Abstract: We live in an epoch of computerization for every field of life.Many researchers are hammering at the developments of the biomedical sensor that should be compact and should not force the wearer to leave the comfort zone.The cheaper and more comfortable human dynamics analysis devices with multi-sensor combinations, including force sensitive resistors, inclinometer, goniometers, gyroscopes and accelerometers, are continuously proposed for using in gait phases analysis and human dynamics analysis.The wearable sensor system we constructed uses a developed six-axis reaction force sensor to measure ground reaction forces during human walking and uses some inertial measurement units (gyroscope sensor and accelerometer) to collect data from the human motion of interest.We developed two prototypes of six-axis wearable force sensor with parallel mechanism to measure ground-reaction forces in human dynamics analysis.A parallel flexible mechanism was firstly designed for sensing impact forces and moments.Finite element method (FEM) was conducted for dimension optimization.Sensitivity of the load cells in the force sensor was improved by distributing strain gages on the maximum strain positions.A compact electrical hardware system
