Italian researchers develop a hand prosthesis that performs the functions of the human arm … Photos


An Italian team developed an artificial limb, able to replicate the main biological characteristics of the human hand with adaptive movement and biomimetic levels of strength and speed. After a training period of less than a week, patients could use the “Hans” limb independently to perform activities of daily living. techxplore Technology specialist.

The Italian team confirms that the new arm is able to perform more than 90% of the normal functions of the arm, to help people who have had amputations in their upper limbs, and they mentioned in the scientific journal, “Science Robotics”, which specializes in robotics research, that the prosthetic arm can be worn throughout the day, It can be modified, so that it matches different forms of amputation, and it is also equipped with a series of units of measurement to sense movement in the remaining part of the muscles of the amputated limb.

The prosthesis is a muscular electrical system that can be worn throughout the day and is adjustable for a variety of conditions of upper limb weakness. A set of surface electrical sensors placed inside a dedicated socket detect the activity of the remaining limb muscles in the lower or upper arm.

The robotic hand “Hans” was developed in Italy and its true intelligence lies in the mechanical design, which is completely unique in the market sector, and gives the prosthesis versatility and natural hand movement.

Fingers can be flexed and positioned naturally, even at rest, in particular, and the thumb can be guided in 3 positions to repeat a variety of grips, including the precise grip for capturing small objects.
