Acclaimed Brazilian pianist João Carlos Martins had not played with ten fingers since he lost the use of his right hand in a 1995 mugging in Bulgaria. But today he has returned to play his favorite Bach sonatas thanks to "bionic gloves" invented by industrial designer Ubiratan Bizarro.

"When he showed me the gloves, I joked that they were for boxing, not to play the piano again," Martins, 80, said of the black neoprene gloves made by 3D printer.

The gloves have rods that make the fingers spring back into place and allow the pianist to continue playing the keys.

Martins performed with leading orchestras in the United States and Europe and recorded Bach's complete keyboard works, but the injuries ended his career.

For many years he played with one hand and a thumb, but lost the use of the left hand due to focal dystonia, a neurological condition affecting the muscles.

"To be able to use all ten fingers again after more than 20 years is a miracle for me at the age of eighty," he said.

Bizarro says he got the idea from Formula 1 motor racing technology.

He spent less than $100 to make the first pair for Martins and now exports them to Europe under the brand name Bionic Extender Gloves.
