	''The use of the term 'material' here can be slightly misleading.Many of the 'materials' in this class are actually made up of several more basic materials that are constituted in a way to provide a particular type of function. A thermoelectric, for example, actually consists of multiple layers of different Materials. The resulting assembly is perhaps better described as a simple device. The term 'material', however, has still come to be associated with these devices - largely because of the way they are conceptually thought about and used. Application-oriented thinking thus drives use of the term 'material' here.''

			===== Photoluminescents =====
			an input of radiation energy from the ultraviolet spectrum (or electrical energy for an electroluminescent, chemical reaction for a chemoluminescent) is converted to an output of radiation energy in the visible spectrum.

			===== Photovoltaics =====
			an input of radiation energy from the visible spectrum produces an electricalenergy (the term voltaic refers more to the material which must be able to provide the voltage potential to sustain the current).

			===== Thermoelectrics =====
			an input of electrical current creates a temperature differential on opposite sides of the material. This temperature differential produces a heat engine, essentially a heat pump, allowing thermal energy to be transferred from one junction to the other.

			===== Piezoelectrics =====
			elastic energy (strain) produces an electricity. Mostly, Inputs can be switched and an applied electric energy will produce a deformation (strain).

			===== Electrostrictive=====
			Shape changes under the application of an electric field.
