Vigyan is here again…………
The TechnoCracy (Technical Committee) of NIT Raipur brings you Vigyan……
Vigyan invites participants from various branches to apply their domain specific knowledge to the problems for the betterment of Human society…..!!!!
Here are the problem Statements for Biomedical Engg. Domain:-
1. Design a Blind Stick285 million people are visually impaired worldwide according to WHO statistics. A huge chunk of this people lives in the developing world. Scientists and engineers all over the world are going beyond the boundaries of their disciplines to innovate and come up with solutions for addressing the needs of the visually impaired people. The challenge is to design a path navigating stick to guide the visually impaired patients.

What are Neurosprosthetics?
Neuroprosthetics (also called Neural Prosthetics) is a discipline related to neuroscience and biomedical engineering concerned with developing neural prostheses, artificial implantable devices to replace or improve the function of an impaired nervous system.Neuroprosthetics are the set of physical devices that interact with the brain or other neural tissue to augment, restore, or otherwise impact function.
Neuroprosthetics are electrical stimulation technologies that replace or assist damaged or malfunctioning neuromuscular organ systems and attempt to restore normal body processes, create or improve function, and/or reduce pain. These systems are either implanted or worn externally on the body. Such assistive devices range from intramuscular stimulation systems designed to limit limb atrophy in paralysis, to implanted bladder voiding systems and more complex implanted neuromuscular control.
The process of transitioning this technology into a clinically useful device will require two parallel paths of research. In the first path, experimental paradigms involving microelectrode array recordings in behaving animals will be developed in conjunction with signal processing techniques for studying the unknown aspects of neural coding and functional neurophysiology. These signal processing techniques will then be implemented in portable, low-power, wireless hardware.The second path, high-density array ECoG recordings in humans, provides a less invasive technique for neural interfaces however it still remains unknown how to extract BMI control signatures that are sufficiently spatially and temporally resolved. Neuroprosthetics is an area of intense scientific and clinical interest and rapid progress. The word’ prosthesis’ is derived from the Greek word for ‘addition’. A breakdown of the word includes ‘pros’ meaning ‘to’, and ‘thesis’, meaning ‘a placing’. Neuroprosthetic are in their infancy just now, but they offer two things that are truly wonderful:
1. Bypassing the body, and letting the mind interface directly with VR, for the ultimate immersive experience – the virtual body becomes as the normal functioning body
2. Augmented body parts will be able to be fitted to the body, and controlled by the brain as if you were born with them – after a little training, without conscious thought.

Medical bionics is the replacement or monitoring of damaged organs through engineered devices that interface with the body to improve health outcomes. In this presentation I will concentrate on medical bionic devices designed to restore or supplement function of the nervous system
lost during disease or injury.
A number of commercially available neural prostheses will be described – including the remarkably successful bionic ear and deep brain stimulation for movement control.
I will then review some of the current research performed around the world – including recent developments in brain-machine interface that will ultimately allow patients to control prosthetic limbs and wheel chairs; developments in functional electrical stimulation for gait and standing in paraplegia; and research to develop a prosthetic balance system.
Biomedical engineering students at Rose-Hulman Institute of Technology, Terre Haute, Ind., designed a robotic arm prosthetic arm for a young boy with a condition known as bilateral radial and ulnar hypoplasia, leaving him with no forearms and only two tiny fingers on each hand, according to an article on the Rose-Hulman Website.
The device was specially designed for him by senior biomedical engineering students Sara Telezyn, EJ Oruche and Clay Britton, according to the article.
The students’ project, supervised by professors Kay C Dee, Glen Livesay and Renee Rogge. The prosthetic limb works with the Michael Amerman’s fully functional fingers. The resulting device extends his reach, and allows him greater independence, while being fun and simple to operate, according to the article.
