Prosthesis is a term used for replacing a human body part which has been damaged or cut accidently with an artificial one. Hybrid prosthetic limb is a combination of mechanical and electrical circuit in which a controller gives command to electrically driven motor for the gripper opening and closing. Signal for the gripper opening or closing is acquired from the other shoulder movement. A strap on the shoulder is tied to a string which switches on or off the limit switch to give a trigger signal. This trigger signal actuates the motor in the gripper to perform open or close operation.

A major impetus to improving artificial limbs started when the United States encouraged companies to improve prosthetics instead of munitions (Norton, 2007). The combination of lighter materials and robotics assist has created huge advancements in functionality and has dramatically improved quality of life and potential for independent living. Even with the advancement of these limbs, the basic mechanical principals are still the same. Modern times allow for many different types of limbs to be created. Limbs can be created to match skin tone, freckles and fingerprints. There are three many ways a limb can be made to move. The first is attaching the limb to a moving body part to act as a gear shifter. Another variation is a motor attached and the person can switch modes by a mechanical toggle shift. The most advanced movement is the myoelectric capability. This is when electrodes are placed on the muscles of the residual limb. When contracted the arm will move according to which electrode fired. A microprocessor can also be attached to learn exactly how the person walks (Clements, 2008). Modern prosthetics offer valuable life skills, yet are very

Modern prosthetic limbs have become very advanced in the last decade. They now have the ability to grip objects, have running limbs, and many more wonderful things. Although these prosthetics are great, they are lacking some key extras that amputees would relish. What amputees really want is their sense of feeling back. They want to reach out with their prosthetic limb and be able to tell if the stove is on or off. They want to be able to press the gas of an automobile. This sense, that all non-amputees take for granted, would be a great place to start the improvement of the perfect prosthetic limb. To accomplish such a daunting task, engineers must figure out an alternative source that could interact with the amputees still intact nerve endings. This way they can use their still functioning nerves to communicate with their pseudo-nerve and have the ability to move their prosthesis around with complete control of it and its sense of touch. I believe this has not

Within the human anatomy, an intricate and complex network of specialised nerve fibres and neurons works in collaboration with the central nervous system and peripheral system, designed to carry out the various actions humans perform every day. The nervous system is also known as the master control unit of the human body, as it operates other major functions such as the circulatory and respiratory systems (Jakab, 2006). It is composed of the central nervous system (CNS) and the peripheral nervous system (PNS). The neurons established within the various sections of the nervous system, is structured with three main parts: a dendrite which is a cluster of branches that operates by receiving information from the

sophisticated electronics to let the nerve and muscle systems of the human body to be able

The potential to create exceptional, innovative products through the use of electrical engineering and embedded systems have always fascinated me. From the miniaturized circuit boards in smartphones and tablet PCs to the large-scale embedded electronics used in aerospace systems (Bozzano, Cimatti, Katoen, et. al., 2011) electrical engineering has long fascinated me. One of the most significant factors that led to my passion for this subject is the revolution that is occurring in the areas of mobile processors, avionics and aerospace systems, where embedded systems are critical to the navigational integrity of the vehicle. This revolution in embedded systems is also leading to an entirely new era of performance in avionics and deep space exploration, which promises to deliver insights never learned before from previous technologies (Kadayif, Kandemir, 2005). Due to all of these factors I am extremely interested in electrical engineering and pursing it a graduate degree in this academic discipline .
