CANCELLATION OF FORCE INDUCED ARTIFACTS IN SURFACE EMG USING FSR MEASUREMENTS
Repository Usage Stats
As multifunction prostheses become increasingly common, there is a need for improved control signal quality in order to control all the functions. Most signals commonly used for prosthesis control are sensitive to sweat, motion and external forces , which impairs prosthesis control performance. We have developed a prototype surface electromyogram (sEMG) sensor with three built‐in force sensing resistors (FSRs) for measuring the external forces, which may be used to cancel artifacts caused by these forces. The performance of the sensor as an estimator of muscle force is presented in this paper. The sEMG and FSR signals have also been tested individually, as a reference for the performance using the combination of these signals.
