On this episode of The Pulse, rewired nerves from amputated limbs allow for prosthetic control with existing muscles, a bioengineered blood vessel is transplanted, diabetes is diagnosed through breath analysis alone, and a new technology is paving the way for low-cost electronic devices that work in direct contact with living tissue inside the body.
Diastolic heart failure is responsible for more than half of all cardiac failure. The condition...
Graduate students developed a new textile microfluidic platform using hydrophilic threads...
Professor Il-Doo Kim of Materials Science & Engineering, KAIST, developed an exhaled breath sensor that is composed of highly porous tin dioxide (SnO2) nanofibers with a unique nanostructure functionalized by catalytic platinum (Pt) particles. This unique structure reacts to acetone gas, which is known as a biomarker of diabetes, for the fast diagnosis of the disease within 10 seconds.
Researchers at Case Western Reserve University used a flat interface nerve electrode (FINE) to demonstrate direct sensory feedback. By interfacing with residual nerves in the patient's partial limb, some sense of touch by the fingers is restored. Other existing prosthetic limb control systems rely solely on visual feedback.
A team of researchers at the Rehabilitation Institute of Chicago (RIC) demonstrated a type of peripheral interface called targeted muscle re-innervation (TMR). By rewiring nerves from amputated limbs, new interfaces allow for prosthetic control with existing muscles. Former Army Staff Sgt. Glen Lehman, injured in Iraq, recently demonstrated improved TMR technology.
In this video, a representative at Nephosity demonstrates MobileCT, an app for mobile collaborative teleradiology. It allows for a user (such as a doctor or patient) to use their mobile devices to view x-rays, MRIs, etc., and to collaborate with other users (such as other doctors or relatives).
Professor Brian T. Cunningham and his graduate students demonstrate their development of using a smartphone camera as a high resolution spectrophotometer. Cunningham’s group is now collaborating with other groups across campus at the U. of I. to explore applications for the iPhone biosensor.
The tail of a seahorse can be compressed to about half its size before permanent damage occurs, engineers at the University of California, San Diego, have found. The tail’s exceptional flexibility is due to its structure, made up of bony, armored plates, which slide past each other.
Panasonic, together with the Belgium-based research institution IMEC, has developed a DNA testing chip that automates all stages of obtaining genetic information, including preprocessing. This development is expected to enable personalized, tailor-made therapy to become widespread.
Amputees are enjoying an improved quality of life with wireless enabled prostheses. The prosthetic sends data to the care-giver to make better informed adjustments, and the patient can even make adjustments from their mobile phone.
A unique pair of eyeglasses developed by a Florida International Univ. student team could revolutionize the lives of the blind, enabling them to walk into a library or a store, pick up any book or a can of soup and read it. The Eyetalk concept has been hailed by venture investors as a potentially breakthrough product that could make a difference for disabled people worldwide.
A new spinal implant developed in Israel, has radically improved the life of at least one patient who, four years ago, believed he would spend his twilight years in constant pain. Seventy-nine-year-old Moshav farmer Yehuda Schwartz suffered from a debilitating back condition common among senior citizens but says, since receiving the implant, he's been given a new lease on life.
To study the effects of improvised explosive devices on soldiers and help provide continuing treatment, Georgia Tech Research Institute (GTRI) researchers have developed IBESS, a sensor system that measures the physical environment of an explosion and collects data that can correlate what the soldier experienced with long-term outcomes.
The University of Connecticut and Pratt & Whitney have created one of the most advanced additive manufacturing laboratories in the country. The new Pratt & Whitney Additive Manufacturing Innovation Center at UConn is the first additive manufacturing facility in the Northeast to work with metals rather than plastics.
As demonstrated in these videos, sitting at rest, the adaptive and multifunctional material is smooth, clear and flat; droplets of water or oil on its omniphobic surface flow freely down its surface. Stretching or bending it makes the fluid surface rougher. The rough surface is opaque, and also confers the ability to precisely control the movement of water or oil droplets.
For the first time scientists have printed human embryonic stem cells using a 3D printer. The Heriot-Watt University team's research could eventually lead to human organs being printed on demand and an end to animal drug testing. Jim Drury reports.
In this installment of Design Tips for Plastic Injection Molding, Kevin Crystal talks about designing living hinges in plastic parts. Using the Protomold Design Cube, Kevin demonstrates the best resins to use when designing living hinges.
