Decided on a project 10/12/07

New idea for senior project: wireless battery charger. Air-core transformer, device (cell phone to demonstrate) charges when in close proximity to charging device (some sort of cradle for proper positioning if necessary). Secondary coil contained within battery pack.

Considerations: Must be low power to reduce chance of interference. Need to ensure will not induce currents in device circuitry. Or, don’t worry about using in a device; just concentrate on charging wirelessly for now. Companies currently developing this concept: NTT DoCoMo (in Japan with Panasonic), SlashPower LTD (www.slashpower.com).
