Inexpensive, wearable, wireless, multi-channel, and multi-sensor data acquisition system
Alexander Reyes, Francisco J. Valero‐Cuevas · 2013
In this paper, we discuss a wearable wireless system capable of acquiring data from a variety of sensors. The device uses Bluetooth technology to stream data from up to 16 channels/sensors to a laptop computer running MATLAB. Complete with programmable sampling rates, off-the-shelf components, and power saving features, this system provides an inexpensive and reliable means of transmitting data for collection and processing. Currently, this device has been used in clinical applications to collect force data during dexterous manipulation and to drive interactive computer games, in outdoor environments to collect 3D accelerometer data to analyze human movement during slack line walking, and in the sports setting to measure limb and trunk accelerations from individuals recovering from ACL injuries.
