Articles: Electronics & Computers
While most cars today run on 12-volt DC batteries, cars in the future will run on 48 volts. This increased voltage could affect ball bearing performance.
Briefs: Motion Control
Conventional pistons are made of a rigid chamber and a piston inside that can slide along the chamber’s inner wall while at the same time maintaining a tight seal. As a result, the piston...
Briefs: Mechanical & Fluid Systems
Typical butterfly valves cannot seal at both ambient and cryogenic temperatures. At cryogenic temperatures, valves grow and shrink, changing critical dimensions such as distance between the disc and seat. Ideally,...

Cell Processing Cartridge for Miniature Cytometer
Portable flow cytometers, especially in handheld or briefcase sizes, have not been available. One reason is the need to support complex, high-pressure fluidics and process cells using a centrifuge and mixing device. A need existed for point-of-care and/or point-of-analysis flow cytometry.
Articles: Motion Control
For most electrical engineers, the simple term “motor” means one thing: an electromagnetic rotary-motion unit. Engineers who need linear rather than rotary motion consider adding a mechanical linkage...
Briefs: Motion Control
Using 3D printers, researchers have created a metamaterial from cubic building blocks that responds to compression forces by a rotation. Usually, this can only be...
Briefs: Mechanical & Fluid Systems
Soft robots are made from soft materials that react to applied voltage with a wide range of motions. Such soft robots contain tremendous potential for future applications, as they adapt to dynamic environments...
Briefs: Test & Measurement
Measurement devices that can withstand the acid rains on Venus, radiation in space, and the heat of car engines are being developed to improve research in these extreme...
Application Briefs: Motion Control
The launch, landing, and overall mission of NASA’s Mars Science Laboratory (MSL) is arguably one of the most daring — and successful — space exploration endeavors ever...
