Abstract: A sock for capturing motion data of a user includes (i) a sock enclosure having a calf portion, a shin portion, and a foot portion, and (ii) one or more sensors, wherein each sensor is disposed within a biosignal channel in the sock enclosure. The sock includes an electronic pad disposed adjacent to the shin portion. The electronic pad includes a flexible printed circuit board on which the one or more sensors are embedded, a processor configured to receive motion data generated by the one or more sensors, and a power supply device configured to power the one or more sensors. The sock includes an insole layer disposed along the foot portion and communicatively connected to the electronic pad. The sock and an external computing device form a motion analytics system, wherein the external computing device performs a data analytics method to provide context and insight to the user.
