General description

EXL-s1 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 GB) 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.
