| Summary: | The use of prostheses is necessary to restore lost limbs to a level of functionality to enable activity of daily living.
Many prostheses are now using myoelectric based control techniques to operate. However, to develop a model
based controller for the system remains a challenge as accurate model is necessary. This study investigates the use
of electromyogram and ultrasound signal to predict thumb tip force based on Hill’s Muscle model. The results
obtained has shown a significant improvement in the prediction of thumb tip force as much as 31.45% of average
RMSE over the benchmark model that leverages on biomechanics model and active marker to characterize the
muscle |
