In smart material system, actuator materials have the ability to change the shape, stiffness, position, natural frequency, damping and/or other mechanical characteristics of the smart material systems in response to changes in temperature, electric field and/or magnetic field.
The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.
