Abstract:
An RF charging system for implantable medical devices. The RF charging system includes a radio frequency (RF) signal, a first antenna configured to transmit the RF signal, a second antenna configured to receive the RF signal transmitted by the first antenna, tune characteristics of the RF signal, and improve power transfer with impedance matching circuitry, an RF to direct current (DC) converter configured to convert the RF signal of the second antenna into a DC signal, and a battery management circuit configured to receive the DC signal and provide voltage to a battery.
