Battery operating time 3h (using a Li-Ion 3.7V, 160mAh, Fsamplig 10Hz ) GENERAL DESCRIPTION EXLs1 is an inertial sensor based on MEMS technology and wireless communication ( Bluetooth™ 2.1 ) made for motion measurement, acquisition and transmission. It features a complete IMU sensor set with full axis gyroscope, magnetometer, accelerometer, vibration sensor, temperature sensor. It is particularly suitable to be used in the medical field as a wearable devices for the body movements analysis ( posture assessment, rehabilitation, gait monitoring, joint’s biomechanics analysis, activity monitoring ). Other areas of application include multimedia interactions and vibration analysis. The Bluetooth™ radio allows standard interfacing to a wide range of devices ( PC, Tablets, Smartphone ) without the need of additional hardware so that data can be transmitted wirelessly up to 10 meters. The built in Flash memory ( 1 GByte ) allows data logging over long period of activity. Data can then be retrieved by using Bluetooth ™ connection or USB interface. Algorithms for motion characterization, statistical analysis, collision detection, orientation estimation, can be implemented on the on board 32 bit CPU ( Cortex M3 ). IMU hardware and software can be fully customized. EXEL s.r.l. via di Corticella 201, 40128 Bologna, Italy Tel. +39.051.6380211 Fax. +39.051.6380226 e-mail: [email protected] www.exelmicroel.com
