The Future of Prosthetics

Posted by on Sep 2, 2016 in Uncategorized |

Prosthetics have come light years from the days of Captain Hook and more advances are around the corner. As of now, researchers have been able to develop prostheses that are owner-controlled in various ways, but they are still imperfect.

Researches from The United States and Korea developed a synthetic skin (actually a polymer) fitted with an array of silicon and gold sensors to imitate how real human skin functions (stretchability, sensory capability).

Silicon is normally not a stretchable substance so it has to be constructed in a specific way to allow for expansion. Sensors in such a “skin” need to be positioned correctly depending on each one’s location on the body. In this study, researchers made a detailed study of the human hand and where it stretches when flexed to determine where to place the sensors.

This is only the first step in the evolution of sensory artificial skin. As of now, one of the biggest challenges is how to connect it successfully to its owner. Establishing a connection between the sensors of this “skin” and the human brain is in its infancy. We’re not near the point where the wearer of such artifical skin can, in fact, “feel” what’s being touched or handled.

Studies in Korea with rats did show some reaction in the rats’ brains to sensory input, but there’s no way yet to gauge qualities like moistness, heat or cold.

One study which met with some promising initial results allowed an amputee to pick up objects (including softer items like fresh cherries) with the right amount of pressure, avoiding crushing of the fruit. This early trial conducted at the Cleveland Veterans Affairs Medical Center was reported on by MIT Technology Review.

While there is still much to be done, this area of medical research is already yielding exciting results. Technology advances in fits and starts, but ultimately the goal is reached. How long until a real, viable “smart skin” becomes available? Unknown, but the future does indeed look good.

Science Fact: Advances in ocular technology

Those of “a certain age” will remember the television show “The Six Million Dollar Man” starring Lee Majors. Aside from bionic legs and arm, main character Steve Austin also sported a bionic eye. It allowed for close up views from great distances. While it was science fiction at the time, things have changed and fiction has become fact. At least to a degree.

The Argus II is one such medical breakthrough. This device transmits a wireless signal from sunglasses equipped with a special camera to retinal implants in an otherwise sightless patient. While it has been in use since 2011 in Europe the Food and Drug Administration recently approved its use in the United States.

new advances for retinal pigmentosisThe “eye” does draw comparisons to Star Trek: The Next Generation’s Geordi La Forge (played by Levar Burton). In the series La Forge used wrap-around “shades” to see. Without them he was blind.

However, the Argus II does not (yet) pack the power of La Forge’s sunglasses, but can restore some limited vision to the blind. It allows for general distinguishing of light and dark. It can allow a formerly sightless person to make out single words on a mobile device like an iPad, providing the text is extremely large.

It is currently approved only for those who suffered from retinal pigmentosis and lost their sight to this disease. Drawbacks may include decreased vision over time due to the fact that a person’s retina will heal, covering the implant.

Retinal pigmentosis (or RP) RP is inherited and depends on a person’s parents—whether one or both are carriers for the gene. It is estimated that about 1 out of every 4000 people may contract this disorder.

Regardless, the Argus II is an astounding breakthrough that Steve Austin would applaud and may help restore a degree of sight to those affected by other ocular diseases in the future.

Cancer Death Rates


Disease is the explanation behind roughly 14.6% of every single human demise. Growth is an illness that influences all individuals and happens all around. Shockingly, there is still no cure for some writes of malignancy, and we can’t spare individuals have disease. Still, we ought to know that the most well-known sorts of tumor in guys are lung growth, prostate disease, colorectal malignancy and stomach disease.

With respect to the females, the most well-known sorts of disease that influence females are bosom tumor, colorectal malignancy, lung growth and cervical tumor. Tumor additionally influences kids.
