Wireless Charging Market Trends

Growth Drivers

• Growing use in healthcare and medical devices: There is an extensive use of wireless charging technology in healthcare devices to revolutionize medical care, as its connector-free method creates safer medical conditions suitable for sterilization needs. The rise in healthcare technology is driving companies to design medical devices that have better efficiency and patient-friendly interfaces with simplified maintenance requirements. In May 2023, Resonant Link unveiled a wireless charging solution for implantable medical devices, including titanium-can implants. This technology delivers three times faster wireless charging at 2.5 W, allowing patients to recharge their implants in just 15 minutes while maintaining mobility during the process. These technological breakthroughs provide solutions to patient concerns about slow and overloaded charging methods, enhancing the product usage experience.

• Integration into public and commercial infrastructure: The integration of wireless charging into public and commercial infrastructure is resulting in fast-paced progress that delivers enhanced convenience while accelerating the adoption of wireless technology. Companies and city planners are implementing state-of-the-art charging systems to improve city infrastructure and user mobility accessibility. In November 2023, Detroit, Michigan, inaugurated the first public wireless charging roadway in the U.S. The project utilizes inductive coupling technology, embedding copper coils beneath the pavement to wirelessly charge EVs equipped with compatible receivers as they drive over the road. This initiative moves the field forward in merging dynamic charging systems within city infrastructure, to allow continuous charging while reducing the need for static charging hubs and improving sustainable transportation.

Challenges

• Limited range and alignment sensitivity: The high sensitivity and restricted range of the wireless charging are hindering the market growth. The device must have specific placement over the charging pad, while its alignment should match the inductive coils for efficient energy transfer. The charging performance is reduced dramatically when positioning deviation occurs, particularly in high-power applications, which include electric vehicles or industrial equipment. This results in user experience challenges while reducing the practicality of wireless systems relative to plug-in techniques that operate with increased consistency.
