Activ8 Wearable Activity Tracker GEN2


2nd generation Activity tracker – Perfected for professionals

Activ8 second generation wearable activity tracker is the ultimate physical activity tracker for lifestyle, research, studies and education. With Activ8 Gen 2, you can seamlessly monitor and record physical activity data with ease and precision. With all the insights gained over the previous years, this activity tracker has been enhanced to become the ideal solution for professional applications.

Recordings Upto 5 Weeks

Our advanced technology allows Activ8 2nd generation to capture and store up to 6 weeks of physical activity data using an 8 Mbyte internal memory.

An extended memory variant will be available soon for research purposes, featuring a 256 MByte capacity specifically designed for capturing and storing raw data over extended durations.


The Activ8 2nd generation activity tracker utilizes a rechargeable battery with a capacity of 140mAhr, which is 50% larger than the battery in the previous Activ8 model.

Charging can be conveniently performed through the micro-USB connector using a USB charger or the Activ8 docking station, capable of accommodating up to 5 trackers simultaneously.

Direct & Easy Access

Accessing your measurement data has never been easier. Simply download your recordings from the Activ8 activity tracker and retrieve comprehensive data insights from the convenience of your local computer using the supplied Activ8 software application.

No Cloud. Simple & Secure.

After downloading a recording from your Activ8 activity tracker to your local computer the measurement data (csv format) is directly accessible for further processing in third party tools. Rest assured, your data remains confidential as we prioritize your privacy by eliminating cloud storage.

IP67 Waterproof

With its impressive IP67 waterproof rating, this tracker is built to endure even the harshest conditions, ensuring reliable performance and durability.

Activity tracker with automatic activity recognition

Best in class automatic activity recognition

Activ8 offers a groundbreaking feature – the ability to automatically classify the user’s daily activities, providing a detailed minute-by-minute overview of their every move. This unprecedented insight into a person’s daily life reveals precisely when and how long they were sitting, standing, walking, cycling, or running, without the need for manual confirmation. The classification process is fully automated, delivering accurate results effortlessly.

Accurate step counting

Experience precise step counting with Activ8, a step counter validated by Erasmus Medical Center. Whether you have a steady and firm gait pattern or a more fragile one, Activ8 ensures accurate step tracking for all users. Obtain crystal-clear insights into the fitness and mobility of elderly individuals and other user groups through this valuable information.

Use as Sleep tracker

Transform the Activ8 activity tracker into a versatile sleep tracker by placing it on the chest. Gain valuable insights into a user’s movements throughout the night, capturing data on positions such as lying on the back (supine), on the belly (prone), or on the sides. This invaluable information offers deep analysis of sleeping patterns and behaviors.

Additionally, 2M offers full contactless bedsensor solutions, enabling seamless tracking without direct physical contact. For further details, reach out to 2M using the provided contact form.

Customizable user interface

The Activ8 activity tracker features a user-friendly button and five programmable RGB light indicators that provide real-time information on wireless connectivity status, battery level, and the user’s activity results in all possible color combinations. Furthermore, the device can be equipped to deliver vibro-tactile feedback, ensuring effective alerts and notifications.

For OEM projects, the user interface can be completely tailored to meet your specific requirements.

Activ8 Patch

Pocket. Legstrap. Patch. Watch

For automatic activity recognition, the Activ8 tracker has to be worn on the upper leg. There are various options for doing so. The least intrusive method involves placing the activity tracker in a pocket, although for the highest accuracy, we highly recommend using a leg strap or Activ8 patch.

The advantage of using a patch lies in its consistent placement throughout the entire measurement period, eliminating the need for users to think about it constantly. Moreover, the patch allows for prolonged measurements without any additional precautions during showering, ensuring a hassle-free experience.


Activ8 is CE certified for non-medical use. Should you require it, we offer the option to obtain Medical Device certification or certification for countries beyond Europe upon request.
