Recording Raw Tri-Axial Acceleration with the Actiwave Motion
IMPORTANT! - in the EU, the Actiwave is indicated for research use only and is not intended for clinical use.
The Actiwave Motion is a dedicated ambulatory raw acceleration logging device. Using the latest tri-axial MEMs accelerometer technology, 3 axis recordings of raw acceleration may be made for up to 7 days (25Hz sampling). The setup offers the options of between 25 Hz sampling to 100 Hz sampling for more detailed capture of activities over shorter periods.
The Actiwave Motion records acceleration only - no electrodes are required.
The device weighs only 5.6 grams and is 25 x 27 x 8.5 mm making the device small enough for ambulatory conditions and discrete enough to have the lowest possible impact on patient burden. The very small size and weight of these units makes them ideal for paediatric and veterinary use.
A dedicated quick release mounting may be optionally used with a choice of adjustable soft elastic mounting straps to allow positioning on the waist, arm, thigh, ankle or any other suitable location on the body.
The device is first placed inside the mounting 'boot':
The mounting strap may then be adjusted and attached to the device with the quick release hooks:
Acceleration recordings can be saved as EDF+ as for the rest of the Actiwave range, or CSV for maximum ease of access to the raw data.
