hand glove

The developed system consists of a hand motion capture device based on resistive flex sensors and an Inertial Measurement Unit (IMU), designed for motor rehabilitation and functional validation of hand prostheses. The operating principle is based on detecting the angular deformation of the fingers using flex sensors, whose resistive variation is proportional to the degree of curvature. This analog signal is conditioned and digitized for subsequent processing. Additionally, an IMU is integrated to estimate the spatial orientation and dynamics of the hand-wrist segment, allowing for the acquisition of three-dimensional movement data. The acquired data is transmitted to a simulation environment developed in Unity, where the movement is virtually represented, facilitating interactive rehabilitation processes and verification of the mechanical performance of prostheses.
