Relay module for implant
First Claim
1. A system, comprising:
- a control module comprising a first antenna, the control module being configured to generate a first radio frequency (RF) signal and transmit the first RF signal using the first antenna; and
a wirelessly powered relay module configured in a layered structure and comprises;
a receiver antenna layer configured to receive the first RF signal transmitted by the first antenna of the control module;
at least one dielectric insulating layer; and
a transmitter antenna layer arranged to be separated from the receiver antenna layer by the dielectric insulating layer, wherein the transmitter antenna layer is configured to transmit the second RF signal, wherein the second RF signal is generated during a stimulation portion of the first RF signal, wherein the second RF signal is amplified solely based on a charge stored during an initial portion of the first RF signal, and wherein the initial portion precedes the stimulation portion, and wherein the second RF signal encodes a stimulus waveform.

Abstract
An implementation provides a system that includes: a control module including a first antenna, the control module configured to generate a first radio frequency (RF) signal and transmit the first RF signal using the first antenna; an implantable lead module including a second antenna and at least one electrode configured to stimulate excitable tissue of a subject; and a relay module configured to receive the first RF signal; generate a second RF signal based on the first RF signal, the second RF signal encoding a stimulus waveform to be applied by the at least one electrodes of the implantable lead module to stimulate the excitable tissue of the subject; and transmit the second RF signal to the implantable lead module.
