These new cells are fitted with two pairs of stainless steel electrodes. One pair measures the current that flows through the solution under test, the second pair measures the voltage applied to the ...

The human brain is complex. Understanding deep brain function usually requires the insertion of probes that frequently result ...

Scientists have created more flexible neural electrodes that minimize tissue damage and still transmit clear brain signals. Electrodes placed in the brain record neural activity, and can help treat ...

Nanofabricated ultraflexible electrode arrays that have a cross-sectional area that is much smaller than conventional carbon fibre electrodes could be used to detect action potentials from individual ...

A new analysis probes charge transfer in porous battery electrodes for the first time. The electrochemical reactions inside the porous electrodes of batteries and fuel cells have been described by ...

Procter & Gamble has filed a patent for a pH sensing probe that includes a sensor body, a pH glass electrode, a reference electrode, and a backup pH electrode. The backup electrode can be ...

I work a lot with high voltages and others frequently replicate my projects, so I often get asked “What voltage is needed?”. That means I need to be able to measure high voltages. Here’s how I do it ...

Platinum (left) and glassy carbon (right) microelectrodes for deep brain stimulation. (Courtesy: SDSU) Deep brain stimulation (DBS) – in which electrodes implanted in the brain send electrical signals ...

Electrodes placed in the brain record neural activity, and can help treat neural diseases like Parkinson's and epilepsy. Interest is also growing in developing better brain-machine interfaces, in ...
