The technological impact and prospects of wireless chargers

Wireless charging technology is being applied to humanoid robots to enhance their energy autonomy. In 2026, Figure AI introduced a foot-inductive wireless charging solution for its Figure 03 humanoid robot, enabling the robot to automatically return to its charging dock for a 2-kilowatt charge. This aims to eliminate the inconvenience of wired power and manual charging, achieving longer operating times.

Robotics platform engineer Anthony En commented, "This is a significant advancement in robotics, moving beyond mere demonstrations and towards systematization. Home robots will only achieve large-scale adoption when energy management is integrated into robot autonomy."

New electronic products, especially portable devices like digital cameras, mobile phones, and tablets, are increasingly used in people's work and daily lives, and their chargers still rely on traditional wired chargers. However, wired chargers have poor compatibility and versatility, making them inconvenient for users to carry and charge. Furthermore, their disposal increases environmental pollution. Therefore, providing users with more reliable, convenient, and timely charging devices is urgently needed. The development of wireless technology has made the transmission of radio power possible, and the research and development of wireless chargers will meet user demands.

Future battery charging will take three main forms: visible charging, smart charging, and wireless charging. In 2016, the Wireless Power Consortium (WPC) had only 138 members, but this year the number of WPC technology companies has exceeded 200, including many major mobile phone manufacturers such as Apple, Samsung, HTC, Huawei, Lenovo, Xiaomi, Nokia, and Sony. Generally, a Qi wireless charger has a flat surface, called a charging pad, on which mobile devices can be placed to charge.
