System for coupling acoustics waves in small devices
View Patent ↗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.
1. A system comprising:
a) a computing means programmed with acoustic field algorithms for use with frequencies above 1 MHz;
b) a data storage means for storing parameters pertaining to available or safe transmission power, micro-device acoustic coupling efficiency, and environmental attenuation;
wherein at least one optimal frequency to use for coupling acoustic waves to at least one micro-device in a given environment is computed and used to couple said acoustic waves between a macro-scale device or another micro-device and said at least one micro-device, wherein said at least one micro-device is between 10 nanometers and 200 microns in size in its smallest dimension.
2. The system of claim 1 wherein said computing means is an application-specific integrated circuit.
