Sensing and charging of electronic devices using coils. A software-defined collaborative sensing approach can allow detection and location of multiple electronic devices with respect to a charging surface to allow for wireless charging thereof. Systems and methods can measure the interaction of devices with a generated magnetic field through a network of nested sensing coils that can sense the location of devices located around the network of coils based on their interaction with magnetic fields. Once the location of a device to be charged is determined, charging energy can be directed to the device based on its location on the charging surface. The charging surface can include one or more sensing nodes having a combination of nested active, or driven, and passive coils. These coils can be configured to transform existing two-dimensional (2D) surfaces or three-dimensional (3D) areas into a multi -device contactless wireless charger.

A navigational constraint model may prescribe a navigation path along which a wireless power transmission system can provide wireless power to the mobile device. Deviations from the prescribed path may require the mobile device to self-power. The prescription of a navigation path allows for the use of reduced-complexity wireless power transmitters that are fully capable of servicing the prescribed path. Multiple embodiments of prescribed paths with various limitations and features are set forth herein, along with multiple embodiments of wireless power transmission systems of reduced complexity and functionality to fully service the various embodiments of prescribed paths.

System and methods are described herein for providing wireless power to a target device, such as a laptop computer, a mobile phone, a vehicle, robot, or an unmanned aerial vehicle or system (UAV) or (UAS). A tunable multi-element transmitter may transmit electromagnetic radiation (EMR) to the target device using any of a wide variety of frequency bands. A location determination subsystem and/or range determination subsystem may determine a relative location, orientation, and/or rotation of the target device. For a target device within a distance range for which a smallest achievable waist of the Gaussian beam of the EMR at an operational frequency is smaller than the multi-element EMR receiver of the target device, a non-Gaussian beamform may be determined to increase efficiency, decrease overheating, reduce spillover, increase total power output of rectenna receivers on the target device, or achieve another target power delivery goal.
