    Two types.

    One type is a blood pressure cuff which also detects pulse.

    The other sends light through the ear lobe. As blood is pumped through the ear lobe with each beat of the heart, the amount of light which can pass through diminishes. So more light, less light, more light, less light, etc.

    Arm pressure cuff...
