Fatigue detection device, support system, and method for operating the fatigue detection device

Abstract

To provide a fatigue detection device capable of accurately detecting a fatigue of an object tissue by non-invasive means, a supporting system with the fatigue detection device, and a fatigue detection method.SOLUTION: The fatigue detection device comprises: an ultrasonic device which transmits ultrasonic waves to the inside of a living body and receives the ultrasonic waves reflected by a tissue inside the living body, and outputs a reception signal; and one or more processors. The processors acquire the reception signal output from the ultrasonic device and detect a fatigue state of the tissue on the basis of variation in the reception signal when a load is applied to the living body.SELECTED DRAWING: Figure 1
