Research team Modern home filled with all kinds of wires, Socket Not only unsightly, but also cause some Security Hidden. British "Daily Mail" on the 8th of "cordless Bulb "The story, to let people see the hope out of the trouble. Cordless light bulb from the Massachusetts Institute of Technology researchers have developed. Scientists hope to expand this technology to other areas, ultimately Mobile , Notebook Wireless devices such as automatic charging. Principles of the use of electric magnetic resonance The idea of wireless power transmission has long been proposed, but was unable to achieve many scientists believe. Because Launch Emitted electromagnetic energy scattered around the transmission, humans can not be centralized control of the electromagnetic energy, a fortiori, be used. But last fall, Massachusetts Institute of Technology physics professor Marin? has proposed a can, "the radio can transmit" technology using a new theory of electromagnetic energy. In accordance with theory, as long as electromagnetic energy transmitter with receiving equipment at the same resonance frequency, the energy between them can be interchangeable. "It's like theater star can be Glass Shattered, like, " said," on condition that the two singers and glass to form a resonant acoustic. " 60-watt lamp lit experiment The basis of this theory, 6 team led by experiment. They used two copper coils act as a resonator. A coil with Power supply Connected to a transmitter; Another Table lamp Connected to act as a receiver. Result, they succeeded in a 2.13 meters away from the transmitter 60 watt lamp lit. Most important, the study showed "the radio can transmit" technology to humans. Because the electromagnetic field can only resonate with the items affected, such as human, tables, Blankets And other items almost no response to the electromagnetic field. Prospects goodbye socket For "radio can transmit" technology's success, "Daily Mail" comments, "This may declare the end of the socket coming." "As long as the room where the laptop can be equipped with radio transmitter, it can no longer connected to the computer and the outlet to charge, because it will automatically charge." Team member Peter? Professor Fisher said. in an interview, also said modern Life In full of wires, outlets of the world, and wireless power transmission technology will be possible for the human part out of wire, Battery Annoyance. So, this is a promising new technologies. Next, the team needs to be done is to increase the transmitter power and receiver to receive efficiency. By then, mobile phones, laptop computers can be equipped with the transmitter in the room is charged automatically, even without the battery, do not need to connect through the socket and power supply can be used directly. Too much energy loss limits Although "Radio can transfer" technology have seen the emergence of people out of wire, charging the hope of trouble, but the research team recognized that "the radio can transmit" technology should be improved, to enter people's home. In led lamp experiments, the energy of electromagnetic energy transmitter is only 40% to 50% absorbed by lamp, if it is to right Chemical batteries Wireless charging, the battery receiving rate must be increased to 70% or more. To light a 60 watt light, the researchers use transmitters must configure a diameter of about 0.6 meters of copper wire coil. If the rooms in order to realize the whole Electrical Can automatically charge, copper wire coil is expected to reach 2.1 meters in diameter.
