http://www.freescale.com/kinetischallenge - The Make It Challenge featuring Kinetis MCUs is Freescale's latest design contest. Using technologies, including the Kinetis K53 MCU, TWR-K53 tower board, electrocardiograph development kit (MED-EKG), Freescale network starter kit (1322xNSK-DBG development kit), and Beekit Software. ZIMUED is a ZigBee architecture-based wearable sensor for biomechanical analysis, and it's an innovation tool for online monitoring of rehabilitation therapy. These sensor nodes will allow measurement of a patient s kinematic and the three-dimensional orientation in order to evaluate the specific muscle activations through human models. To estimate the muscular power evolution, the EMG sensor measures the electrical activity of each muscle involved. The Kinetis K53 MCU calculates the three-dimensional orientation data from three-axis sensors such as an accelerometer, a gyroscope and a magnetometer through the Direction Cosine Matrix algorithm, including sensor drift and noise detection with a proportional integral correction. The powerful analog measurement engine and the DSP features of the Kinetis K53 MCU allow the correct processing of the EMG signals, such as an integrated instrumentation amplifiers, baseline digital control and FIR band-pass and notch filter. The ZIMUED target market includes medical institutions or any injured individual. Its purpose is improving patient's wellness and comfort by reducing the time in rehabilitation centers and providing new home care solutions.
