Project Description
What if a device could transmit data without a battery, a power cord, or a dedicated transmitter?
It sounds like science fiction, but it is the reality of ambient backscatter communication. Project AURA explores a world where electronics survive entirely off the grid by communicating on “borrowed” energy.
Instead of generating their own radio waves, the devices we are building piggyback on the invisible sea of Wi-Fi, TV, and cellular signals already surrounding us. Think of it like using a mirror to send Morse code using the sun: you aren’t generating the light; you are just cleverly reflecting it. By making microscopic changes to how an antenna reflects ambient RF (Radio Frequency) waves, AURA devices can encode and transmit data using virtually zero power.
You’ll dive into the world of electronics, wireless communication, and embedded systems as you design circuits, program microcontrollers, and experiment with real radio signals. Along the way, you’ll uncover how information travels invisibly through the air, how modern wireless devices communicate, and how engineers are pushing the limits of what is possible with near-zero-power technology.
