Printing microelectrode array sensors on gummi candy

Microelectrodes can be used for direct measurement of electrical signals in the brain or heart. These applications require soft materials, however. With existing methods, attaching electrodes to such materials poses significant ...

Researchers use voltammetry to probe the brain's chemistry

(Phys.org)—Our brains are constantly awash in chemicals that serve as messengers, transporting signals from one neuron to another.  It's a really nifty system, although scientists still aren't clear on how, exactly, those ...

Electrode

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte or a vacuum). The word was coined by the scientist Michael Faraday from the Greek words elektron (meaning amber, from which the word electricity is derived) and hodos, a way.
