Abstract
The invention provides devices and methods for using acoustics to communicate between a macro-scale transceiver and a micro-device or between multiple micro-devices. The micro-devices may passively scatter sound from a transceiver or actively generate sound. Acoustic waves can also provide power to a micro-device.
