Wearable Nanowire Sensors Monitor Electrophysiological Signals

Researchers from North Carolina State University have developed a new, wearable sensor that uses silver nanowires to monitor electrophysiological signals, such as electrocardiography (EKG) or electromyography (EMG). The new sensor is as accurate as the “wet electrode” sensors used in hospitals, but can be used for long-term monitoring and when a patient is moving.

Piezo Motors Power MRI Robot

Surgeons treating brain cancer face a conundrum: They can capture ultra-high-resolution images of the tumor using magnetic resonance imaging (MRI) or they can use ultra-precise surgical tools to remove the tumor, but they can’t do both at the same time. At least they couldn’t prior to the creation of the innovative MRI robot from the Worchester Polytechnic Institute team.

Robotic Walker Helps Patients Regain Natural Gait

Researchers from the National University of Singapore have invented a novel robotic walker that helps patients carry out physical therapy sessions to regain their leg movements and natural gait. The system also increases productivity of physiotherapists, and improves the quality of rehabilitation sessions. The walker can support a patient’s weight while providing the right amount of force at the pelvis to help the patient walk with a natural gait.

Imaging Via Nanoparticles Could Monitor Cancer and Other Diseases

MIT chemists have developed new nanoparticles that can simultaneously perform magnetic resonance imaging (MRI) and fluorescent imaging in living animals. Such particles could help scientists to track specific molecules produced in the body, monitor a tumor’s environment, or determine whether drugs have successfully reached their targets. The researchers have demonstrated the use of the particles, which carry distinct sensors for fluorescence and MRI, to track vitamin C in mice. Wherever there is a high concentration of vitamin C, the particles show a strong fluorescent signal but little MRI contrast. If there is not much vitamin C, a stronger MRI signal is visible but fluorescence is very weak. The researchers are now working to enhance the signal differences that they get when the sensor encounters a target molecule such as vitamin C. They have also created nanoparticles carrying the fluorescent agent plus up to three different drugs. This allows them to track whether the nanoparticles are delivered to their targeted locations. These particles could also be used to evaluate the level of oxygen radicals in a patient’s tumor, which can reveal valuable information about how aggressive the tumor is. Source:

VINCENT Systems Prosthetics Give Patients A New Feel For Life

The human hand is a biomechanical marvel, but our hands are easy to take for granted because we depend on them all day long. People without all or part of their hands, however, know full well the value of what is missing as they struggle to perform even simple, everyday tasks.
