MEMS-based systems can significantly improve accuracy in aligning hip and knee implants with a patient’s anatomy, reducing discomfort and the need for revision surgery.

Navigation is typically associated with cars, trucks, aircraft, ships, and, of course, people. It has also begun to play a significant role in medical technology, where it is used in precision surgical instruments and robotics. The design requirements of a surgical navigation tool share broad similarities with traditional vehicle navigation, but they also pose some distinct challenges—because the devices are used indoors, GPS assistance is not possible, for example—and they require a higher level of performance.
In this article, we will examine the unique challenges of medical navigation applications and explore possible solutions ranging from sensor mechanisms to system characteristics. Critical sensor specifications will be reviewed as well as potential error and drift mechanisms that should be taken into account during sensor selection. Enhancing sensors through integration, fusion and processing, by the use of Kalman filtering, for example, also will be highlighted. Before diving into the details, however, it may be useful to review some fundamental principles of inertial microelectromechanical systems (MEMS) sensor technology.

Researchers at Cornell’s College of Veterinary Medicine may have solved a problem that has long vexed neurologists, including those involved in treating and studying HIV/AIDS-related neurological problems. According to a new report published in the September 14 issue of The Journal of Neuroscience, the Cornell team has found a way to open and close the blood-brain barrier, which may allow for more effective treatment of a variety of brain-centered diseases and complications, such as those associated with HIV/AIDS.

Two unconnected things occurred simultaneously – one was the mixed feelings to diversify my writings and other was invitation by Kush Tripathi to write for his Biomedikal blog. I promised myself to complete both but as I started, the lazy part of mine promptly suggested me to mix the two and present a single dish (whose taste you readers have to rate at the end of the article). Kush Tripathi, my pen friend, (in today’s term a Facebook or a Twitter friend), a post-graduate student in biomedical pinged me one fine evening and insisted to pen down my opinions on biomedical engineering. I thought the task would be quite easy as I am a post graduate in the same field with lots of personal desire to study the subject, but Kush added a trouble and challenged me to give the article an informal touch – a personal touch rather than a technical write-up which is commonly available on a Google search. At that time I almost overlooked his expectations but as I started to cook the dish I realized its importance. Any article when written with personal experience adds readers.

New measurement technologies and techniques provide researchers more complete look at neurological activity
In 1991, Carl Lewis was both the fastest man on earth and a profound long jumper, perhaps the greatest track-and-field star of all time in the prime of his career. On June 14th of that year, however, Carl Lewis was human. Leroy Burrell blazed through the 100-meters, besting him by a razor-thin margin of three-hundredths of a second. In the time it takes the shutter to capture a single frame of video, Lewis’s three-year-old world record was gone.

Warren Grill was given a challenge in 2002. His soon-to-be business partner, Geoff Thrope, asked the Duke University Addy Professor of Biomedical Engineering: “You know, Warren, you’re doing a great job of being an academic biomedical engineer and publishing papers that end up in journals on a shelf. But is that sufficient?”
Since then, Grill (ENG’89) has risen to the challenge, translating fundamental research to several technologies with significant clinical impact. He and Thrope cofounded medical device start-up NDI Medical, LLC, a technology incubator that partners with academic researchers and supports in-house scientists and engineers in developing high-growth companies focused on innovative neurostimulation technologies. In recognition of his many innovations, Grill was named Neurotech Business ReportNeurotechnology Researcher of the Year in 2003, and in 2007 received the College of Engineering Distinguished Alumni Award for Service to the Profession.
