The Flexible Interface Using a Stretch Sensor

AbstractIn this paper, we propose a stretch sensor for application to flexible interface. This sensor is extremely thin, lightweight and sensitivity. It has three elastomer layers. Middle and bottom layers have electrodes that are mainly made from conductive particles. Since this sensor is thin and stretchable, it can be easily attached to various types of objects such as input devices and different parts of the body without altering the original shape of the object. It can also present capacitance in accordance with the amount of area expanded. We tested this sensor to measure the sensor's capacitance on the elbow and the elbow's angle. It was confirmed that the capacitance of the stretch sensor changes was coincided with the elbow's angle measured. Applications illustrated the utility of this stretch sensor. In the future, this sensor is expected to realize a wide range of technologies, such as human interfaces, smart clothes
