<p>Based on an XYZ coordinate system, a piezoelectric fiber composite material structure of the present invention is configured to arrange each piezoelectric fiber on at least two axes, detect an external force acting on a Z axis as a vertical component of the XYZ coordinate system from the one axis among the two axes, and detects an external force acting on an X coordinate or a Y coordinate as a horizontal component of the XYZ coordinate system from the other one axis among the two axes, wherein the piezoelectric fiber is surrounded by a protector body (1, 10, 20) protecting the inside thereof from outside environment. Therefore, ground contact pressure and ground friction acting on the two axes, respectively are detected at the same time. Specifically, the accuracy and reliability of the force measured individually are improved by optimizing the arrangement direction of the piezoelectric fiber in the two axes with various methods.</p> |
