New process promises to revolutionize manufacturing of products

02.09.2010
A new "smart materials" process - Multiple Memory Material Technology - developed by University of Waterloo engineering researchers promises to revolutionize the manufacture of diverse products such as medical devices, microelectromechanical systems (MEMS), printers, hard drives, automotive components, valves and actuators.

The breakthrough technology will provide engineers with much more freedom and creativity by enabling far greater functionality to be incorporated into medical devices such as stents, braces and hearing aids than is currently possible.

Smart materials, also known as shape memory alloys, have been around for several decades and are well known for their ability to remember a pre-determined shape.

Traditional memory materials remember one shape at one temperature and a second shape at a different temperature. Until now they have been limited to change shape at only one temperature. Now with the new Waterloo technology they can remember multiple different memories, each one with a different shape.

"This ground-breaking technology makes smart materials even smarter," said Ibraheem Khan, a research engineer and graduate student working with Norman Zhou, a professor of mechanical and mechatronics engineering. "We have developed a technology that embeds several memories in a monolithic smart material. In essence, a single material can be programmed to remember more shapes, making it smarter than previous technologies."

The patent pending technology, which is available for licensing, allows virtually any memory material to be quickly and easily embedded with additional local memories.

The transition zone area can be as small as a few microns in width with multiple zones, each having a discrete transition temperature. As the processed shape memory material is subject to changing temperature, each treated zone will change shape at its respective transition temperature. As well, transition zones created side-by-side allow for a unique and smooth shape change in response to changing temperature.

Several prototypes have been developed to demonstrate this pioneering technology.

One mimics a transformer robot. The robot's limbs transform with increasing temperature at discrete temperatures, whereas in conventional shape memory technology this is limited to only one transformation temperature.

A video demonstrating the miniature robot can be seen at: www.research.uwaterloo.ca/watco/technologies/eng_memory_material.asp

The engineering technology was developed in the Centre for Advanced Materials Joining, based in Waterloo's department of mechanical and mechatronics engineering.

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
