NuCurrent was founded out of a graduate-student project at Northwestern University that focused on powering implanted neurostimulation devices wirelessly. From 2009-2013, NuCurrent focused exclusively on wireless power for implanted medical devices. We were challenged to develop a new type of antenna technology to deal with complex issues like transmitting power through inconsistent human tissue, Specific Absorption Rate (SAR) limits, tissue heating, implant variability, and significant size restrictions.
