    • Wireless or Electromagnetic Induction is a technology in which a unit that is plugged in uses a coil to create a magnetic field, which a coil in or attached to another device can absorb the magnetic field converting it into energy to charge a battery of some sort.

    • This technology has been around since 2006, but it is an inefficient way to charge a device because the field dissipates with distance, so to make it more efficient MIT researchers used magnetic resonance to make wirelessly charging more efficient.

    • Magnetic Resonance is only efficient for about 12 feet and even at that distance only 50-70 percent of the energy actually makes it from the source of the power to the thing that is suppose to be powered.

    • Using microwave transmission the range can be up to 13 miles.

    • SHARP

    • Unmanned UAV from NASA Dryden.

    • Today the most common uses for wireless induction is in:

    • Electric Toothbrushes

    • Wireless Chargers

    • Charging Laptop Batteries (Dell Latitude Z Laptop)
