Researchers at the Korean Advanced Institute of Science and Technology (KAIST) have developed an omnidirectional wireless charging technology that is capable of charging multiple devices at once. Amazingly, the technology can charge devices from a distance and at peak efficiency regardless of the devices' physical orientation.
Wireless charging, also known as inductive charging, is becoming increasingly popular even though the technology is still new and comes with certain restrictions and glitches.
However, the KAIST researchers' work appears to suggest that this omnidirectional wireless charging technology is capable of powering either 30 smartphones or up to five laptops simultaneously. Importantly, the device does so safely and meets safety levels set by the International Commission on Non-Ionizing Radiation Protection.
