Wireless Energy Transfer
- Wireless energy transfer relies on the principle of interference, where synchronized waves amplify energy in one direction.
- Multiple synchronized energy sources can direct energy to specific points, similar to a magnifying glass.
Timing Control
- Timing control allows for dynamic direction changes in energy transmission without physical movement.
- This enables the creation of focal points where energy is concentrated, like a magnifying glass.
Wireless Energy Demo
- Hajimiri's team built electronic chips and antennas that transmit energy wirelessly.
- A demonstration showed a generator powering light bulbs and a drone, showcasing the technology's potential.
