1. A device, comprising:
a first non-conductive layer, a second non-conductive layer on the first non-conductive layer, a third non-conductive layer on the second non-conductive layer, a fourth non-conductive layer on the third non-conductive layer, and a fifth non-conductive layer on the fourth non-conductive layer;
a loop antenna within the third non-conductive layer and on the second non-conductive layer, the loop antenna including one or more surfaces that are exposed from the third non-conductive layer and covered by the fourth non-conductive layer;
an integrated circuit device in the fifth non-conductive layer including a first and a second contact;
one or more spaces extending through the third and fourth non-conductive layers spaced apart from the integrated circuit device;
a first and a second electrode each in one of the one or more spaces and coupled to the loop antenna;
a first conductive layer coupled to the first contact including a first end in one of the one or more spaces, the first end overlapping the first electrode; and
a second conductive layer coupled to the second contact including a second end in one of the one or more spaces, the second end overlapping the second electrode,
wherein the first end, the second end, the first electrode, and the second electrode include:
a resting state in which the first end and the second end are electrically isolated from the first electrode and the second electrode, respectively; and
an actuated state in which the first end and the second end are in electrical communication with the first electrode and the second electrode, respectively.
