, a research team led by Professor Wooyoung Shim from the Department of Materials Science and Engineering has now developed a simplified touch-sensor device with only two electrodes.
