Provided is a wearable, self-contained drug infusion or medical device capable of communicating with a host controller or other external devices via a personal area network (PAN). The medical device utilizes a PAN transceiver for communication with other devices in contact with a user's body, such as a physiological sensor or host controller, by propagating a current across the user's body via capacitive coupling. The wearable nature of the medical device and the low power requirements of the PAN communication system enable the medical device to utilize alternative energy harvesting techniques for powering the device. The medical device preferably utilizes thermal, kinetic and other energy harvesting techniques for capturing energy from the user and the environment during normal use of the medical device. A system power distribution unit is provided for managing the harvested energy and selectively supplying power to the medical device during system operation.

The disclosed technology relates to a method for receiving a near-field radio wave, the wave being received using electromagnetic-wave conduction capacities of the body of a user who is able to make a validation gesture that modifies characteristics of the radio wave. The method includes detecting a first modification of a characteristic of the radio wave, the first modification being resultant from a start of the gesture, and detecting a second modification of a characteristic of the radio wave, the second modification being resultant from an end of the gesture, where the acquisition of a right for the user is dependent on the first modification and the second modification.
