GENEActiv Sleep are made-to-order; please contact us for further details.
Please note: if direct skin temperature recordings are not vital within your study we recommend GENEActiv Original.
GENEActiv Sleep is a simple, reliable and cost-effective wrist-worn behavioural device used to research sleep interdependencies with health and lifestyle factors, improving sleep diagnosis. Specified for the monitoring of circadian rhythm, this variant allows the direct and continuous recording of skin temperature at any body location.
- Stainless steel temperature plate
- Splash proof
- Open source data format
As well as standard sleep actigraphy outputs, the raw data format allows many further analysis possibilities, for example:
- Full lifestyle & sleep assessment
- Position & tremor analysis
- Frequency domain analytics
Please note: specification is identical to that for the GENEActiv Original, with the exception of those items highlighted in orange below.
