Researchers at the Massachusetts Institute of Technology in the United States recently announced that they have illuminated a 60-watt light bulb at a distance of 2 meters by wirelessly transmitting power. Scientists believe that this technology is expected to be able to charge mobile phones and other portable appliances without the need for power cords in the future. Relevant research articles were published on the website of Science in the United States recently.
Marin Solgasic, a professor of physics at MIT, discovered that energy can be transmitted wirelessly using specially tuned waves. The principle is to make the charging device and portable small appliances vibrate at the same frequency. The researchers applied this principle to conduct experiments with success, and the experiments could be repeated.
Professor Solgasic believes that there is no urgent need for wireless transmission of power at present, but it is foreseeable that if this technology can be put into practical application, at least many electrical devices will no longer need batteries, and batteries It is another major culprit of polluting the environment.
However, this technology needs further improvement before entering practical applications. First of all, the energy efficiency of the test system is only 40-45, which means that more than half of the energy is wasted in the transmission project. Scientists believe the technology would need to be twice as energy efficient as existing transmission methods. Secondly, the geometric size of the copper coil that transmits electrical energy is too large, 60 cm wide, and must be reduced in size for practical applications. Third, the transmission distance of 2 meters needs to be further increased. The goal is to use one charging device to provide power for multiple portable appliances in the same house.
The researchers also stated that the electromagnetic coupling method used in this technology is harmless to humans and animals.
