The emergence of soft robots with “flexible motion” is expected to be improved by incorporating flexible energy harvesting technology and electronic devices with excellent biocompatibility. Therefore, it is important to improve the design and performance of the device itself, according to the soft adherend to which the device is applied. In this study, we outline the design of flexible devices from a mechanical viewpoint and introduce our recent achievements.
