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.
Enabling the Future is designing prosthetic appendages modeled more like superhero arms and hands than your average static artificial limbs. And they’re doing it through a website and grassroots movement inspired by two men’s design and creation in 2012 of a metal prosthetic for a child in South Africa.
In order to keep an enterprise truly safe from hackers, cyber security has to go all the way down to the device level. Icon Labs is making the point that security has to be built into device components.
Three days after NASA's MAVEN probe reached Mars, India's Mangalyaan probe went into orbit around the red planet. India's first interplanetary mission, and the first successful Mars probe launched by an Asian nation, has a total project cost of nearly $600 million less than MAVEN's.
