US Patent 11864914 Communication devices, methods, and systems

Exemplary aspects of an energy transceiver system are described, such as a wearable body and an energy generator comprising a plurality of generator elements operable to output a plurality of different energy types in a signal direction toward a user when the wearable body is worn. 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. A biocompatible adhesive may attach the wearable body to the skin. A controller may cause the plurality of energy generator elements to output an energy signal in the signal direction with one or more energy types of the different energy types. The adhesive may maintain a position of the wearable body relative to the user and an orientation of the signal direction relative to the living tissues(s). Related apparatus, methods, and systems are described.
