    • Provided are an interdigitated electrode (IDE) for an electronic device, which includes a plurality of anodes and a plurality of cathodes arranged radially in an alternating fashion for electrical insulation from one another, and an electronic device using the same. The IDE in which the anodes and the cathodes are arranged radially in an alternating fashion is fabricated and applied to the electronic device, so that the entire fabrication process can be simplified compared to that of a typical electronic device in which an upper electrode is different from a lower electrode. Also, circular or polygonal IDEs can be applied to systems that are driven or measure values on their central axes, thereby enhancing the performance and efficiency of the systems. Furthermore, the circular or polygonal IDEs can be employed in systems such as acoustic sensors, pressure sensors, micro-speakers, biological sensors, and acceleration sensors, so that the structure and operation of the systems can be simplified.
