Eight young women squirm under electrode-studded caps in a dark, small room in Greenwich, England.
If a chemical or biological agent binds to the electrode, it triggers a signal.
Each electrode trailed a color-coded wire, which got plugged into what looked like a backgammon board.
The ions pass through a charge-specific membrane and are adsorbed onto the surface of the electrode.

The electrons are passed via a semiconductor to an electrode, through which they leave the cell.
When spot-welding, for instance, a robot has to touch the metal with an electrode.
One main problem is that the electrode package, also called the stack, has very low energy density.
Conveyor belts carried long, wafer-thin strips of metal into printing-press-like rollers, which coated them with electrode-active material.
This layer acts as an electrode, so that the solar panel can be connected to a circuit.
It consists of a negative electrode (cathode) and a positive electrode (anode), with a vacuum between them.
Protons left behind by the oxygen migrated to a second electrode made of platinum and formed into hydrogen.

Making a deviced structure through the thin film process for semiconductors, the performance as a photo-electrode has highly improved.
The tubes then eased the passage of the liberated electrons from the cell to the electrode that collected them.
The electrons disappear into the electrode, while the protons pass through the membrane.
A123 has developed a battery that uses a doped lithium nanophosphate electrode (cathode) that eliminates combustible oxygen from the system.
Starting with a small piece of frost on an electrode, he has grown ice stars and flowery stalks of impressive beauty.
The result was that the electrode turned from oxide to metal in a way that would have pleased a medieval alchemist.
In most cases, you'll hear it tell you to remove the person's clothes and place the electrode patches in specific locations.

The whole device, together with a second electrode (known as a reference) to complete the circuit, is then mounted on a stick.
This reduced current is detected by the sensor via the gold electrode.
The electrolyte carries electrically charged particles from one electrode to the other.
Others are attached to special lipid anchors that are fixed to the gold electrode but reach all the way up through the membrane.
As well as improving sound quality for the wearer, this electrode could also make life easier for the surgeon who has to insert it.
In an ultracapacitor, positively charged ions gather on the surface of the negatively charged electrode and negative ions on the surface of the positive electrode.
Tapping into that tonic signal with an external electrode is simple.
ECONOMIST: An experiment on rats brings hope to the paralysed
Following that tradition, the brainiacs over at the University of Reading have developed a new nano-material electrode coating based on the cellular structure of plants.

At the heart of the device, however, the channels would be lined with a catalyst that reacted with the electrolyte and also acted as an electrode.
The project he whipped up, Good Times, feeds readings from the cat-eared electrode to an Arduino, which then interacts with the Call Management and M2M APIs.
On the other side the electrons return via the second electrode, having passed through the coils of an electric motor that drives the wheels of the car.
