Abstract: A wearable vital sign monitor. The wearable vital sign monitor includes a band, where the band secures the wearable vital sign monitor relative to a user. The band includes an interior surface, the interior surface being the surface closest to the skin of the user and an exterior surface, the exterior surface opposite the interior surface. The wearable vital sign monitor also includes a first sensor array. The first sensor array is attached to the band and includes at least two sensors. The wearable vital sign monitor further includes a second sensor array. The second sensor array is attached to the band a fixed distance from the first sensor array and includes at least two sensors. The wearable vital sign monitor additionally includes an electronics module. The electronics module is configured to receive a first signal from the first sensor array, receive a second signal from the second sensor array, and transmit the sensor data to an external device.
