A new prosthetic foot that allows women amputees to wear high heels
For the first time, a non-custom prosthetic foot called 'Prominence' has been developed that will allow women amputees who have lost a leg to wear heels of up to four inches in height. Mechanical engineering researchers from the Johns Hopkins University in the U.S came up with this idea after they realised that women amputees currently cannot buy non-custom prosthetic legs that will adjust for high heels.
The researchers tried many materials for building the prosthetic foot including balloons and titanium plates. Finally, they used a 28-layer carbon fibre footplate for the base of the foot and a special hydraulic unit for the ankle that gave a smooth movement and flexibility to the foot. The design of the prosthetic foot 'Prominence' and its potential as a product are still being studied.
