Patent attributes
Numerous aspects of communication devices, methods, and systems are described in this application. One aspect is a system comprising a body having a skin facing surface and an opposing surface and an energy generator operably coupled to the body and comprising a plurality of generator elements operable to output a plurality of different energy types in a signal direction toward skin. Each generator element of the plurality of generator elements may be independently operable to output one energy type of the plurality of different energy types in the signal direction. When the skin facing surface of the body is positioned relative to the skin, the energy generator may affect tissues associated with or adjacent to the skin by causing one or more generator elements of the plurality of generator elements to output an energy signal in the signal direction with one or more different energy types.
