(Nanowerk Spotlight) Detecting specific chemicals in complex mixtures remains a persistent scientific challenge. When multiple compounds exist together – as in cosmetics, pharmaceuticals, or ...

To make electric vehicles more practical and attractive to consumers, lithium-ion batteries need some improvements. Mainly, they need to hold much more energy per weight to allow vehicles to go longer ...

Microneedle electrodes can penetrate beneath the skin, allowing for more accurate bioelectrical signal acquisition (such as EEG, ECG, and EMG) from outside the body. Research into their materials has ...

Flexible thin-film electrodes placed directly on brain tissue show promise for the diagnosis and treatment of epilepsy. Thanks to an innovative yet straightforward design, these durable electrodes ...

Current electrochemical theory does not adequately describe realistic platinum electrodes. Scientists at Leiden University have now, for the first time, mapped the influence of imperfect platinum ...

The future of electroencephalography (EEG) monitoring may soon look like a strand of hair. In place of the traditional metal electrodes, a web of wires and sticky adhesives, a team of researchers from ...

Researchers based in Australia and India recently published a study with their findings on developing improved electrodes for wearable heart monitors. The scientists researched options for developing ...

Researchers have created heart monitoring sensors that conform to the skin, are comfortable, and can be worn while people are ...

Austrian scientists have developed wafer-thin tattoo electrodes that can record brain activity. These "tattoos" are dry electrodes, and unlike typical ones, they don't require a gel medium to function ...

It’s an unusual aesthetic, but it works: Spray-on tattoos that dot the head can collect brain activity without the consternation caused by typical tests. The electronic tattoos, described December 2 ...
