An Approach for Body Motion Registration Using Flexible Piezoelectret Sensors
Body motion registration can be applied to control computer interfaces or real devices, and force myography (FMG) is a promising modality to register real-time body motions. In this work, an approach for FMG recording was developed by using flexible piezoelectret sensors, and different lower-limb motions of three able-bodied subjects were captured. The experimental results demonstrated that the piezoelectret sensors were a suitable approach for FMG recording, and the five-channel data were possible to register the motions of leg raising, knee flexion, and knee extension. An average motion classification accuracy of 92.1% was achieved, which would be useful for the FMG-based device control in future work.
