There are more than 1.60 billion smartphone users in the world. We find ourselves looking for chargers every now and then whenever we are outside the comforts of our homes. Statistics show that people with ages ranging from 18-30 years are the ones spending most of their time with smartphones. On average, U.S. smartphone owners spend 58 minutes daily on their phones. With this much usage, there emerges a need for regular and frequent charging of these phones. In order to solve this problem, Korean researchers from Korea Advanced Institute of Science and Technology (KAIST) have come up with a wireless charging system that is capable of charging 40 smartphones simultaneously.
By using this Dipole Coil Resonant System (DCRS) technology, not only can we charge 40 smartphones simultaneously, but also portable devices such as laptops and other gadgets. Professor Chun T. Rim from KAIST hopes that wireless charging technology would become as popular as wifi technology one day. This would relieve people of worrying about taking their chargers along whenever they go outside. “Although the long-range wireless power transfer is still in an early stage of commercialization and quite costly to implement, we believe that this is the right direction for electric power to be supplied in the future,” he said. “Just like we see Wi-Fi zones everywhere today, we will eventually have many Wi-Power zones at such places as restaurants and streets that provide electric power wirelessly to electronic devices. We will use all the devices anywhere without tangled wires attached and anytime without worrying about charging their batteries.”
For now, this new technology sounds pretty exciting and will surely open new avenues.
