Smart sensor glass fiber, which can become clothes

In the near future, if you wear clothes that you heat up, it will automatically become loose breathable; If you feel you are cold,fiberglass chopped strand mat wrap it tightly. Chinese Academy of Engineering launched the "New Materials International Development Trend Forum," including more than 40 experts, including academicians materials sector under one roof to explore: What is the "ratio of new materials updated material"? Have "features" like sensing capabilities, and can because of the need to change is one of the characteristics of smart materials, such as fiber materials can be used in intelligent clothing.

At present, the application of smart materials to achieve three main categories: a corresponding change in accordance with a voltage different ferroelectric materials, the magnetic field strength of the strain of magnetostrictive material, and can be changed back to the original shape memory metal.

Reporters learned that, Xi'an Jiaotong University materials science, "Changjiang Scholar" Ren Xiaobing led team has successfully developed a new type of smart material - Strain glass. It has a certain flexibility, even if the temperature change does not appear thermal expansion and contraction, but also according to the application scenario "cold thermal expansion." The new material can be used in cell phones, hand ring terminal, also can become a fiberglass clothes, but also widely used in precision instruments. Ren Xiaobing explanation, the strain is actually a glass doped with impurities in a few key shape memory alloy.
