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.
The 3D printing revolution seems to have a knack for quickly moving technology ahead by way of collaborative effort and even a little friendly competition -- all of course in the name of scientific advancement.
Advantech has launched a new series of motion-control I/O modules to meet the increased demands that come with more distributed industrial systems that require control of a growing number of axes and devices.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
