Differences is what makes people unique. But what if being different is the reason for someone’s unhappiness, what if being different causes someone to want to be the same? In the short story Hands, written by Xiao Hong, a girl who is different from the rest of her peers at school is mocked and dehumanized. The story takes place in the early 20th century in northern China. The girls name is Wang Yaming and her hands are much darker than the rest of the girls because she is a dyer, someone who dyes cloths. Everyone else at school comes from cities and homes with financial stability while Wang Yaming comes from an impoverished area in the rural side. People such as the principal, the girls at the school, and even Wang Yaming’s father all either pitied her, believed she wouldn’t outcome to much, or relentlessly criticized her. The majority of people judged her before getting to know her and her life because of the time and setting of the story was set during a time where people were more close minded because they were not used to being with different people and different ideas, which caused the characters of the story to see the world one sided.

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.

In the short story “Hands” by Xiao Hong, the main character, Wang Yaming, experiences this sort of pain in her boarding school. In this story, the main character is being tormented by students and staff because of her black, stained hands. Her hands are this way because, she is the dyer’s daughter and wants to make ends so she can afford to go to school. When fellow classmates and the Principal of Wang Yaming criticized her for her hands, it made depictions of how people will treat you unfairly because of your flaws. Judgment towards someone based off of looks is unacceptable, since you don’t know who the person really is.

Chimps for example, have similar hands to humans, however, when using a hammer stone, they frequently use a power grip where all fingers are used to control nut-cracking (Wong, 2004). Here, their finger proportions inhibit easy coordination between the index finger and thumb (Wong, 2004). This is significantly different to that of hominids who have hands and thumbs which are very effective and allow for precise knapping and control over hammer stones. This illustrates that their differences in physical characteristics lead to distinctly different behaviors that cannot be considered the

The second design exercise involved me exploring more into the possibilities of using the laser cutting technology for 3D scanning with different drawing software. In this exercise, I made a small replica of my hand doing a classical Indian dance gesture, ‘Hamsasya’. This was done by scanning my hand using a ‘structure sensor’ device in which was attached to an ipad and examined around my hand.

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

The hand is a very important extremity attached to the human body and is used in everyday life. Humans use it doing almost everything. The major systems the body uses to be able to move the hands are the skeletal, muscular and nerves systems. The skeletal system of the hand involves the bones, such as, eight carpal bones, five metacarpal and fourteen finger bones (Istitute for Quality & Efficiency in Health Care, 2013). All connected by joints and ligaments. The muscles include two parts, the thenar eminence and the hypothenar eminence (Istitute for Quality & Efficiency in Health Care, 2013). The thenar eminence moves the base of the thumb, also lets the thumb touch the four fingers; the hypothenar eminence allows the little finger to bend

When a person loses a limb, it is never a clean cut; whether it be the remnants of gore from the cut, the trauma of the loss, or the non-physical remnant of the limb itself, known as Phantom Limb Syndrome. Despite effecting 80% of all amputees, the sensation itself continues to mystify neuroscientists and is not yet fully understood. The most popularized type of phantom are the painful ones, seeing as it affects 50-80% of amputees regardless of whether their amputation was traumatic or done in a hospital for their health, but phantom limbs are not all painful and can come in many shapes, sizes, and types of sensations.

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

Hand: Intaglio is a form of hand printing, this involves using many different elements throughout the process. First you use a metal plate, this then covers the surface in copper with a roller, and this is to protect the plate from the etching process. The next element within this process is to start the design of the printed piece. This is done by using specially designed needles made of steel, they are made out of steel so they do not react with the metal used on the plate. You will then start to use the needles to uncover the copper below the protected surface, this then will become your design. Once the print has been finished, the sheet of metal is placed in an acid bath made with nitric acid. The longer the plate is left within the acid the more detailed the finished product will be, when handling the metal plate near the acid, protective clothing must be worn. The acid used can burn through skin if not

Take a second, and imagine your life as a teenager, fresh out of college with, aspiring to get a degree in whatever your heart desires. You’ve got lots of ambition and potential. The world is at your fingertips; you can do anything you set your mind to. But one day, tragedy strikes and the unthinkable happens: you lose a limb. Why is not important, but what the future entails is. Let’s say this limb is your right arm, the one you have used all your life to write, eat, type and play the guitar. Now let’s change the scenario a little bit. Instead you’ve lost your legs in a horrific car accident where both were crushed under the weight of the dashboard as your car collided with the 4x4 in front of you. You wake up the next day in the hospital groggy, barely remembering what happened. Shock is the only thing running through your mind the moment you look down to see your legs missing. Your brain thinks they’re still there because yesterday you were just getting out of bed for your morning jog. All that remains are the stubs where your legs used to be and the unbearable thought of being confined to a motorized chair for the rest of your life.

In prescription, prosthetic limb is a fake gadget that replaces a missing body part. The procedure of making this known as appendage prosthesis. It is a piece of the field of bio mechatronics, the study of utilizing mechanical gadgets with human muscle, skeleton, and sensory systems to support or improve engine control lost by trauma, ailment, or deformity. Prostheses are ordinarily used to supplant parts lost by harm (traumatic) or absent from conception (intrinsic) or to supplement imperfect body parts. Inside the body, manufactured heart valves are in like manner utilization with simulated hearts and lungs seeing less normal utilization. Other therapeutic gadgets and supports that could be considered prosthetics incorporate amplifiers,
