1. A wearable auricular stimulator, comprising:
a first flexible body portion adapted to be worn at least partially around an auricle of a wearer, the first flexible body portion comprising
a skin-facing external side, and
an internal side opposite the skin-facing external side, the internal side comprising at least one protrusion for supporting a three-dimensional circuitry layout, the at least one protrusion protruding away from the skin-facing external side;
three-dimensional circuitry on the internal side of the first flexible body portion, wherein the three-dimensional circuitry comprises
a plurality of conductive traces deposited at least in part on the first flexible body portion, such that at least a portion of the plurality of conductive traces is configured to stretch and/or flex with movement of the first flexible body portion, and
a plurality of electrodes configured to deliver electrical stimulation therapy to the wearer via the skin-facing external side of the first flexible body portion;
a plurality of electronic components coupled to the three-dimensional circuitry, wherein
each electronic component of the plurality of electronic components is electrically coupled with one or more corresponding traces of the plurality of conductive traces and/or one or more corresponding electrodes of the plurality of electrodes of the three-dimensional circuitry,
the plurality of electronic components comprises two or more elements of different types selected from the group of element types consisting of an illumination element, a processing circuitry element, a physical control element, a communications element, a memory element, and combinations thereof, and
each electronic component of one or more electronic components of the plurality of electronic components is disposed on or above one or more respective protrusions of the at least one protrusion; and
a second flexible body portion configured to mate with the first flexible body portion, thereby substantially encapsulating the three-dimensional circuitry and the plurality of electronic components.
