It’s not necessary. When you have completed or early termed a Subject in the Research Portal, the Embrace device will automatically be disassociated from the Subject.
A Subject can participate in multiple studies (i.e., pre-clinical, clinical, post-clinical) and have the same assigned Subject ID throughout the studies. However, use of the same Embrace device is not necessary. Once the Embrace has been unpaired and disinfected, you can start using it for another Subject.
