Ambient Backscatter IoT

Battery-free devices powered by harvesting ambient RF energy.

Ultra-low-power communication systems where devices reflect and modulate existing wireless signals (WiFi, cellular, TV) without requiring batteries or active transmitters. Enables massive-scale deployment of disposable sensors for agriculture, cold-chain logistics, and environmental monitoring in developing regions.
