Abstract: In this paper, the author points out the deficiency and a deviation of the construction of the present intelligent buildings, puts forward the extension and connotation of the intelligent buildings, further discusses the intelligent building materials as a means, and specifically summarizes the forms of a variety of intelligent building materials, such as the concrete, paint, glass and other aspects.

Abstract: The background and design idea of the intelligent materials is introduced. Three elements of intelligent materials are given. Then based on classifying of intelligent materials, the features and applications of intelligent materials are researched.Principle and the latest applications of typical intelligent materials such as optical fiber, shape memory alloys, shape memory polymers, piezoelectric, magnetostrictive materials, fluid material and polymer colloid are analyzed simplely. The research difficulties and the future research focuses of intelligent material are pointed out.

Abstract: The ANSYS finite element techniques were used for modeling and analysis of piezoelectric materials. The single piezoelectric sheet model was presented. The basic characteristic of the piezoelectric materials were analyzed and the affecting factors of characteristics were derived. The high frequency simulation results showed that the displacement responses of piezoelectric materials were very large delay in boost and buck under the high frequency voltage signal, and that was adverse to the vibration control. The low frequency voltage simulation results showed that the displacement response frequency and voltage signal frequency were exactly the same. The model thickness greatly affected its stiffness and indirectly affected its output characteristics.
