Abstract: A mobility augmentation system assists a user's movement by determining a corresponding electrical stimulation for the movement. A wearable stimulation array includes sensors, electrodes, an electrode multiplexer, and a controller that executes the mobility augmentation system. The sensors measure movement data, and the mobility augmentation system applies a movement model to the measured movement data. The model can determine different electrical actuation instructions depending on the movement stimulated. For example, to stimulate a knee flexion, the movement model output enables a first set of the electrodes to operate as cathodes and a second set of electrodes to operate as anodes. To stimulate a knee extension, the first set of electrodes can be enabled to operate as anodes and a third set of electrodes as cathodes. The user can provide feedback of the applied stimulation, which the system can use to retrain the model and optimize the stimulation to the user.

Abstract: Disclosed herein are methods, devices, and media for determining physiological characteristics. In some embodiments, a method involves obtaining an electromyography (EMG) signal representing muscle activity from an EMG electrode disposed in or on a band of a wrist-worn device, and a photoplethysmography (PPG) signal using a PPG sensor of the wrist-worn device. The method may involve generating a modified PPG signal using the EMG signal, wherein the modified PPG signal corrects for motion artifacts in the PPG signal due to motion activity of a wearer of the wrist-worn device. The method may involve determining at least one physiological characteristic based on the modified PPG signal.
