2P2-E05 Development of a Wearable Ground Reaction Force Sensor Device : Structural Analysis for the Lighter Device(Welfare Robotics and Mechatronics(2))

Abstract

The measurement of ground reaction forces (GRF) and zero moment points (ZMP) is important in gait analysis. We have developed a wearable ground reaction force sensor device to measure GRF and ZMP by using very thin (about 0.2mm) flexible tactile sensors. In this paper, first, we design the lighter sensor device by using the finite element method, in order to make the sensor device lighter. Second, we develop the lighter sensor device. Finally, we experimentally examine the usefulness of the developed sensor device.
