When you need something quietly bending or moving, don’t underestimate SMA’s (or Shape Memory Alloys). The Living Glass project by architects [David Benjamin] and [Soo-in Yang] catalogs an experiment ...

Some metal alloys will "remember" a shape when you heat them to the same temperature they were originally shaped at. So a straight wire made from one of these "shape memory alloys" might change back ...

As Corvette has become more technically advanced, this once-elemental sports car has seen a proliferation of onboard actuators installed throughout its body and driveline. Today’s C6, for example, ...

Smart materials are an interesting field that is growing quickly, and shape memory alloys (SMAs) are one such materials that represent one of the most exciting areas. An SMA can experience ...

The basis of the nickel-titanium shape memory alloy (SMA) class is the intermetallic equiatomic binary alloy NiTi. Its moderate solubility range allows its composition to be changed, and also enables ...

Using Nitinol—a Shape Memory Alloy (SMA) wire—a line of solenoid replacements for commercial applications can be used as a low-mass, low-power, low-cost alternative to larger and more costly ...

Shape memory materials, also known as "metal muscles" or "artificial muscles," have the ability to snap back into their original shape after being stretched, squashed, bent, or otherwise deformed. If ...

Any robot that moves needs actuators—motors that move parts of the robot around. While robot actuators have been around since the dawn of machines, they have some issues. For one, it is very difficult ...
