Ultra-miniature Veterinary Actigraphy


Collar Mounting, Ultra-miniature Veterinary Actigraph…


Incredibly Small, Lightweight and Waterproof Veterinary Actigraph…


Bluetooth LE5 set-up and download, USB charging with NanoDock…

The Nano is an all-new, ultra-miniature Actigraph specifically designed for the non-invasive monitoring of animals in veterinary applications. Its tiny size means that it can be used to record sleep, activity and circadian rhythm on animals of all sizes.

The Nano is a collar mounted device containing a tri-axial accelerometer which records physical movement and temperature for up to 90 days which may then be wirelessly downloaded to a PC for analysis. The fully waterproof miniature case is constructed of robust aluminium alloy and tough plastic end cap providing reliable data capture in the harshest of conditions.

The Nano may also be set up for scheduled downloads which allows the data to be extracted without disturbing the animal which greatly reduces handling time and stress.

The Nano uses our MotionWare software package which includes tools for the analysis of sleep, circadian rhythm, and physical activity providing key objective endpoints for veterinary research.

The Nano is recharged using the USB-C powered NanoDock which also enables Bluetooth for set-up and download. A 6 position Nano MultiDock is also available to facilitate simultaneous charging of multiple devices.

The Nano replaces our legacy Actiwatch Mini which had been in service since 2006. The Nano has an Actiwatch Mini compatible recording mode to closely match the counts from the legacy device.

The Nano is not intended for human use (i.e. it is not a medical device) – please consider MotionWatch 8.

MotionWare Software

The MotionWare Software is a companion software suite that allows for the set-up, download and analysis of data captured with the Nano.

The Nano device manager allows the Nano to be set-up for a new recording in either long-term (Bluetooth OFF) or scheduled mode whereby Bluetooth is enabled for specific periods to allow remote download.

Available for both Windows and Mac OS*, the MotionWare software provides device management tools such as battery monitoring in addition to data management tools including flexible report generation and bulk text export.

MotionWare also provides a suite of analysis functions for Sleep, Circadian Rhythm, Physical Activity and Ambient light data.
