The ground reaction force (GRF) is one of the important factors to clarify biomechanics, and a force plate (FP) is widely used to measure GRF. This paper describes a quad-axis FP that uses mechanical springs and four non-contact displacement sensors. It is expected that the shape and performance of the proposed FP can be easily adjusted. When the force is applied to the FP, the deformations of the springs are measured by four non-contact displacement sensors. The magnitude and direction of forces and moments can be evaluated from the responses of the four sensors. The FP resonance frequency was 123 Hz, sufficient for the GRF measurement. The calibration experiments showed that vertical and horizontal forces and moments could be measured independently. As a result, the proposed FP measured the GRF in four directions during walking.
