The MyLeg project aims at developing both a solid theoretical understanding and the enabling technologies for the realization of a new generation of transfemoral prostheses that can be intuitively operated, sensed, and trusted as the healthy counterpart. MyLeg introduces the concept of smart and intuitive osseointegrated transfemoral prostheses that embody advanced dynamic behaviors.
The MyLeg prosthetic system will be directly anchored to the amputee’s bone by means of osseointegrated implant to enhance the human-prosthesis interaction, perception, and motion capabilities; it will include implantable myoelectric sensors on targeted reinnervated muscles to realize an intuitive EMG control and to provide a high-level of cognition abilities; it will implement variable stiffness actuators realized with stress-stiffening nanostructured materials that guarantee high adaptability with respect to different tasks, dependability, and decisional autonomy; it will exploit light-weighted nanofibrous materials for sensing and energy harvesting.
Expected impacts:
- MyLeg will have a societal impact. Transfemoral amputees will better accept the prosthesis, their quality of life will improve, they will reach a higher degree of self-reliance, their social contacts will be enlarged, their (re-)integration in the society and in the labour-market will be facilitated.
- MyLeg will have an economic impact. Transfemoral amputees will need less support by formal/informal caregivers, which will reduce the burden on these groups and on society as a whole.
- MyLeg will impact the leadership role of Europe in the prosthetic market and, more in general, in the robotic world.
Objectives:
MyLeg will develop a new generation of powered transfemoral prosthetic legs that can be intuitively operated, sensed, and trusted as the healthy and reliable counterpart for a variety of tasks. The main objectives of the project are:
- To enhance human-prosthesis interaction, perception, and motion capabilities by exploiting osseointegration.
- To provide an intuitive control and to extend the user’s cognitive capabilities by using implantable myoelectric sensors on targeted reinnervated muscles.
- To achieve energy efficiency, dependability, and adaptability to different tasks by designing novel variable stiffness actuators and composite materials.
