Peshawar: A team of researchers in Department of Mechatronics Engineering, University of Engineering & Technology Peshawar in collaboration with Pakistan Institute of Prosthetics and Orthotics successfully developed a two degree-of-freedom prosthetic hand. Using Force Myographic solution and the hand can respond intelligently. The amputee, in fact, just like a real hand, can pick up the things by just thinking of the desired motion. Advanced actuators are used in the prepared hand and mapped with the brain signals which allow users to perform daily living activities in a more natural way. The prosthetic hand is not only capable of flexion/extension (opening/closing) of hand but also contains one more degree of freedom as wrist joint turning to enable a disable to accomplish the intentional jobs. According to the team, from control perspective, the researchers developed a new method to acquire muscle signals of amputees. In existing practice most of the prosthetic hands internationally utilizes Electromyography (EMG) electrodes to capture muscle signals. However, EMG has certain disadvantages associated with them including high cost, fluctuations and unwanted noise in the signal, because of which they require essential signal processing resulting in a lag between muscle input and actuator output. To address these issues, the team has successfully developed a new method of acquiring muscle signals through force myographic approach, in which force sensors detect muscle signals. This makes the system more cost-effective, highly accurate, fast and robust as first time in the world.

The Vice Chancellor of University of Engineering & Technology, Peshawar Professor Dr. Iftikhar told that the research was initiated six years ago as a challenge and despite of limited budget was thoroughly financed by the university itself. The project neither funded by any government department related to Science & Technology nor by anybody else however in order establish a manufacturing unit for production, investor or a keen industry requires to the Institute, he added. Dr. Iftikhar said that in today’s technological and practical era the categorization of institutes should be based on such commercialized products development towards sustainable manufacturing units. The Vice Chancellor also viewed that these types of researches of commercialization if facilitated by the government can play a vital role in unemployment problem and enhancement provincial economy.  The team of researchers comprising of Dr. Izhar-ul-Haq, Associate Professor, Dr. Kamran Shah and Engr. Muhammad Usman Qadir told that they intend to treat further patients with this new ground-breaking technology over the next few months. And these hands will soon be indigenously mass produced with the help of investors, public private partnership or a grant of Rs. 80 millions approximately require for this project. Dr. Izhar-ul-Haq said that despite of technological advancements, Pakistan is still facing lack of indigenous solutions in the field of prosthesis and orthosis. Prostheses are an artificial device that replaces a missing body part, which may be lost due to several reasons including trauma, blood vessel diseases and accidents etc. He also said that research is going on and in the near future this prosthetic hand will be improved to a Seven Degree of Freedom that will enable an amputee to count or to keyboard typing like a normal person. The researchers added that they are ambitious about their one new project on human knee development that will treat those patients who are missing their legs or knee. This
