Researchers atMIT德国研究中心的Helmholtz协会发明了一类材料，因为它们在对热量反应时变化时的敏捷性如此出色，它们可能被描述为杂技塑料。欧洲杯足球竞彩
新材料（称为“三欧洲杯足球竞彩形材料”）可以假定三种不同的形状，每种形状取决于施加多少热量。
This landmark achievement comes from the laboratories of chemical engineer Robert Langer of MIT and polymer chemist Andreas Lendlein of the Helmholtz Institute in Teltow, Germany.
"Triple-shape materials can switch from shape A, then to shape B, and on to shape C," Lendlein explained. "Using two, rather than just one, shape-changes offers unique opportunities for applications such as 'intelligent' stents, or 'smart' fastener systems" for use in assembling commercial products, he said.
由新的塑料制成的“智能支架”可以假定三种不同的形状来促进医疗程序：它会假定插入的方便的椭圆形形状，然后是一个完全充气的圆形，用于在血管，导管或其他圆柱形内临时使用器官，最后是压缩的圆柱形形状，可轻松去除。
The triple-shape-shift from shape A to B to C could also have applications in industry. In factories, changeable plastic fasteners could be implanted in, or attached to, one part, then heated to extend an arm to another part. With further heating, the fastener would change shape yet again to lock itself in place. In effect, it would be an automated form of self-assembly.
Langer, an MIT Institute Professor, said, "It's like a new principle in materials, and it will be producing new opportunities. I imagine that if you had things you want to install, and then remove," the ability to change their shapes at will could be useful. "It's the first time I've seen something that will go from shape A to shape B and then shape C."
关于这项工作的论文将发表在美国国家科学院议会论文集的11月28日发表。欧洲杯线上买球Langer和Lendlein的合着者是博士学位。学生Ingo Bellin和聚合物化学家Steffen Kelch。两者都与Lendlein合作，Lendlein领导柏林Teltow的生物材料开发中心。
In earlier work, Lendlein and Langer invented a dual-shape class of materials, leading to what they call a "smart suture" that changes shape as needed for surgery (Smart suture is first application of novel MIT polymer), and they introduced a plastic that changes shape when activated by light (Intelligent plastics change shape with light). In November 2005 they received the World Technology Network Award for these achievements.
