Biomedical engineering, a great job
Who are biomedical engineers? What is your work in society? What does the technology work? The work of biomedical engineers is very important both in medicine and in all branches of electronics, because every step you take these specialists technology improves mechanical devices replacements for body parts.
Biomedical Engineering
What is the Biomedical engineering?
The Mexican Society of Biomedical Engineering mentioned that this specialty training includes technical and administrative tools to facilitate and improve health care. Its importance lies in the knowledge of mechanics, electronics, instrumentation, medicine, administration and others, which together can perform highly specialized tasks.
The biomechanics is a science that is based on principles and laws of physics, which helps the understanding of biological mechanisms, in addition to the physics involved also the physiology, anatomy, mechanics, mathematics and engineering, with which aims to explain the behavior of living systems, and solving the problems caused by the different situations they are subjected.
How to help society?
Biomedical engineers help much, since all these disciplines, specialists have given the best tools to replace a limb or organ or maimed amputee of a human body. The intent of biomedical engineers is that people without a limb, make your everyday life with a machine that fully merging them.
Current technological advances: bionics
The machines used to replace a member of the body are called neural prosthesis or bionic, a term popularized by science fiction. Todd Kuiken , a physician and biomedical engineer, was responsible for starting the term “bionic” to baptize a mechanical arm, with which it began to change the characteristics of the prosthesis, turning a new generation. The new function prototypes prototype obeying signals transmitted to the brain to function either as the original.
Bionics is the study of mechanical systems that function like living organisms or parts thereof. Bionics has an etymological meaning bios (life) and Onyx (e) , ie electronic life. Bionics is a breakthrough that allows researchers to give back to people as never before possible, much of what they lost in a member of his body.
Bionics in Action:
Doctors engineers have worked with prototypes from different parts of the body to become more real parts. This happened with a bionic arm positioned at a Tennessee woman named Amanda Kitts.
“After my accident I felt lost. Now I’m excited because I continue to improve the mechanical arm”, says the wife of 40 years. Specialists have given life to a prototype arm to reach it as sensitive as the original features have varied as the medical breakthrough:
* The human arm, has twenty or more movements from the shoulder to the last joint of a finger, an arm has at least 22 moves. The nerves carry instructions from the brain from the spinal cord to the muscles.
* The traditional prosthesis: three movements. The prosthetic hand clamp is still the only device available for most amputees.
* Proto 1, has seven movements. The nerves that once came to the forearm are diverted to other muscles, where electrodes are placed to capture orders from the brain and transmitted to the prosthesis through the cables.
* Modular prosthetic limb, has up to 22 moves. The nerves of the spinal cord send orders from the brain to the array of electrodes implanted in the residual nerves. A computer chip in each parent transmits information wirelessly to a receiver on the skin. The receiver connects information with another chip, which decodes the command and sends it to the driver member in the palm, which starts the engines.
In addition, you plan the design of bionic skin in 20 years for the bionic hand has the highest possible sensitivity with which the temperature can feel and touch. In addition you could also benefit burn victims in a project with NASA FILM skin.
Experts Speak:
“We give people better tools than they had before. But there are rudimentary, like a hammer compared to the complexity of the human body. They are a candle compared to the glare that is Mother Nature”,says Dr. Todd Kuiken.
“It is expected that the biomedical engineering jobs will grow faster than average for all occupations in the coming decades, as demand for better systems and medical equipment will increase in coming years”, according to the Bureau of Labor Statistics, U.S. Department of Labor, Occupational Outlook Handbook. Washington, USA, 2001.
