- This contribution describes wireless IMU- and EMG-sensors for the control of Functional Electrical Stimulation that have been developed within the European project RETRAINER. Combined IMU- and EMG-sensors shall be integrated into the RETRAINER exoskeleton (S1 system) for estimation of the arm posture and for EMG-triggered stimulation. IMU-sensors shall be used within the RETRAINER hand neuroprosthesis (S2 system) to estimate the finger and hand motion. Both sensor types are Bluetooth 5 ready and incorporate a powerful Cortex M4F processor. Data preprocessing, like orientation estimation and adaptive linear prediction EMG filtering for estimating residual volitional muscle activity, can be implemented directly on the wireless sensors. This reduces the data rate significantly down to the stimulation frequency.
