Flexible microbattery enables smart dental braces

Researchers have demonstrated a novel approach toward smart orthodontics based on near-infrared red light from a mechanically flexible LED powered by flexible bio-safe batteries all integrated in a single 3D-printed dental brace. Integration of electronic devices in 3D printed dental aligners is a pragmatic approach towards implementing a flexible electronic technology in personalized advanced healthcare, particularly in orthodontics. Key to this smart brace is the use of a high-performance flexible solid-state microbattery.
