SmartArch orthodontic archwires, the first application of MMM smart materials technology, are programmed to deliver ideal force to each tooth. Applications to other medical devices are in development.

We’re unlocking the true potential of these smart materials to function as machines

Smarter Alloys, a smart-materials engineering company, today announced that it has been awarded patents on its innovative Multiple Memory Material technology by the United States Patent Office and the Chinese Patent Office. The patent covers Smarter Alloys’ method for programming more than one memory into shape memory alloys, making it possible to closely control the unique properties of the material.

Shape memory alloys are special metals that can remember their original profile. If they become deformed, heating them will prompt them to spring back into shape. Until recently, however, these alloys have been limited to just one memory.

Smarter Alloys’ Multiple Memory Material technology changes that — promising to revolutionize medical devices such as stents and catheter guidewires. It enables designers to tune the local properties of different sections of a device, offering a new dimension of control.

The first commercial application of the technology is in the orthodontic archwires used for braces. SmartArch wires are programmed to provide biomechanically optimized forces to match the needs of individual teeth, resulting in optimized treatments and fewer visits to the orthodontist.

“For us, it’s about pushing the boundaries of shape memory alloys to develop the devices of tomorrow,” said Dr. Ibraheem Khan, CEO of Smarter Alloys and co-inventor of Multiple Memory Material. “We’re unlocking the true potential of these smart materials to function as machines. Our technology opens a new paradigm for devices with enhanced functionality enabled by this additional element of control.”

Beyond orthodontics, Smarter Alloys is actively developing applications of the technology for other dental devices, medical devices, robotics and automotive applications, to name a few. Several additional patent applications have been filed and are expected to be granted over the coming years.
