Example: Dry Electrode Design
Electrodes facilitate the electro-chemical connection of the skin to the Analogue Front End (AFE).
Typical hospital electrodes use a hydrogel on a silver/silver-chloride material to maximise the signal transfer but this cannot be always practical in regular consumer devices.
Examples of suitable dry electrodes include copper, stainless steel and conductive rubber. Further technical guidance can be provided under NDA.
The Lead 1 setups require at least one lead i.e. two electrodes to connect with the user across the heart. For lead 1 configurations, a third “right leg drive” electrode can be utilised to reduce noise on the signal.
