Research engineers at Saarland University and medical researchers at the Saarland University Medical Center are developing smart implants that can both monitor and promote healing in fractured bones. When installed at the fracture site, these implants, which are constructed using shape memory alloys, can stiffen or relax in a continuously controlled manner that optimizes bone healing. As part of an EU-funded project, the researchers are miniaturizing the technology for use in thin intramedullary nails (IMNs), which provide internal support and stability during the healing process. The team will be demonstrating this medical technology at Hannover Messe from 31 March to 4 April.
