Please note: if recording at a sampling frequency of 1KHz is not vital within your study we recommend GENEActiv Original.
As part of our raw data actigraphy range, GENEActiv Action offers a unique recording sampling frequency of up to 1,000Hz. It is specifically designed for applications in performance measures such as professional sports, bone health and high impact activities, which demand wider range acceleration measurement and a higher sampling frequency.
- +/- 16g acceleration measurement at 7.8mg resolution
- 1KHz recording sampling frequency
- Over 12 hours of continuous recording
- Waterproof & robust
- Rechargeable battery
- Open source data format
Please note: specification is identical to that for the GENEActiv Original, with the exception of those items highlighted in orange below.
