Advances in wireless flexible electronic devices for rehabilitation medicine

Against the backdrop of global population aging, rehabilitation medicine has become an indispensable component of healthcare systems. Conventional rehabilitation frameworks predominantly operate within hospital-centric ecosystems, where fixed-position equipment is a fundamental component. However, future rehabilitation will prioritize remote home-based treatment systems, necessitating wireless flexible electronics. Therefore, further review and exploration of the principle, preparation methods, and application for wireless flexible electronic devices is of great significance for the field of rehabilitation medicine. This review features a comprehensive account of the latest advancements in wireless flexible devices for rehabilitation medicine. Wireless power supply technologies applied in flexible devices, including batteries, electromagnetic field energy, and environmental energy, were first introduced in detail. Subsequently, a detailed analysis was conducted on the development of wireless data transmission technologies, including radio frequency identification, near-field communication, Bluetooth, and resonant antenna technology. Then, the applications of wireless flexible devices in rehabilitation medicine are reviewed from four aspects. Finally, we summarize the current weaknesses and limitations, and further outline our own views on the future development direction and industry trends. We believe that the advancement of design and preparation technology of wireless flexible devices will bring new creative points for future rehabilitation medicine
