Ekso Bionics Unveils EksoNR Neurorehabilitation Suit

Ekso Bionics, the California company that makes some of the most advanced exoskeletons out there, is releasing its latest neurorehabilitation suit, the EksoNR. Designed primarily to help people recovering from a stroke, the device recreates the natural movement of the legs and helps patients re-learn how to walk, sit, and do all the things they [&h (Read more...)

Voltron Technology Lights Up Brain Activity in Real Time

While scientists have a variety of tools on hand to monitor and manipulate living brains, they still lack the ability to observe how large numbers of individual neurons operate in real time. Now, researchers at the Howard Hughes Medical Institute have developed a remarkable technology, published in the journal Science, that illuminates neurons just (Read more...)

Neurons Grow on Crosslinks of Carbon Nanotubes

Carbon nanotubes have a host of interesting properties. They are biocompatible and electrically conductive, so have been investigated as a possible material for growing nerve tissues. To make carbon nanotubes cooperate as desired, novel forms are required and researchers at SISSA (International School for Advanced Studies) and University of Trieste (Read more...)

CAVA Device Spots Nystagmus to Diagnose Dizziness

Dizziness is a common condition but its underlying causes can be very difficult to diagnose. It is usually unpredictable and doesn’t last very long, so by the time a patient presents to the physician everything checks out as normal. Detecting nystagmus (uncontrolled eye movements) is a pretty reliable way of diagnosing peripheral vestibular d (Read more...)

Wireless Brain Implant Controls Mice Using Drugs and Light

Optogenetics is a quickly evolving field that allows scientists to activate specific neurons using bursts of light. The technique may help to uncover the basis of neurological diseases and how to tame them. Using optogenetics to assess how different drugs affect the central nervous system may offer a powerful new scientific tool. To that end, [&hel (Read more...)

Imperceptible Wearable Electronics Only Microns Thin

When we think of wearable electronics, devices such as smartwatches, chest-strap heart monitors, and wrist-worn activity trackers come to mind. In the future, and one that is seemingly not that far away, wearables may look like tattoos that are only microns thick. That may be thanks to researchers from the University of Houston, University of [&hel (Read more...)

Implanted Electrodes Improve Powered Prosthetic Arms

Today’s conventional powered prosthetic arms usually have a few built-in electrodes that make contact with patient skin. These are good enough to open and close a simple claw, but for more nuanced control of prostheses with multiple degrees of freedom and individual fingers, a better approach is required. Implantable electrodes can gather a g (Read more...)

Smart Contact Lens Zooms On Demand

Though bifocal and progressive contact lenses are now widely available, they’re still “dumb” devices that require the user to adjust to them. Researchers at the University of California San Diego and the Harbin Institute of Technology in China have now developed a biomimetic soft contact lens that can be made to zoom in and out [& (Read more...)

Generating Hallucinations Using Optogenetics

About a decade ago, Karl Deisseroth of Stanford University developed a technology called optogenetics. It allows scientists to stimulate individual nerve cells using light beams within the brains of live and moving animals. Now, this technology has been used to generate visual hallucinations within lab mice, causing them to act as though the things (Read more...)

New Nanoparticles Help Spinal Cords to Heal Following Injury

When people damage their spinal cords, a lot of the long-term consequences often stem from the body’s overreaction to the injury. That’s because the blood-brain barrier protecting the spinal cord becomes compromised and overly aggressive immune cells flood in. Now, a team from the University of Michigan has developed a way of using intr (Read more...)

Super Sensitive Electronic Skin for Prosthetic Devices

Artificial skin with the ability to feel is a major research goal for engineers working on improving prosthetic technology. Researchers in the past have created materials with sensors spread over a few square inches, but these have typically had a number of limitations. One thing that causes many such electronic skins to be impractical is [… (Read more...)
