Development of a distributed wireless motion tracking system for ambulatory monitoring of human body segment movement

The main goal of this proposed project is the pre-competitive development of a portable and wearable ambulatory monitoring and assistive system using distributed wireless MARG (Magnetic, Angular Rate, Gravity) sensors. Many patients can benefit from continuous monitoring as a diagnostic procedure, early detection or optimal maintenance of a chronic condition, or during rehabilitation from a surgical procedure or an acute event such as stroke. The proposed system will consist of a network of custom-developed miniature and untethered MARG sensors, called Wireless Inertial Sensor Packages (WISPs), which will be specifically designed for the task of capturing the ambulatory movements of human body segments in a distributed fashion. The distributed WISPs can be attached to a set of interconnecting body segments (e.g. upper limb, lower limb, or entire body) of a patient, and cooperatively provide the real-time measurements of their kinematics. The potential impact of such a truly ambulatory motion tracking system is enormous, opening the possibility of continuous monitoring of patients on-field, over extended periods of time.
