electro-, electr-, electri-

(Greek > Latin: electric, electricity; from amber, resembling amber, generated from amber which when rubbed vigorously [as by friction], produced the effect of static electricity)

Electronics in our lives consists of numerous tools

Equipment which we use everyday relies on electronics to function including calculators, car controls, cameras, washing machines, medical scanners, mobile telephones, radar systems, computers; as well as many other applications or devices which are listed in this unit.

1. To form with the electrodeposition of metal in finished or semifinished form, as sheets or tubes or electrotypes.
2. To produce (shaped objects) with the electrolytic deposition of metal on a mold.
1. Forming or shaping components by electrodeposition of the metal on a pattern or mold.
2. Producing or reproducing (an object) with electrodeposition on a mold.
3. A procedure that produces, or reproduces, objects made of metal with a technique that is essentially precision electroplating.

The metal is deposited onto a mandrel or a former of what is the preferred shape to a desired thickness, followed by the removal of the mandrel to produce a free standing metal object.

This process is often used to produce precise optical elements, and solid-state electronic devices (integrated circuit boards, computer chips); as well as, the production of flat or perforated metal sheets, seamless perforated metal tubes, and metal bellows.

Almost any metal or alloy which can be electroplated can also be used for electroforming.

electroforming process
An electrochemical process of metal fabrication using an electrolyte, an anode to supply the metal, and a control of the electrical current and of the deposit of metal on the matrix of a reflector.
To galvanize steel or iron articles by placing them in a solution in which zinc or zinc salts are dissolved.

With the aid of electricity, the zinc is transferred onto the articles.

A reference to electrogasdynamics or the flow of high-pressure combustion gas to generate electricity.
electrogasdynamic spray gun
A portable electrostatic spray gun in which a convective discharge or electric wind is used to charge particles of paint negatively in an electrogasdynamic channel.

Guiding streams of air keep the charged paint particles in a narrow beam which keeps over spraying to a minimum.

1. Use of the flow of high-pressure combustion gas to generate electricity; especially, in high-voltage electric-power generation, air-pollution control, and paint spraying. 2. The conversion of heat energy into electricity by sweeping charged particles through an electric field in a stream of gas.

Electrogasdynamics is a procedure for generating electricity. Small particles of dust, smoke, fog, etc are charged in a low-voltage region and then transported by a gas stream to a high-voltage region, where the charges are removed.

Work is done on the particles in moving them against the electric field and electricity is generated.

The creation of a communication between the stomach and the small intestine, utilizing an electric cautery (an instrument which is used to coagulate or to destroy tissue by means of heat).
1. A study in which the electrical current generated by the muscles of the stomach are sensed and recorded.
2. A test in which the electrical current generated by the muscles of the stomach are sensed and recorded in a manner very similar to that of an electrocardiogram of the heart.

An electrogastrogram is performed by taping electrodes to the skin on the upper abdomen over the stomach.

Recordings from the muscles are stored and analyzed by a computer and the electrogastrogram is performed in order to diagnose motility disorders of the stomach, conditions which prevent the muscles of the stomach from working normally.

1. An instrument for recording the electrical activity of the stomach by means of swallowed gastric electrodes.
2. A graphic recording of the change in electrical potential associated with gastric secretion and movement.
1. The recording of the electrical activity of the stomach as measured between its lumen (cavity) and the body surface.
2. The process of recording and analyzing the electrical activity of the stomach.
1. The production of electricity by a living plant or animal.
2. The creation of electricity; especially, by living organisms.
A reference to the creation of electricity; especially, by living organisms.
1. The production of electrical impulses in living organisms or tissues.
2. Referring to a physiological process that generates a significant current which directly contributes to a cell membrane potential or an electric potential (possible electric tension or pressure) that exists on two sides of a membrane or across the wall of a cell.
3. Descriptive of a substance that contributes to an electrical potential across a membrane. 4. A reference to a procedure; such as, the pumping of ions across a membrane, in which a net charge is transferred, so that an electrical field is set up unless the charge can be dissipated by another process.
In astronomy, a strong emission of ultraviolet light occurring on the sunlit side of various planets; especially, Uranus.
