摘要：
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.
