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

该项目的主要目标是在竞争前开发一种便携式和可穿戴的动态监测和辅助系统，该系统使用分布式无线MARG（磁、角速率、重力）传感器。作为一种诊断程序、慢性病的早期发现或最佳维持，或在外科手术或中风等急性事件的康复期间，许多患者都可以从持续监测中受益。拟议的系统将包括一个定制开发的微型和无系绳MARG传感器网络，称为无线惯性传感器包（WISPs），它将专门用于以分布式方式捕获人体各部分的动态运动。分布式wisp可以连接到患者的一组相互连接的身体部位（例如上肢，下肢或整个身体），并协同提供其运动学的实时测量。这种真正的动态运动跟踪系统的潜在影响是巨大的，它开启了对现场患者进行长时间连续监测的可能性。

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.
