Flash memory 1GB on board Power supplied from USB or with lithium battery. Battery operating time 24h (using a Li-Ion 3.7V, 1000mAh, Fsamplig 10Hz ) Applications: Wearable Devices, Biomechanics, Gait Analysis and Rehabilitation, Instrumentation, Attitude and Heading Reference System, Scientific Research and Motion Analysis, at home rehabilitation General Description • EXLs2 is an inertial sensor based on MEMS technology and wireless communication ( Bluetooth™ 2.1 + Rx/Tx 868MHz ) made for motion measurement, acquisition and transmission. It features a complete IMU sensor set with full axis gyroscope, magnetometer, accelerometer, vibration motor, temperature sensor, audio output, long life battery, inductive battery charger, microphone, multi colors LED even for light up the enclosure. 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 in and outdoor ). 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 RX / TX 868 MHz radio allows to transmit the data at much greater distances than Bluetooth™. The built in Flash memory ( 1 GByte ) allows data logging over long period of activity. Data can then be retrieved by using Bluetooth ™ connection, 868 MHz transceiver or USB interface. Algorithms for motion characterization, statistical analysis, collision detection, orientation estimation, can be implemented on the on board 32 bit CPU ( Cortex M4 ). 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: info@exelmicroel.com www.exelmicroel.com
