Fundamental Study of Sensing Technique Utilizing Magnetic Compound Fluid Rubber Sensor under Radiation Environment

Abstract

Magnetic compound fluid (MCF) rubber can be used to construct a self-sensing smart sensor because it has a self- induced voltage that is changed by normal and shear forces. MCF rubber is flexible and elastic, and can thus be incorporated into a wide variety of devices, such as haptic sensors, capacitors, and solar cells. We thus plan to install MCF rubber on a robot to examine a radiation environment such as a nuclear power plant. Here, we conduct a fundamental study of a sensing technique that utilizes MCF rubber in a radiation environment. We clarify the irradiation effect on an MCF rubber sensor at an irradiation facility. The results show that MCF rubber installed on a robot can effectively sense radiation.
