Abstract
The present invention is a wireless power system which includes components which can be recharged by harvesting wireless power, wireless power transmitters for transmitting the power, and devices which are powered from the components. Features such as temperature monitoring, tiered network protocols including both data and power communication, and power management strategies related to both charging and non-charging operations, are used to improve performance of the wireless network. Rechargeable batteries which are configured to be recharged using wireless power have unique components specifically tailored for recharging operations rather than for providing power to a device. A wireless power supply for powering implanted devices benefits from an external patient controller which contains features for adjusting both power transmission and harvesting provided by other components of the wireless power network.
