Modern methods of wireless charging of electronic devices of technology work only if the general parameters of the system are configured for a certain transmission distance.
This has some limitations: for effective charging, the device needs to be constantly at a certain distance from the energy source.
The natural frequency of the system is the frequency at which the system works well and which contributes to the efficient transfer of energy to the device. In a system developed by researchers, this oscillation frequency independently adapts to changing conditions, which can be the movement of a device receiving energy on a scale of less than a millisecond. Thus, the system supports efficient transmission, even when the device is in fast motion.
In addition, the system allows you to charge the device almost regardless of how far it is from the power source. During testing, she was able to stably transmit 10 W power to a battery that was at a distance of 0 to 65 cm and moved at a constant speed.
Previously, scientists created a butane ceramic battery. The new technology will expand the range of applications for ceramic fuel cells for portable and mobile devices such as electric cars, robots and drones.
