Nowadays, we have wireless charging technology that is far more efficient than ever before. But it still relies on some wires and a locking plate to keep the unit tight. The charging system will work. Which is not different from using a charging cable It only helps extend the life of the charging compartment in the Smartphone longer.
Wireless charging technology is now being developed that allows us to not rely on padlocks. Can walk anywhere in the house, can be charged Just have a magnetic wave device similar to the lock plate. but can be transmitted over a longer distance Now, engineers from Aalto University have succeeded in developing a more efficient wireless power delivery device over longer distances.
They developed two loop antenna coils, each 7.2 cm (2.8 in) wide, with optimized transmission currents in the antenna. As a result, it has up to 80 percent long-range power delivery efficiency, even when placed more than 18 cm away from the charger. This is a progressive achievement.
Many people may think that only 18 cm. It’s not that far away. But this is a more advanced achievement of a real wireless charging system, because if it is the original charging pad that is locked. Just put it away without being close to each other. It’s not charging anymore. and of course in the future It will definitely go further than this…
