| Research Abstract |
In this research, we conducted a fundamental research to develop a flexible contact sensor system capable of reliable detection performance over a wide-range area, which uses a viscoelastic tube and an ultrasonic signal propagating through it. We revealed the propagation characteristics of the ultrasonic signal in a straight and curved tube, and proposed a method that produces monitoring signals used in a self-diagnosis circuit for a voluntary tube shape. A self-diagnosis algorithm that can detect an abnormal state of the sensor system including sensor failures has developed and confirmed its validity experimentally.
