Stretchable Electronic Devices realized by Rigid Materials with Good Electrical Properties

Abstract

Recently, flexible/stretchable electronic devices, such as flexible sensor, display, and solar cell, has attracted much attention. To achieve such a flexible/stretchable electronic device, many researchers have used organic materials, such as organic light-emitting diodes (OLEDs), organic transistors, and organic electrodes (e.g. PEDOT:PSS). As compared with metal or semiconductor materials, organic materials might have good properties for mechanical deformation, however, the electrical properties are usually poor. Therefore, we focused on achieving “flexible/stretchable” electronic devices using “rigid” materials/components with good electrical properties. In this paper, as research based on this idea, we introduce research on “self-healing metal interconnect” as an interconnect for stretchable electronic devices and research on “origami/kirigami structures” for stretchable electronic devices.
