Abstract

A wearable device comprising a first array of non-optical sensing nodes is disclosed. The first array comprises a plurality of nodes. The plurality of nodes are operable to sense vasodilation of an artery in proximity to the first array. Systems and methods for determining a difference between a first position and a first reference position of the first array relative to a first artery are disclosed. First signal information may be received from the wearable device. The first signal information may represent first signal variation data sensed by each node of the first array. A first position of the first array relative to a first artery may be determined based on a first signal variation pattern in the first signal information. A difference between the first position and a first reference position of the first array relative to the first artery may then be determined.
