1. A method to collect physiological data using a dynamically configurable biopotential electrode array, comprising: detecting contact between at least two contiguous electrode tiles of the biopotential electrode array and skin of a user; electrically coupling the at least two contiguous electrode tiles, based on detecting contact, to form a first active electrode area within the biopotential electrode array, the first active electrode area functioning as a single electrode; and collecting physiological data associated with the user via the coupled electrode tiles of the first active electrode area; and, wherein the contiguous electrode tiles share a border.
