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.

Bi-phasic quasi-static brain communication device and method

A variable capacitor device comprises first and second control paths which are configured to enable differential control using first and second transistors of a same doping type in the first and second control paths, respectively, wherein the first and second transistors are configured as voltage variable resistors for tuning a capacitance of the variable capacitor device.
