Researchers successfully controlled a cursor using only brain signals from six neurons, enabling real-time and complex goal-directed behavior. This technology may one day restore interaction with the environment for paralyzed individuals.
Researchers at the University of North Carolina at Chapel Hill have discovered that carbon nanotubes can store more energy than conventional graphite electrodes, potentially leading to longer-lasting batteries. The study found that carbon nanotubes can contain roughly twice the energy density of graphite.
Researchers from Bell Labs have created molecular-scale organic transistors that can rival silicon transistors in performance. The breakthrough could lead to thousands of times more transistors being squeezed into the same space as today's circuits.
Scientists at Max-Planck-Gesellschaft developed a simple electrochemical procedure to fabricate three-dimensional microstructures. The innovation lies in applying ultrashort voltage pulses between the electrodes, which confines the electrochemical reaction to a small region and enables precise micromachining.
Researchers at UMass have made a major step forward in nanoscopic pattern transfer, creating precise designs on polymer films without the use of chemicals. The breakthrough has implications for producing smaller integrated circuits, magnetic storage, and on-chip sensors.
Researchers from the University of Delaware have developed a cheap and disposable biosensor using gold-on-plastic technology, which can detect targeted molecules in bodily fluids with high accuracy. The device is more specific than existing methods, such as latex agglutination tests, and can be produced at a lower cost.
Researchers at Case Western Reserve University are developing a new neural prosthesis technology that uses microstimulation to directly stimulate the spinal cord. This approach aims to improve the health and independence of individuals with quadriplegia and paraplegia, who currently lack control over vital functions.
Researchers at Stanford University have invented a quantum electron pump, a device that operates according to the laws of quantum physics. The pump uses slight changes in shape created by electrostatic forces to push electrons through it, allowing for the movement of electrons without relying on voltage differences.
Researchers at UNC Chapel Hill have developed a novel solid-state metal sensor that can accurately measure the acidity of chemical solutions, including body fluids. The electrode may help predict cardiac muscle ischemia and offer advance warning for potential heart attacks.
Researchers have developed a neurotrophic electrode that can be implanted in the brain to help paralyzed patients communicate through a computer. The system uses neural signals to drive a cursor on a screen, allowing patients to interact with their environment.
