Item Open Access Multimodal Input Device With SEMG And Contact Force Sensors(2011) Stavdahl, Øyvind; Kyberd, Peter J.; Magne, Tordis; Ottermo, Maria V.; Mugaas, TerjeIn myoelectric prostheses, movement artifacts are known to impair control performance. This study relates to a novel sensor which measures surface electromyograms (SEMG) as well as contact force at the electrode-skin interface. Its purpose is to explore the in-socket mechanical realities of movement artifacts in order to produce control algorithms that are more robust to said artifacts. The new sensor includes a commercial SEMG electrode and four surface-mounted force sensors, stacked within a plastic housing. Preliminary experiments in an experienced transradial user showed that sudden lack of control was often caused by electrode lift-off or re-connection. Future work will include algorithms for alleviating these problems.
