Smart Braces LED Battery

Researchers from King Abdullah University of Science and Technology (KAUST) have developed an orthodontic system that uses smart 3D printed braces and flexible, non-toxic batteries. The system consists of a semitransparent, 3D printed dental brace that places two near-infrared LEDs on each tooth, along with one lithium-ion battery to power the LEDs, which provide localized light therapy to the teeth. The redesigned state-of-the-art lithium-ion battery technology are flexible with biosafe encapsulation within the braces to make a smart dental brace.
