摘要

If the father of electromagnetism, Michael Faraday, could be transported into the 21st century, he would no doubt be awestruck by the iPhone. After five hours of tapping its touch screen to browse the internet, make calls, play games and determine his location via satellite-positioning, he might also find himself a little puzzle d. Why, with all the advances in technology and communications, would such a sophisticated device still need to be plugged in to be recharged? If phone calls and web pages can be beamed through the air to portable devices, then why not electrical power, too? It is a question many consumers and device manufacturers have been asking themselves for some time-and one that both new and established technology companies are now hoping to answer.rnTo seasoned observers of the electronics industry, the promise of wireless recharging sounds depressingly familiar. In 2004 Splashpower, a British technology firm, was citing "very strong" interest from consumer-electronics firms for its wireless charging pad. Based on the principle of electromagnetic induction that Faraday had discovered in the 19th century, the company's "Splashpad" contained a coil that generated a magnetic field when a current flowed through it. When a mobile device containing a corresponding coil was brought near the pad, the process was reversed as the magnetic field generated a current in the second coil, charging the device's battery without the use of wires. Unfortunately, although Faraday's principles of electromagnetic induction have stood the test of time, Splashpower has not-it was declared bankrupt last year without having launched a single product.
