Students from Sydney and London have developed an amphibious prosthetic limb that lets wearers run on sand and swim full speed in the sea.
The Murr-ma limb has a split-toe design that helps a user balance on the uneven terrain of a beach and has studs that give a larger surface area when running on soft sand.
When worn in water, Murr-ma has 'fins' fitted at the top of the prosthesis that channel the flow of water along the limb and propels the swimmer faster - and this can give wearers more thrust and faster speeds than able-bodied people.
