foamin

Keisuke Watanabe +Ryosuke Yamamura +Yasuaki Kakehi


Soft sensors composed of deformable materials are expected to be applied to soft robots and computer interfaces. However, when conventional soft sensors are composed of only soft materials, the number of conductors increases and the wiring design becomes complicated. In this study, we propose "foamin", a soft sensor that is composed entirely of soft materials and can detect multimodal inputs with a single wire. The foamin consists of a single conductive foam and is capable of detecting multimodal deformation of the soft sensor due to the user's touch. This is realized by applying a multi-touch sensing technique called Swept Frequency Capacitive Sensing (SFCS) to detect the deformation of the soft conductive material.
