Claim	A wireless device, comprising: a near-field transceiver configured to be coupled to a host structure; a controller coupled to the transceiver; wherein the near-field transceiver includes a feed point configured to be coupled to a conductive surface; wherein the conductive surface is configured to be capacitively coupled to the host structure to form part of a near-field electric antenna; and wherein the conductive surface is configured to be in repeated, but not continuous, contact with a ground. The device of claim 1 : wherein the conductive surface is configured to be in repeated contact with the ground in response to the host structure walking, running prancing, rotating, grasping, touching, and/or stopping then standing. The device of claim 1 : wherein the ground is at least one of: earth ground, an assembly line, soil, a road, a trail, or a floor. The device of claim 1 : wherein the conductive surface is a horseshoe. The device of claim 1 : wherein the conductive surface is at least one of: a metal safety shoe, a robotic contact foot, a grasping device, and/or part of a vehicle's track structure. The device of claim 1 : wherein the feed point is coupled to the conductive surface with a conductive via. The device of claim 6 : wherein the conductive surface is a horseshoe; and wherein the conductive via is at least one of: a nail, a spike, a bolt, or a clamp. The device of claim 1 : wherein the host structure is a horse. The device of claim 1 : wherein the host structure is at least one of: a person, a robot, livestock, an assembly line machine, or a vehicle track. The device of claim 1 : wherein the wireless device is configured to communicate with another wireless device when the conductive surface is not in contact with the ground. The device of claim 1 : wherein the wireless device is configured to enter a low-power state when the conductive surface of the wireless device is in contact with the ground. The device of claim 1 : wherein the host structure is a horse; wherein the conductive surface is a horseshoe; wherein the horseshoe is coupled to a hoof of the horse; wherein the ground is earth; wherein the wireless device is configured to communicate with another wireless device when the hoof is not touching the earth; and wherein the wireless device is configured to not communicate with another wireless device when the hoof is touching the earth. The device of claim 1 : wherein the wireless device is a first wireless device; further comprising a second wireless device configured to be coupled to the host structure and having a near-field transceiver and a far-field transceiver; wherein the second wireless device is configured to receive a near-field electric signal from the near-field electric antenna of the first wireless device. The device of claim 13 : wherein the second wireless device is spatially further from the ground than the first wireless device. The device of claim 1 : further comprising an intermediate structure configured to be coupled between the conductive surface and the host structure; and wherein the near-field transceiver and the controller are physically coupled to the intermediate structure. The device of claim 15 : wherein the intermediate structure is a disposable pad. The device of claim 16 : wherein the intermediate structure is a dielectric structure. The device of claim 1 : further comprising a sensor coupled to the controller; wherein the sensor is configured to detect when the conductive surface is in contact with the ground. The device of claim 18 : wherein the sensor is configured to measure a physiological parameter of the host structure. The device of claim 18 : wherein the sensor is at least one of: an accelerometer, an infra-red proximity sensor, a pressure sensor, or a pressure plate. The device of claim 1 : further comprising a near-field magnetic antenna including a coil; wherein the coil is coupled to the near-field transceiver; and wherein together the coil and conductive surface function as a near-field electromagnetic induction (NFEMI) antenna. A method of making a wireless device, comprising: selecting an intermediate structure, a horseshoe, and a nail or screw; wherein the intermediate structure includes a near-field transceiver coupled to a controller; coupling the near-field transceiver to the horseshoe with the nail or screw; wherein, upon coupling, the horseshoe is capacitively coupled to the horse to form a near-field electric antenna.
