Role of Platinum in Biomedical Applications

Introduction

Biomedical devices can be extremely advanced, technologically challenging and complex products. Using the latest manufacturing techniques and often exotic materials, biomedical devices particularly those used in humans, present some of the biggest engineering challenges for the material science and medical research communities today. By their very nature, Biomedical devices being implanted in the human body must perform exactly as they were designed, without fail from the time they are surgically implanted, until the day they expire.

The development of biomedical devices can be extremely costly requiring heavy investment across the entire supply chain focusing particularly on the design, protoyping, materials selection, manufacturing and testing of these devices.

Need of Clinical Engineers in Healthcare

During 1960’s engineers were first inspired to work in the clinical environment in response to concern about patient safety as well as rapid procreation of clinical equipment’s. In the process, a new engineering discipline evolved i.e “Biomedical or Clinical Engineering”.

In the not-too-distant past, a developing nation aim to be seen as a country that is deficient in access to modern technology but today, increasing globalization can help make a new technology serviceable wherever that it might be useful.

Headset creates Soundscape for Rehab of Blind

Photos of EyeMusic in action
A new headset in development for visually impaired people plays sounds to tell wearers about the size, shape and color of objects in front of them. For example, the device might help people choose a red apple out of a plate of green ones.

A new headset, still in its prototype stage, tells visually impaired people what’s in front of them by playing different sounds for different objects. Eventually the headset, called EyeMusic, may be able to help visually impaired people with such everyday tasks as choosing produce at the supermarket, according to EyeMusic’s creators.

New Robotic Legs to mimic exact Human Style of walking

Washington: Scientists claim to have invented the world’s most advanced pair of robotic legs that accurately mimic human walking, a feat they say has brought the goal of developing human-friendly household robots a step closer.

Created by a team from the Department of Electrical and Computer Engineering at the University of Arizona, the legs are the first to mimic walking in a biologically accurate and energy-efficient manner.

The biological accuracy of this robot, which has been detailed in the Journal of Neural Engineering, has allowed the researchers to investigate the processes underlying walking in humans and may bolster theories of how babies learn to walk.
It could also help understand how patients with spinal cord injury can recover the ability to walk, the team said.

Random LASERS for Speckle free Biomedical Imaging

Random lasers may have a future in imaging. A team at Yale University (New Haven, CT) who last year made random lasers with low spatial coherence has now used those low-coherence lasers for speckle-free imaging. The demonstration could open the door to new laser applications in biological imaging, picoprojectors, and cinema projectors.

A byproduct of coherence, laser speckle is a shifting pattern of bright and dark zones produced when a laser beam passes through a scattering medium. It’s tolerable in many laser applications, but speckle degrades images recorded in laser light or displayed by laser projectors.
