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.
2. Undergoing a change in optical properties with the passage of an electrical current.
Electrochromic materials can be used in window glass to provide energy efficiency in buildings, by electronically varying the level of tint in the window to control the amount of light and solar heat entering the room.
Ions are reversibly injected or removed from an electrochromic material, causing the optical density to change.
2. The phenomenon displayed by some materials of reversibly changing color when a burst of electric charge is applied.
Various types of materials and structures can be used to construct electrochromic devices, depending on the specific applications.
Electrochromism involves electroactive materials that show a reversible color change when a small DC voltage is applied.
Surgical diathermy is a method of sealing blood vessels using heat generated by a high-frequency electric current through fine needles or an electrical surgical knife.
The procedure is used during surgery to close newly cut vessels and it can also be used to stop nosebleeds and to remove vascular deformities.
2. The measurement of electrical activity produced when the cochlea is stimulated.
A needle electrode is passed through the eardrum and placed on the cochlea, the part of the inner ear concerned with hearing. The electrical activity is then recorded.3. A diagnostic test in which a probe is inserted into the cochlea in the inner ear to measure and to record electrical activity.
Certain kinds of distortions may indicate the presence of disease.
2. A measure of the total dissolved ions in a substance, which indicates the material's ability to conduct electricity.
2. The capacity of muscular tissue for contraction in response to electric stimulation.
2. Referring to a convulsive response to an electrical stimulation.
Electroconvulsive therapy is primarily used when rapid definitive response is required for either medical or psychiatric reasons; such as, for a patient who is extremely suicidal and when the risks of other treatments outweigh the risk of ECT.
There is a use for this type of treatment with specific types of mental illness; especially, if acute depression and suicidal intentions are present.
Such convulsions can sometimes treat clinical depressions which can not be treated with medication.
