Anti-Friction Coatings: How to Eliminate Noise for the Life of Interior Plastic Components

In conjunction with SAE Modern passenger cars are equipped with sophisticated measures to avoid propagation of noise from the engine and gearboxes into the passenger compartment, which creates a very comfortable environment for car occupants. On the other hand, this enables “new noises” to become audible – in particular, those generated by the sliding of plastic components made of thermoplastics having poor affinity under the tribological aspect.

Disposable 'Ninja-Star' Battery Supports Biosensors

A Binghamton University researcher's new disposable battery folds like an origami ninja star. The microbial fuel cell could power biosensors and other small devices in challenging field conditions.Engineer Seokheun “Sean” Choi's new design folds into a star with one inlet at its center and the electrical contacts at the points of each side. After a few drops of dirty water are placed into the inlet, the device can be opened into a Frisbee-like ring to allow each of the eight fuel cells to work. Each module is a sandwich of five functional layers with its own anode, proton exchange membrane, and air-cathode. The device uses filter paper, carbon cloth (for the anode), and copper tape. The team’s next goal is to produce a fully paper-based device that has the power density of the new design and a lower price tag. The current device, about 2.5-inches wide, costs about 70 cents to make. According to Choi, the device could support the use of more sophisticated fluorescent or electrochemical biosensors in developing countries.SourceAlso: Learn about NASA's Origami-Inspired Folding of Thick, Rigid Panels.

How to Prevent Step Losses with Stepper Motors

While stepper motors are an excellent solution for many applications, a key concern is step losses. However, in most instances step losses can be prevented or corrected. It is important to remember that a stepper motor does not operate like a DC motor. This white paper from MICROMO engineers provides guidance to determine step losses or non-operation across a variety of applications.

Would you like to have a voice-based personal assistant?

This week's Question: Google, Amazon, and Apple have developed — or are in the process of developing — voice-based personal assistants that "listen" and respond to verbal commands. The Amazon Echo, a 9-inch tall, voice-operated cylindrical speaker powered by an artificial-intelligence agent, was released last year; Google launched its Home speaker at the company's I/O event last month; and Apple is opening its Siri voice assistant to outside app developers. With the technologies, a user's verbal commands could soon initiate a variety of actions: controlling the lights in your home, turning on your car, playing video on your TV, or accessing the Internet, for example. The assistants could also provide increasingly personalized information based on one's specific commands and actions.

The Role of Multi-domain Dynamic Models for Functional Verification in Model-based Systems Engineering

Much has been made of the power of Model-based Systems Engineering (MBSE) as a formal method for capturing and managing design requirements for complex engineering systems. But what does MBSE really mean for the engineering design organization? Whenever a proponent of MBSE speaks with a mechanical or electrical design engineer on the topic, they are likely speaking different languages. Even the phrase “systems engineering” can have very different meanings!

'On the Fly' 3D Printer Adjusts to Design Changes

In conventional 3D printing, a nozzle scans across a stage: depositing drops of plastic, rising slightly after each pass, and building an object in a series of layers. A new "on-the-fly" prototyping system from Cornell University allows the designer to make refinements while printing is in progress.

Optimizing Electronics for Medical Applications

Two years ago, in Medical Design Briefs, Derek Hunt offered some insight into the benefits of Complementary Metal-Oxide Semiconductor (CMOS) technology in the miniaturization of medical devices. CMOS has been around for decades and aside from the size benefits which will be discussed shortly, the technology also brings significant cost savings and performance improvements to the medical world. Readers who are currently engaged in the design of medical electronics already recognize this. It’s actually difficult to design such products today without incorporating CMOS devices. And because medical devices often contain many analog components, there remains one critical decision point designers must address and that is whether to design with standard off-the-shelf standard analog products or engage with a semiconductor company to produce a custom analog chip for the application.
