1. A wearable device, comprising:
a housing, wherein the housing includes a contact surface for contacting an external body surface;
a physiological sensor mounted on a first side of a flexible circuit board disposed within the housing;
electronics disposed within the housing, wherein the electronics comprise a controller that is configured to operate the physiological sensor to detect one or more physiological parameters via the external body surface;
a coil configured to receive electromagnetic energy for powering the electronics, wherein the coil is disposed within the housing proximate to the contact surface of the housing, wherein the coil comprises a plurality of windings that surround the physiological sensor;
a magnetic shield disposed within the housing between the coil and at least one electronic component of the electronics, wherein the magnetic shield shields the at least one electronic component from electromagnetic energy, wherein a second side of the flexible circuit board, which is opposite the first side of the flexible circuit board upon which the physiological sensor is disposed, along with the coil are both mounted on the magnetic shield, wherein the flexible circuit board passes through a slot in the magnetic shield to provide an electrical connection between the electronics and the physiological sensor, and wherein the physiological sensor and the coil are both mounted on a common side of the magnetic shield while the controller that is configured to operate the physiological sensor is disposed on an opposite side of the magnetic shield; and
a battery disposed within the housing and positioned between the electronics and the magnetic shield.
