Scientists have created an inflatable robotic hand that costs a fraction of more rigid prosthetic limbs and gives amputees real-time tactile control. The pliable design, which bears an uncanny resemblance to the inflatable robot in the animated film'Big Hero 6', includes five balloon-like fingers attached to a 3D-printed'palm' shaped like a human hand. Its creators are particularly excited because the parts cost around $500 (£362), making it much more affordable than other bionic limbs that can cost tens of thousands of dollars. The pliable design includes five balloon-like fingers attached to a 3D-printed'palm' shaped like a human hand Prosthetics that attach to part of the human body are often objects that allow a person to perform a specific function - such as blades for running. Scientists are working to develop prosthetics that are personalised and respond to the commands of the wearer.
