Elon Musk’s Neuralink, the secretive company developing brain-machine interfaces, showed off some of the technology it has been developing to the public for the first time. The goal is to eventually begin implanting devices in paralyzed humans, allowing them to control phones or computers.

The first big advance is flexible “threads,” which are less likely to damage the brain than the materials currently used in brain-machine interfaces. These threads also create the possibility of transferring a higher volume of data, according to a white paper credited to “Elon Musk & Neuralink.” The abstract notes that the system could include “as many as 3,072 electrodes per array distributed across 96 threads.”

Computer system transcribes words users “speak silently”

IMG_6356

MIT researchers have developed a computer interface that can transcribe words that the user verbalizes internally but does not actually speak aloud.

The system consists of a wearable device and an associated computing system. Electrodes in the device pick up neuromuscular signals in the jaw and face that are triggered by internal verbalizations — saying words “in your head” — but are undetectable to the human eye. The signals are fed to a machine-learning system that has been trained to correlate particular signals with particular words.

Amprius raises $30 million to develop high-energy silicon batteries

The startup, Amprius is working on a new type of long-lasting lithium-ion batteries for laptops and electric vehicles. The company has started to sell its batteries for use in portable electronics. Amprius recently raised $30 million in venture capital to develop its next-generation batteries, which use high-energy silicon electrodes. The company says the batteries will store about 50 percent more energy than the battery cells in today’s electric vehicles.

Scientists create electrode that lets you taste virtual food on your tongue

The same research team is also working on a digital lollipop.

In Sword Art Online, an anime series, gamers take part in a virtual world that is teeming with danger, but also with food. What if such an experience was a reality? What if you could not only interact with food in a virtual environment, but also actually taste it? Scientists at the National University of Singapore have developed a new electrode that could be the first step in making that happen. (Video)

Researchers develop ‘smart paint’ that monitors structural damage

smart-paint-1

Dr Mohamed Saafi and David McGahon have developed a smart paint that can detect microscopic faults in large structures.

Researchers have developed a ‘smart paint’ able to detect tiny faults before damage can occur, and at a fraction of the cost of current methods.

Cheaper And More Reliable Lithium-Ion Batteries

Cheaper And More Reliable Lithium-Ion Batteries

Lithium-ion cells that use polymer electrolytes can be affordably packaged in compact, flexible pouches  

A new incarnation of lithium-ion batteries based on solid polymers is in the works. Berkeley, CA-based startup Seeo, Inc. says its lithium-ion cells will be safer, longer-lasting, lighter, and cheaper than current batteries. Seeo’s batteries use thin films of polymer as the electrolyte and high-energy-density, light-weight electrodes. Lawrence Berkeley National Laboratory is now making and testing cells designed by the University of California, Berkeley spinoff.

Electrical Stimulation Through The Spinal Cord May Ease Parkinson’s Symptoms

Electrical Stimulation Through The Spinal Cord May Ease Parkinson’s Symptoms

Neural activity in the brain of a Parkinsonian rat before (top) and after (bottom) electrical stimulation is applied to its spinal cord.  

Delivering electrical stimulation to the spinal cord through tiny, platinum electrodes could ease the severe motor deficits of Parkinson’s disease as effectively as a much more intrusive procedure currently in clinical use, according to a new study in rodents. If the findings are confirmed in humans, scientists say, the procedure could dramatically improve treatment for the disease by making electrical therapies safer and more broadly available.

Platinum-Free Fuel Cells Eliminates Need For Expensive Catalysts

Platinum-Free Fuel Cells Eliminates Need For Expensive Catalysts 

 A new polymer, shown in powdered form, can be used to make stable fuel-cell membranes that conduct negatively charged ions.

Fuel cells are, in principle, the most efficient way to convert hydrogen fuel into electricity. But they require expensive catalysts such as platinum to split hydrogen into ions and electrical current. Cheaper metals simply can’t withstand the harsh acidic environment of the fuel cell. Now researchers in China have developed a fuel cell that uses a new membrane material to operate in alkaline conditions, eliminating the need for an expensive catalyst. The power output of the new prototype, which uses nickel as a catalyst, is still relatively low, but it provides a first demonstration of a potentially much less expensive fuel cell.

Internal External Defibrillator Offers Safer Way To Jump Start Ailing Heart

Internal External Defibrillator Offers Safer Way To Jump Start Ailing Heart 

 A new implantable defibrillator uses electrodes that don’t have to be inserted into the heart.

Six people in New Zealand have become the first to be implanted with a novel form of cardiac defibrillator that could radically change the way that people with life-threatening heart conditions are treated.

Infrared Light Could Bring Music To The Deaf

Infrared Light From Xbox

Scientists have accidentally discovered that infrared light can stimulate neurons in the inner ear like sound waves do. While trying to “weld” nerves with heat from a laser, surgeons found that the light could stimulate the ear nerves extremely precisely. A research team led by Claus-Peter Richter at Northwestern University in Chicago decided to explore this idea further.
