Wagyromag: Wireless sensor network for monitoring and processing human body movement in healthcare applications

Human body movement can be monitored through a wireless network composed of inertial sensors. This work presents the development of Wagyromag (Wireless Accelerometer, GYROscope and MAGnetometer), a wireless Inertial Measurement Unit (IMU) composed of a triaxial accelerometer, gyroscope and magnetometer. Communication is based on a 802.15.4 network. Furthermore, calibration, signal conditioning and signal processing algorithms are presented throughout this work. Wagyromag’s high potential permits its application in a wide range of medical applications such as telerehabilitation, nocturnal epilepsy seizure detection, fall detection and other applications in the field of sport science. 2011 Elsevier B.V.
