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.

electroacoustic transducer (s) (noun); electroacoustic transducers (pl)
A device that produces energy waves from electricity to sound or from sound to electricity: Examples of electroacoustic transducers include such devices as microphones, earphones, and loudspeakers.
electroacoustics (s) (noun) (a plural form that functions as a singular)
The science which deals with sound and its relationship to electricity: "Loudspeakers and microphones are examples of the applications of electroacoustics."

"Electroacoustics is also used in sound broadcasting, sound recording and reproduction; as well as, ultrasonic flaw detection and technology."

electroacupuncture (s) (noun) electroacupunctures (pl)
1. A form of piercing using low frequency electrically stimulated needles to produce a painless procedure in order to treat certain ailments.
2. A procedure for relief of pain or spasticity consisting of electrical stimulation through an electrode needle, which usually is inserted into the vicinity of a nerve.
electroacupuncture after Voll , EAV
A system of diagnosis and treatment based on the measurement of the electrical characteristics of acupoints (specific sites for needle insertions), the results being used to determine a specific remedy based on the diagnosed research.

The term was named for Dr. Reinhold Voll, who in 1939, started to apply electroacupuncture in his medical practice and in 1953, together with engineer F. Verner, started to develop his special method of electroacupuncture.

Electroacupuncture, also known as electroacupuncture according to Voll (EAV), electrodermal screening (EDS), bioelectric functions diagnosis (BFD), bio resonance therapy (BRT), or bio-energy regulatory technique (BER), is a controversial alternative medicine method of using electrodiagnostic devices to diagnose and to treat "energy imbalance" often using homeopathic products, first used by Reinhold Voll by combining acupuncture with galvanometer (detects, measures, and determines the direction of a small electric current) in 1958.

electroaffinity
The force by which ions hold their electric charges.

Ions are atoms or a group of atoms that have acquired a net electric charge by gaining or losing one or more electrons.

Ions in the organism are universal participants in the bodily metabolism.

In particular, ions participate in the mechanisms responsible for the permeability of biological membranes, in the regulation of muscular contraction, and in the propagation of the excitation impulses within the nerve tissues.

electroalloy
A nonmagnetic alloy frequently used in a radio chassis.
electroanalgesia
1. Analgesia induced by using an electric current or the use of an electric current to relieve pain.
2. Relief from pain by the application of low-intensity electric currents locally or through implanted electrodes.

It may involve stimulation of brain or spinal cord structures through indwelling electrodes, or stimulation of a peripheral nerve.

electroanalysis (s), electroanalyses (pl)
1. The use of electrolysis (process of splitting water into its components) to perform chemical analysis.
2. Chemical analysis using electrolytic techniques.
electroanalytic chemistry
A branch of chemistry concerned with the analysis of compounds by the use of electrical properties to produce characteristic observable changes in the substance being studied.
electroanesthesia, electrical anesthesia (s) (noun); electroanaesthesias, electrical anaesthesias (pl)
A general elimination of pain produced by an apparatus that passes electricity of a certain frequency, amplitude, and a wave density through the brain: Dr. Anderson used electroanesthesia while he was removing warts from Lina's feet.
electroappendectomy
An appendectomy using an electric cautery or similar device.

A cautery is an instrument or substance used to seal a wound or to destroy damaged or infected tissue by burning.

electroaugmentation
A electrical pacing of the heart.
electroaxonography, axonography
The recording of electrical changes in axons (an extension of a neuron cell body that transports information away from the cell body, usually by an electrical impulse).

A neuron or neurone is an excitable cell specialized for the transmission of electrical signals over long distances.

electroballistics, electro-ballistilcs
1. The measurement of the speed of military projectiles with electronic equipment.
2. The art or science of measuring the force or velocity of projectiles by using electricity.
electrobasograph
1. An apparatus for measuring the weight bearing period of limbs during walking.
2. A device for recording a person's gait or manner of walking.
