Abstract

This study describes the development of a novel wearable device that is capable of altering the wearer's inertia through the use of the gyroscopic effect. When an angular velocity in the upper body is given, the device generates a twisting moment alone the body. We describe the working principle of the wearable gyroscopic device and its feasibility in several posture control applications. Further experiments were also performed using a force plate and a motion capture system in order to find the effect of the gyroscopic moment on the body. We could observe the change in the rotational angle of the body in the trunk yaw axis and the center of gravity of the body. Potential applications of the developed device include postural control and the human body fall prevention.
