Thanks to patented heat sink technology that improves control of shape change, this actuator is available in 1 million or 5 million cycle versions.
The NanoMuscle Actuator exploits the properties of shape-memory alloys (SMA) to produce movement. The result: a linear actuator that costs less than a dollar, is three to five times more efficient than existing motors and 1/3 the weight, traverses 4 mm silently in 100 millisec, and is strong enough to move 140-gm loads.
The motor uses hair-thin nickel-titanium SMA wires, stacked plates of stamped steel, and crimped interconnects. Adding sliding planes increases stroke length. The device, half the length of a matchstick and about the width of a paper clip, includes a control system and feedback to achieve repeatable 40-micron accuracy.

Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
