The everbeat Watch Key Components
Figure 2: Back of the everbeat watch
1. Battery Charger Leads – The two gold colored pickups on the far left of the bottom of the
everbeat watch line up with corresponding pickups on the charging station.
2. PPG sensor - The green light is a photoplethysmogram, or PPG, sensor. It has been
disabled and will not be used by the everbeat system at this time.
3. ECG Contacts – These ECG contacts on the bottom of the watch touch your wrist and
create a circuit through your body when you touch the ECG sensor on the top of the watch
face. Imagine a circuit starting from these two pickups, traveling up your arm, through
your chest and down your other arm, and ending at your finger pressing on the ECG sensor
on top of the watch. This is how everbeat records your ECG.
4 Wrist Band – The wristband secures the watch to your wrist. It includes a button (#4), a
loop (#5), and 10 adjustment holes (#6).
7 Watch band screws – used to secure the band to the watch body. Not to be serviced by
the user.
