I am working at Neuspera Medical on neural stimulation implants that are wirelessly powered by a small RF Transmitter, worn on the outsize of the body. The system is controlled via an iPad. The surgical procedure can be done in a doctor's office.
My focus is on the RF transmitter, which is powered by a Li-ion battery. RF is transmitted into the body by a quad-antenna phased array. We have multiple Keysignt test equipment in the lab. Not pictured is a VNA that's on a metro cart; it's out for calibration, so no pictures of it.
