In order for the bionic prostheses of the arms and legs to allow patients to feel completely free in movements, they should not only be made of durable and lightweight materials, but also work according to the neural principle, without any wires. It was such a project of a unique bionic leg that was demonstrated today by a team of mechanical engineering specialists at the University of Utah, under the leadership of Professor Tommaso Lenzi – the project has already been tested by one person who described the experience of using the prosthesis as “the experience of the Terminator” from the film series of the same name, which clearly indicates a high degree of convenience and flexibility of the prosthesis.
It is not surprising, since the prosthesis itself is made of a special alloy of titanium and aluminum, thereby providing ease of lifting – after all, the design weighs only 2.7 kg – and higher strength, in comparison with many similar models. In addition, the bionic leg model boasts a truly rich set of sensors of a variety of formats and types – from standard accelerometers to specialized rotary thrust sensors.
Considering that this rich set is controlled by a special processor chip at the base of the foot structure, it becomes clear why the tester described his experience in this way – because the prosthesis has the ability to automatically adjust to the rhythm and features of walking, as well as take into account the objects surrounding it in the air and on land in order not to create any problems for its carrier related to movement. However, the project itself is still undergoing preliminary testing and will be frozen for some time.
However, the team of mechanical engineering specialists from the University of Utah – as well as Tommaso Lenzi himself – is confident that very soon she will present the final version of her new bionic prosthesis, which will delight even more advanced functionality and the ability to more intelligently and quickly adapt to some features of the wearer. However, one can only guess whether the development will enter the mass commercial market and how much it will cost if anyone wants to buy it.
