Multiple Memory Material Technology

Submit A Comment | View Comments


Shape Memory Alloys (SMA) have generated a lot of recent interest, given their ability to change shape and return to a ‘memorized’ state under different temperature conditions. This so-called hysteresis effect typically involves a transition between two states: the original, cold-forged shape and a new desired shape.

A research team at the University of Waterloo has recently announced an enhancement to this two-way effect, however. The newly developed Multiple Memory Material Technology (MMMT) allows several shape memories to be embedded within a single object, allowing the transition between many shapes at different target temperatures. An object may even be subdivided into different parts with different MMMT properties.

According to University of Waterloo engineer Ibraheem Khan, "This ground-breaking technology makes smart materials even smarter. In essence, a single material can be programmed to remember more shapes, making it smarter than previous technologies."

    Hi I am Elaine Ng Yan Ling and have spent my MA in Design for Textile Futures at Central Saint Martins College of Arts and Design exploring the function of shape-memory materials. I have focused on how the behaviour of natural elements can be manifested in man-made materials to enhance modern architecture and interior design. My design principle is based on Biomimicry, focusing on hybrid materialisation of craft and technology. By programming shape memory materials I explore how tectonic movement can be achieved through natural responses to heat, light and electricity. Techno-Naturology is my latest discovery in the relationship between natural formations and technology design. Techno-Naturology is the use of artificial technology to activate and simulate natural reactions. The concept of ‘Naturology’ tectonic motion is not only about mimicing the behaviour of nature, but also a means of evoking natural movement within an urban landscape. I would like to share my shape memory material in design with you, the following links shows how my design reacts with the shape memory material reacts with the change in temperature. http://vimeo.com/14522270
