DESIGN AND FABRICATION OF SARCOMERE-LIKE ELECTROMAGNETIC ACTUATOR PROTOTYPE FOR ANTHROPOMORPHIC HAND Sarcomere (Fig 1) is the basic unit of striated muscle tissue. Skeletal muscles are composed of tubular muscle cells (myocytes called muscle fibres) which are formed in a process known as myogenesis. Muscle fibers are composed of tubular myofibrils. Myofibrils are composed of repeating sections of sarcomeres, which appear under the microscope as dark and light bands. Sarcomeres are composed of long, fibrous proteins as filaments that slide past each other when a muscle contracts or relaxes. Fig 1. Sarcomere A muscle fibre from a biceps muscle may contain 100,000 sarcomeres. The sarcomeres are what give skeletal and cardiac muscles their striated appearance. An Electromagnetic actuator is designed to imitate this mechanism of sarcomeres. This artificial sarcomere consists of three parts. Two alpha segments and one zeta segments. The structure of an artificial muscles is s...
