Abstract
Implantable devices and/or sensors can be wirelessly powered by controlling and propagating electromagnetic waves in a patient's tissue. Such implantable devices/sensors can be implanted at target locations in a patient, to stimulate areas such as the heart, brain, spinal cord, or muscle tissue, and/or to sense biological, physiological, chemical attributes of the blood, tissue, and other patient parameters. In some embodiments, the implantable devices can include power management schemes that have one or more AC-DC conversion chains arranged and configured to rectify the induced alternating current or voltage into one or more energy domains. Methods of use are also described.
