Abstract
Devices and methods are described for transmitting acoustic waves through a fluid medium to communicate between a macro-scale transceiver and micro-devices or to communicate between micro-devices. Acoustical transmission can be used to communicate data or to provide power to the micro-device(s). The ability to transmit and receive on multiple frequencies can optimize the transmission for a particular situation.
