Cut-and-paste customization of organic FET integrated circuit and its application to electronic artificial skin

The concept of cut-and-paste customization is introduced for the first time in designing integrated circuits based on mechanically flexible organic field-effect transistors, and is applied to electronic artificial skin. The electronic artificial skin comprise of three separate integrated circuits that are a pressure-sensor array, row decoders, and column selectors to read out pressure information over a large area. All of three integrated circuits are scalable in size because the pressure-sensor array is a simple repetition of sensor cells and the row and column decoders adopt wired-NAND circuits, which enables the cut-and-paste customization in size. The physical cut-and-paste procedure is employed by cutting a part of the integrated circuits and pasting it to another integrated circuit with a connecting plastic tape. The integrated circuits are designed with a standard SPICE simulator and layout design tool, and the operation is confirmed by measurement.
