Abstract
An integrated circuit (IC) includes a first circuit layer that includes a first wireless power transfer (WPT) device, a first chip electrically connected to the first circuit layer, and a first tracking circuit disposed in the first chip. The first WPT device may be configured to extract energy from an electromagnetic signal and provide an output voltage. The first tracking circuit may be powered by the output voltage of the first WPT device and may output tracking data in response to an instruction extracted from the electromagnetic signal.
