  2. Match the words and phrases (1-10) from the text with their definitions (a-j).

    smart material d

    a device, such as a photoelectric cell, that receives and responds to a signal or stimulus

    pseudo-elasticity j

    resistance of a fluid to flow

    shape memory effect f

    to include or be included as a part or member of a united whole

    Sensor a

    can significantly change their mechanical properties (such as shape, stiffness, and viscosity), or their thermal, optical, or electromagnetic properties, in a predictable or controllable manner in response to their environment

    Conductivity h

    a field of force surrounding a permanent magnet or a moving charged particle, in which another permanent magnet or moving charge experiences a force 

    Viscosity b

    is an alloy that remembers its shape, and can be returned to that shape after being deformed, by applying heat to the alloy

    magnetic field e

    the amount of space occupied by a three-dimensional object or region of space, expressed in cubic units

    electric field i

    the property of transmitting heat, electricity, or sound

    to incorporate c

    a field of force surrounding a charged particle within which another charged particle experiences a force 

    Volume g

    sometimes called superelasticity, is an elastic (reversible) response to an applied stress, caused by a phase transformation between the austenitic and martensitic phases of a crystal

  3. Fill in the word derived from the word in bold.

1) _smart (Smarter) materials are often considered to be a logical extension of the trajectory in materials development toward more selective and specialized performance. For many centuries one had to accept and work with the properties of a 2) ___standart_ (standardize) material such as wood or 3) _ston_ (stony), designing to accommodate the material’s limitations, whereas during the 20th century one could begin to select or 4) _engineer_ (engineering) the properties of a high performance material to meet a specifically defined need. Smart materials allow even a further specificity – their 5) ­­­­­­­­­­­_properties___ (property) are 6) ___changable__ (change) and thus 7) ­­­­­­­­­­­­_responsive___ (response) totransient needs. For example, photochromic materials change their color (the property of spectral 8) ­­­­­­­­­­­­________ (transmissive) when exposed to light: the more intense the incident light, the darker the surface. This ability to respond to multiple states rather than being optimized for a single state has rendered smart materials a seductive addition to the design palette since buildings are always 9) __________ (confront) with changing conditions. As a result, we are beginning to see many proposals speculating on how smart materials could begin to replace more 10) _________ (convention) building materials.
