1. A system configured to monitor and characterize motions of a user, the system comprising:
a wearable article configured to be worn by the user, the wearable article comprising:
a tubular body comprising a resilient material;
a flexible circuit coupled with the tubular body, the flexible circuit comprising a fluid-phase conductor configured to generate a first signal; and
an inertial measurement unit (“IMU”) coupled to the resilient material, wherein the IMU is configured to generate a second signal; and
a processor communicably coupled to the flexible circuit and the IMU, wherein the processor is configured to:
receive the first signal from the flexible circuit and the second signal from the IMU;
determine a first electrical parameter associated with the flexible circuit based on the first signal;
determine a second electrical parameter associated with the IMU based on the second signal;
correlate the first electrical parameter to a first physical parameter associated with the flexible circuit and the second electrical parameter to a second physical parameter associated with the IMU; and
generate a virtual model of a joint or appendage of the user wearing the wearable article;
determine a real-time position of the joint of the user based on the correlation; and
display, via a display, the virtual model of the joint or appendage in a virtual position that is representative of the real-time position.
