Kenji Uchino is a professor of engineering at Penn State who developed a small ultrasonic piezoelectric motor that measures less than 2 mm in diameter and is approximately 4 mm long—about the size of a grain of rice. And unlike piezoelectric motors made with tubes of piezoelectric materials, Uchino's motor is made from aluminum, stainless steel, plastic, and brass tubes. Applications for the motor include medical instruments that are disposable and other devices that have small diameters. Because the motor is non-magnetic, its applications include surgical procedures performed with magnetic resonance imaging. Potential non-medical applications include appliances, computers, and wristwatches. "The inside of a wristwatch is filled with gears because tiny electromagnetic motors spin too fast to directly operate a watch," says Uchino. His motor rotates slower, so watches enabled by his motor could be mechanically simpler, he claims. For more information, send e-mail to email@example.com.
Why would the biggest connector company in the world design and build the first fully functional 3D-printed motorcycle? To show TE Connectivity's engineers what the technology can really do in making working load-bearing production parts, and free up their thinking when approaching design problems.
The enhanced ST8 includes new functionality designed to help users accelerate design speed and improve the user’s ability to leverage synchronous technology. The update offers greater flexibility in choice of platform and purchasing options, according to the company.
“How can European standards affect me, especially since I only use machines built in the US?” This is a common question, and one way to answer this is to look at how machine safety is enforced, where the information comes from, and how well you can prove you followed the regulations.
