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 firstname.lastname@example.org.
Time was when sports equipment was made only from common, everyday, low-tech materials. But now sports equipment has a new, high-tech ingredient that is helping players take their game to the next level.
A humanoid diving robot has recovered treasure from the wreck of French King Louis XIV's flagship, untouched for nearly 400 years. The bot not only looks somewhat human-shaped, it's also got stereoscopic humanlike vision, artificial intelligence, and haptic force feedback.
Design collaboration now includes the entire value chain. From suppliers to customers, purchasing to outside experts, the collaborative design team includes internal and external groups. The design process now stretches across the globe in multiple software formats.
