Device Designed to Avert Repeated Breast Cancer Surgeries

June 27, 2013 12:15 pm | by Johns Hopkins | Comments

When a breast tumor is detected, many women opt to have a lumpectomy, which is surgery designed to remove the diseased tissue while preserving the breast. But during this procedure, doctors cannot learn right away whether all of the cancerous tissue has been removed, with no microscopic signs that cancer cells were left behind.

Nerve Interface for Direct Sensory Feedback

June 20, 2013 12:20 pm | by DARPA | Comments

Researchers used a flat interface nerve electrode 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. Unlike visual feedback, direct sensory feedback allows patients to move a hand without keeping their eyes on it—enabling simple tasks, like rummaging through a bag for small items, not possible with today's prosthetics.

Researchers Come to Grips with Seahorse Armor

June 20, 2013 9:21 am | by Reuters | Comments

Researchers are developing a new type of gripping arm for medical and engineering applications, using the the flexible armor of seahorses as a model. A team at the University of California San Diego says the creature's natural armor plating provides a degree of strength and flexibility that does not exist outside nature. Tara Cleary reports.

The Pulse: New Interface Rewires Nerves from Amputated Limbs

June 13, 2013 9:43 am | by Eric Sorensen, Coordinator of Multimedia Development | Comments

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.

Exhaled Breath Sensor for Diagnosis of Diabetes Using Platinum-Loaded SnO2 Nanofibers

June 12, 2013 10:48 am | by The Korea Advanced Institute of Science and Technology | Comments

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.

Nerve Interface for Direct Sensory Feedback

June 12, 2013 10:33 am | by DARPA | Comments

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.

Targeted Muscle Re-innveration for Advanced Prosthetic Control

June 12, 2013 10:26 am | by DARPA | Comments

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.

Robotic Design Inspired by Seahorses

May 2, 2013 2:08 pm | by University of California - San Diego | Comments

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.
