MOTION CONTROL: Steinmeyer Inc. has announced a new product to its extensive line of miniature ball screws. These 5-mm diameter screws are the perfect solution in applications such as micromanipulators, miniature robotics and compact actuators. Available in four nut styles: series 1112 single nut with connecting thread without wipers; series 1412 is a single nut with double flange and wipers on both ends; series 1214 is a cylindrical nut without wipers; and series 2422 is the company’s “quiet line” series, with a single nut that uses end-cap ball returns manufactured from plastic rather than metal tubes, making the screw virtually noiseless. All are available with leads ranging from 0.5 3 mm and offer a maximum speed of 4500 RPM.
The 2014 Ig Nobel Prize in Physics was awarded to Dr. Kiyoshi Mabuchi and his team members for their work measuring the slipperiness of banana peels. Turns out they're slipperier with the yellow side up.
Many scientists have been working battery-free ways to power wearable electronics that can replace bulky battery packs, particularly through the use of energy-harvesting materials. Now a team of researchers in China have upped the game by developing a lightweight and flexible solar cell that can be woven into two-way energy-harvesting fabric.
