Activ8 Adhesive 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.
