Abstract: A system and method for brain-machine interface communication utilizing Bi-Phasic Quasi-Static Brain Communication (BP-QBC). The system includes a first device and a second device that are in wireless communication together. The system and method include signal transmission between the first device and the second device through dipole coupling. The system is configured to utilize compressive sensing and collision avoidance for enhanced net energy efficiency. The system and method utilize fully electrical quasi-static signaling to militate against energy transduction losses.
