Wireless Power Technology Developed by German Researchers
Everyone has experienced the frustration of tangled cords and cables. Not only are they unsightly, but they can also be dangerous tripping hazards. Researchers at the Fraunhofer Institute for Electronic Nanosystems (ENAS) in Paderborn, Germany, have collaborated with researchers from the University of Paderborn and four mid-sized technology companies to develop a new technology that can power electronic devices without cables. “Without cables, lamps can be placed anywhere on the table and look more aesthetically pleasing,” says Dr. Christian Hedayat, department head at ENAS in Paderborn.
The researchers have answered the question of how to power electronic devices without cables and batteries with a principle that is similar to an induction stove. A network of coils is installed in the table, each representing a transmitting antenna. When electricity flows through the coils, they generate a magnetic field. The magnetic field then causes electricity to flow in a coil that is located in the base of the lamp. The lamp is not only powered in a specific location on the table, but across the entire surface. The researchers have solved the problem of radiation exposure by making only the coil active under the lamp.
The technology is still in the development phase, but the researchers plan to bring lamps with the new technology to market first. The circuit boards will be available in various sizes so that customers can retrofit both small and large tables. The new wireless power technology can also power a variety of other technical devices, and it can even send data through the table. In the medical field, the technology can be used to power implants, such as pressure sensors in the brains of stroke patients that alert doctors when the pressure becomes too high.
In conclusion, the new wireless power technology developed by German researchers has the potential to revolutionize the way we power electronic devices. It eliminates the need for cords and batteries, making devices more aesthetically pleasing and safer to use. The technology is still in the development phase, but it has practical applications in a variety of fields, including medicine.
