V. The Politics and Public View of Prosthetic Rehabilitation

         There is no real controversy between the use of prosthetics and politics. The only issue that slows down the release of prosthetics is the time it takes for the government to approve the prosthetic to be distributed to the public. However, like all medical treatments that is understandable. You wouldn’t want the FDA to release a medicine that has detrimental side effects. Same goes for prosthetics; an artificial limb may malfunction and do something harmful like uncontrollably increase the grip when holding something delicate such as a baby or the battery may be corrosive and may harm the user. Usually these issues are not a problem for artificial limbs but as stated earlier in this blog prosthetics aren’t only artificial limbs. Most prosthetics that take a long time to be approved by the government usually require very invasive surgery like brain-computer implants or artificial spinal nerve biofilm. 
         Another thing that thwarts the release of a prosthetic to the general public is funding. Funding is highly essential for prosthetics. Usually the development requires a lot of money due to moving parts, development of miniaturized computers, animal experiments, and human prototyping models before the actual human experiments. In the case of an artificial limb, a limb may cost thousands of dollars. The prototype must be developed and fine-tuned before through experimentation before it may be made for human experimentation.

         I couldn’t imagine the public having an issue with the development of prosthetics. I would imagine the only thought that would cross an individual’s mind when seeing a prosthetic is a sense of curiosity of how the disability may have occurred or how cool the prosthetic is. Besides the restoration of function to the prosthetic user I believe patients psychologically feel a sense of relief their disability no longer singles them out from the general public.

IV. Journal Review: Tactile prosthetics in WiseSkin

The journal “Tactile prosthetics in WiseSkin” was published in the Date ’15 Journal of this year. This paper explores the answer to one of artificial limbs’ major issues; the inability to assess pressure exerted by the prosthetic controlled by the user. Prosthetic.
            This issue effects the users ability to grip objects with a prosthetic hand or allow the user to receive incoming information about objects touching the prosthetic.
            This journal works to determine the proper amount of tactile receptors should be placed around a prosthetic and the development of a wireless sensor that operates on low power usage that can be embedded in artificial skin undetected. Sensors developed must be able to send signals to the user through the use of a sensor node that can be invasively implanted into the user’s brain or strap on to the users arm.
            The smart skin or “Wise Skin” is produced in sheets composed of several layers, one layer being full of electrodes and others as protective layers to support the electrode sensors and protect them. The skin is then fitted on a prosthetic hand or leg to give tactile information to the user.
            In addition to tactile sensation the development of an electrode sensor that can detect temperature is currently taking place by the same company. The invention of this technology is restoring all function of a normal limb to the prosthetic user.
