Power-saving design opportunities for wireless intracortical brain–computer interfaces | Nature Biomedical Engineering
Analyses of data from intracortical brain–computer interfaces implanted in rhesus macaques and in a human suggest that the circuit design parameters of current recording interfaces can be relaxed considerably without loss of performance.
Subjects Biomedical engineering Brain–machine interface Electrical and electronic engineering Abstract The efficacy of wireless intracortical brain–computer interfaces (iBCIs) is limited in part by the number of recording channels, which is constrained by the power budget of the implantable system. Designing wireless iBCIs that provide the high-quality recordings of today’s wired neural interfaces may lead to inadvertent over-design at the expense of power consumption and scalability. Here, we report analyses of neural signals collected from experimental iBCI measurements in rhesus macaques an
