Surface electromyograms (sEMG) contain artifacts induced by e.g. sweat, motion and external forces. These artifacts are undesirable because they impair the performance of prosthesis control systems. 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.
