Cure Bionics 3D-printed prosthetics are lightweight and muscle-controlled. They can be attached without surgical intervention and are charged wirelessly by solar power. The arms can be printed and ready within a week at the cost of just $3,000. Other providers can take months and charge up to $100,000. Cure Bionics’ arms are available for children with limb differences aged 8 and up. The low weight makes them easy for kids to operate. An immersive VR training programme helps patients learn to use their arms even before it’s made. Cure Bionics was founded in Tunisia, where the start-up has already launched a prototype. In spring 2023, it’s releasing a public version.
