An
electrode is a conducting material that is used to make electrical contact with non-metallic parts of a circuit. It helps to carry electric current between two points and is commonly used in batteries, electrical wiring, and medical devices.

Then, while the participants performed an attention testing task, neural activity in the brain was measured by making use
of electrodes on the scalp.
It is done by placing
electrodes in the brain to pick up specific patterns of electrical activity that relate to thoughts about moving.

using electrodes for high - frequency stimulation at various places on their spinal cords to induce coughing.
He suggested that humanity could either plug
electrodes into our brains and upload them to computers, or have a deeper relationship with existing technology.
Study participants were hooked up to
electrodes for these conversations, during which they were asked questions about their relationship while sitting next to their spouses.
«Compared to the transition - metal - containing
electrodes materials in conventional lithium - ion batteries, organic materials are abundant, inexpensive, and environmentally friendly,» he says.
It is done using
electrodes placed in the brain, which recognise specific patterns of electric activity that occur when a person thinks about moving.
One virtual - reality experiment they are planning will record
from electrodes in rats running on a stationary ball surrounded by screens showing changing environments.
The technique measures the resistance to a small current generated
by electrodes on the scalp to gauge electrical activity in the brain.
The system consists of
electrodes attached by leads to a generator which can communicate with a computer.
The capsules are suspended
between electrodes switched on and off by an electronic circuit, and each one can be controlled individually.
A leading contender is the lithium - metal battery, which differs from lithium ion technology in that it contains lithium
metal electrodes.
Tools available to study these reactions can only provide information on the average composition of
electrodes at any given point in time.
With the answers from this study, scientists can manufacture identical particles that are then assembled into
battery electrodes.
It may also work for
electrodes made of other metals, such as magnesium, calcium or aluminum, that also have potential for storing much more energy than today's batteries.
As the name implies, the technique involves electrical currents flowing
through electrodes in random pulses, activating neurons in multiple brain areas.
To compare these patterns to the actual electrical activity in the brains, the researchers
inserted electrodes capable of recording the firing patterns of individual neurons.
Once it's clinically proven, however, neural dust will just replace
wire electrodes.
When the field reached a certain strength, the mixture suddenly separated into two phases, with the silicone - rich phase lining the edges of the
tiny electrodes.
He then places thin, dense grids of sensitive
electrodes directly onto the brain's exposed surface; these sensors read changes in the activation behavior of columns of neurons beneath them.
On the bottom, the sticker is equipped with two
electrodes which are connected to a charging port of a device.
A: We could
put electrodes in the speech area of the brain and ask a patient to think of different words and observe how the cells fire in different ways.
The finding has already led to a better understanding of how to deploy deep -
brain electrodes.
Also, not much happened
when electrodes in a neighboring region were stimulated.
The team plans to use the same high frequency recordings from
smaller electrodes to answer this question.
The company says its new model has extra
electrodes designed to prevent interference for better and more accurate heart rate capture.
Then pulses of electric current are passed through her brain
via electrodes positioned on her head.
The results, he said, can be directly applied to many oxide and
graphite electrodes used in today's commercial lithium ion batteries and in about half of those under development.
The metal - molecule interfaces are indicated; the golden balls represent
gold electrodes.
The results of this work could lead to the ability to design materials that have extensive surface areas that can be used in batteries as high durability
silicon electrodes.
Materials like this can be used for fuel
cell electrodes, with far lower costs than the current ones.
This method consists of applying low voltage electric currents on the patient's head by means of
electrodes during short periods of time.
The same technology is perfectly suited to keeping heart
monitor electrodes moist all the time.
That's true in part because designing a battery to discharge quickly requires using very
thin electrodes stacked in many layers.
By comparing performance of cells on paper with those fabricated on glass and plastic films with
different electrodes, we identify avenues that can help guide future research for improved performance.
This concept involves the replacement of
solid electrodes with energy - dense liquids.
For this purpose, work - function engineering of both graphene and reduced graphene
oxide electrodes was carried out.
Because
thicker electrodes can store more charges, they allow a battery to hold more energy.
The motors were mounted outside the skull, and
electrodes passed through plugs in the scalp.
This removes the need for
traditional electrodes, reduces the structure's bulk and allows more choices in the type and thickness of plates.
The CO2 will eventually disappear as the heat and direct currents from steel and
nickel electrodes are infused into it.
How about a big plastic tank of seawater and a couple of stainless
steel electrodes?
A transparent matrix of
electrodes above and below the capsules is manipulated to draw one or the other pigments to the surface.
Now, researchers have found this turbulence likely emerges from heat - induced sound waves generated at the
plasma electrodes.
