Smart materials Smart materials A shape memory alloy (SMA) (also known as memory metal or smart wire) is a metal that remembers its geometry. After it is deformed, it regains its original geometry by itself during heating (one-way effect) or, at higher ambient temperatures, simply during unloading (pseudo-elasticity). These extraordinary properties are due to a temperature-dependent martensitic phase transformation from a low-symmetry to a highly symmetric crystallographic structure. Those crystal structures are known as martensite and austenite. ...more on Wikipedia about "Shape memory alloy"
A smart fluid is a fluid whose properties (most commonly the viscosity) can be changed by applying an electric field or a magnetic field. ...more on Wikipedia about "Smart fluid"
Smart materials are materials that have one or more properties that can be significantly altered in a controlled fashion by external stimuli, such as stress, temperature, moisture, pH, electric or magnetic fields. ...more on Wikipedia about "Smart material"
Smart windows are electrochromic glass window panes that use a small amount of electricity to alter their transparency value, thus allowing for greater climatic control. Also, another version of smart glass includes that which can block infrared or heat ...more on Wikipedia about "Smart windows"
Smartdust is a hypothetical network of tiny wireless microelectromechanical sensors ( MEMS), robots, or devices, installed with wireless communications, that can detect anything from light and temperature, to vibrations, etc. ...more on Wikipedia about "Smartdust"
