POWER WITH NO STRINGS ATTACHED

摘要

Any technology that offers to free applications from power cords and wall warts will confer a definite salable edge on electronic devices. Applications that would benefit from wireless power range from portable consumer electronics, such as cell phones and MP3 players, which could jettison their wall warts and power adapters, to low-power wireless-sensor networks, which could be free of frequent bat-rntery replacement, to medical implants in patients who could avoidrnsurgery to replace batteries.
