Abstract
Base units, systems and methods for wireless energy transfer are described. A wireless energy transfer system according to some examples includes a transmitter of wireless energy located within a communication device, such as a mobile phone, or attached to the communication device and a distance separated receiver located within an electronic wearable device other than the communication device, wherein the receiver is configured to receive wireless energy from the transmitter and convert the wireless energy into electrical power, which may be used to power the electronic wearable device.
