It is a long-term challenge to replace human resources with artificial equipment of the same ability and efficiency. It is the most advanced prosthetic arm, but it can not achieve the complexity, flexibility and adaptability of human hands. At present, we can see the upper limb prosthesis system, which can only be called a tool, but not a substitute for the lost arm or the lost hand. < / P > < p > in the cover of the latest issue of science robotics “scientific robots”, IIT Laboratory of the Italian Institute of technology shows a newly developed bionic hand Hannes, which not only has a very similar appearance to human hands, but also can restore more than 90% of the functions of amputees. Its design concept has also been awarded the compasso D & ා 39; Oro International Industrial Design Award. < p > < p > the bionic hand Hannes is a kind of upper limb prosthetic system including hands, wrists and other joints. It is characterized by good flexibility and the ability to dynamically adapt to the shape of the object to be grasped. < / P > < p > in order to evaluate the effectiveness and practicality of Hannes, the researchers conducted experiments on amputees of upper limbs, and found that amputees could use Hannes for daily activities at home in less than a week of training. < / P > < p > in 2013, Istituto Italiano Di tecnologia (IIT) Laboratory of the Italian Institute of Technology launched a series of projects aimed at developing innovative and cost-effective high-tech bionic devices for patients with physical disabilities. < p > < p > the bionic hand, which was designed jointly with researchers, orthopedics doctors, industrial designers and patients from prosthen prosthetic Department of the National Industrial Injury Insurance Institute of Italy, is the latest research achievement. < p > < p > the bionic hand that has been researched and commercially sold in the past has either high performance but high price, or low price. Although it is strong and durable, it has limited versatility and poor aesthetic effect. Compared with the above bionic hands, this bionic hand “Hanes” is not only easy to operate, strong, low cost, but also comparable to the hand grip strength and appearance, showing its excellent performance. < / P > < p > Hannes bionic hand is an EMG system, which can be adjusted according to different degrees of upper limb injury. A series of sEMG sensors placed in the custom socket can detect the muscle activity of the patient’s residual limbs, and the patient can perform various operations by actively contracting the muscle. < / P > < p > in addition, researchers have developed specific software and Bluetooth connections to customize the operating parameters of the Hanes bionic hand, such as the accuracy and speed of movement, so as to provide the best experience for each patient. < / P > < p > the bionic hand can be worn by patients for a whole day (with a maximum battery life of 1 day and a capacity of 1300 MAH), and has been tested for durability and robustness (nearly 500000 life cycles) in an environment that has been used for more than 1 year. < p > < p > Hannes bionic hand is the strongest in its mechanical design, and is far ahead in the current market field. The mechanical differential system makes the Hanes bionic hand use only a single motor to grasp the object, and the efficiency of the system is consistent with that of the human hand. This design gives the Hannes bionic hand a natural feel, while its function is greatly increased. < / P > < p > currently, the Hannes bionic hand weighs 450 g and has two sizes of right hand and left hand, which are suitable for female and male subjects respectively. < / P > < p > in addition, the finger and wrist movements of the Hanes bionic hand are also very flexible. The fingers can bend and position naturally when they are still. Among them, the thumb can be positioned at three different positions to adapt to a variety of grasping operations, including fine grasping of picking small objects, lateral grasping of holding small objects, and strong grasping of grasping and moving heavy objects. The overall grasp is effective and robust. < / P > < p > the bionic hand can also make the wrist make key rotation movements, such as forward rotation and backward tilt of the wrist. In this way, the Hannes bionic hand can grasp in different directions without damaging the patient. In addition, Hannes bionic hand has a very fast grasping speed. It can complete the complete closed grasp in less than 1 second, and the maximum grip force can reach 150n, which is far more than other research and commercial “bionic hands”. < / P > < p > at present, the iit-inail patent application contains the basic principle and design of Hanes bionic hand. Moreover, the Hannes bionic hand already has a “license” for commercialization and international sales in the European market. Currently, researchers are looking for investors and companies to industrialize the Hanes bionic hand on a large scale to benefit the disabled. Privacy Policy
