Composite integrated circuits and methods for wireless interactions therewith
A composite integrated circuit (IC) includes a first circuit layer, a second circuit layer having a first chip and a second chip, and a first wireless power transfer (WPT) device in the first chip or the first circuit layer. The first WPT device generates a power supply voltage by extracting energy from an electromagnetic signal. A first tracking circuit in the second chip or the first circuit layer is powered by the power supply voltage from the first WPT device and stores or outputs tracking data in response to an instruction extracted from the electromagnetic signal.
