چکیده
During the past couple of decades , energy from human body motion has been sx-plored extensively to provide electricity needed for energizing cell phones and other gadgets. In this paper, an optimized design of a suspended-load backpack with a mechanical motion rectifier (MMR) is presented. The system parameters were obtained for producing maximum output power with an 8-kg backpack, which is the lightest proposed in previous studies. Simulations show that 6.92W of electrical energy can be harvested from human walking. Alongside the numerical simulation, some experiments were conducted to verify it. A prototype of the backpack is fabricated, and a maximum average power of 4.37 Watts and instant power of 11.57 Watts were obtained by onesubject while walking with normal walking speed, carrying the MMR-based backpack harvester and 8 kg of the load mass. This power is the most average output power with normal walking speed and the payload of 8 kg among previous studies.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
