Features

Programmable Display

The ActiGraph Link features a programmable LCD window that can be configured to display date and time and/or provide real-time activity feedback such as steps and kcals, or it can be completely disabled.

Inertial Measurement Unit (IMU)

An integrated IMU containing a gyroscope, magnetometer, and secondary 3-axis accelerometer sensors provides raw position and rotational data for a variety of advanced applications, including inclination, gait analysis, and fall detection.*

Bluetooth® Smart

The ActiGraph Link is powered by Bluetooth® Smart technology and offers a variety of wireless features, including heart rate monitoring, proximity detection, and communication with ActiGraph’s suite of mobile applications for iOs and Android devices.

Wear Time Sensor

An advanced wear time sensor on the back of the device uses capacitive touch technology to automatically detect when a wrist worn device has been removed for simplified compliance monitoring and data cleaning.
