How to Choose an Electronic Load

This article appeared in Evaluation Engineering and has been published here with permission. It is a well-known fact that electronic loads are essential in power-supply and battery-testing applications. However, it can be hard to decide which electronic load is best for an application because of the variety of options in the market today. In this article, we explore the key characteristics of electronic loads and what to consider when starting a new application.   When it comes to electronic loads, there…

Lens Antennas Deliver More Cellular Capacity to Venues at a Lower Cost

What you’ll learn: How the surging demand for electronics and technologies is creating growth opportunities for EMS providers. The role advanced technologies such as AI and automation play in enhancing the outlook of the EMS industry.   The advent of digital computers and their subsequent progress and integration into the mainstream since the 1990s has played a huge role in popularizing electronics usage. Modern electronic devices have long transcended the capacities of their predecessors, becoming increasingly more economical, available, and…

This Week in PowerBites: Radioactive Diamond Batteries?

>> Electronic Design Resources.. >> Library: Article Series.. .. >> Article Series: PowerBites Nickel-Zinc Batteries Challenge Lead and Lithium for Stationary, Industrial Apps Zinc-based batteries are usually associated with the cheap but short-lived, leaky, flashlight-killing carbon-zinc primary cells. However, a new nickel-zinc-based (NiZn) battery chemistry may offer a greener, more cost-effective, solution for indoor and outdoor UPS systems, forklifts, and other specialty vehicle applications. According to ZincFive , its NiZn chemistry is similar to those used in earlier nickel-metal-hydride (NiMH) batteries,…

High-Sensitivity Wide-Range Strain Gauge Mixes Graphene and Silicone-Rubber Matrix

Strain—the response of a material to an applied stress due to an applied force or weight—is an important physical parameter in any application ranging from bridge monitoring to IC die packaging and even human-body measurements. The challenge is that most strain sensors and gauges have sensitivity limits at the lower ranges as well as limited dynamic range, so the quest continues for innovative approaches to strain sensors. Addressing this challenge, a team at University of Sussex (Brighton, U.K.) led by…

Making new materials using AI — ScienceDaily

There is an old saying, “If rubber is the material that opened the way to the ground, aluminum is the one that opened the way to the sky.” New materials were always discovered at each turning point that changed human history. Materials used in memory devices are also drastically evolving with the emergence of new materials such as doped silicon materials, resistance changing materials, and materials that spontaneously magnetize and polarize. How are these new materials made? A research team…

Using robotic assistance to make colonoscopy kinder and easier — ScienceDaily

Scientists have made a breakthrough in their work to develop semi-autonomous colonoscopy, using a robot to guide a medical device into the body. The milestone brings closer the prospect of an intelligent robotic system being able to guide instruments to precise locations in the body to take biopsies or allow internal tissues to be examined. A doctor or nurse would still be on hand to make clinical decisions but the demanding task of manipulating the device is offloaded to a…

It All Comes Down to Risk Assessment

Keeping on-trend with its September Robotics Week, RIA hosted its International Robot Safety Conference (IRSC) virtually. 2020 has been a record-breaking year—for both good and bad. Jeff Pratt, EHS engineer of Tenneco Federal-Mogul Powertrain, discussed ways that users need to be concerned with robot safety in a year that has seen the best value for robot implementation. Most topics Pratt highlighted in his discussion were directly related to the COVID-19 pandemic. For example, robotics can be used to reinforce facial…

Gargees on Mission to Boost Women in Computer Science

Gargees Computer science is rapidly growing as technology becomes more pervasive in our homes and lives. However, the number of women in computer science programs in the U.S. has dropped since 2000. Mizzou Engineering’s Rasha Gargees is on a mission to change that. Gargees was selected this year to participate in the University of Missouri’s Preparing Future Faculty  –  Faculty Diversity Postdoctoral Program. The program prepares scholars and researchers for tenure-track faculty positions. “As both a person from a minority…

Why is Time Important? | Electronic Design

Download this article in PDF format. Electrical connectors play a crucial role in linking various electronic components such as printed circuit board (PCBs), expansion cards, and external data interfaces, and their performance has a direct effect on overall system reliability. As sophisticated electronics become the norm in industrial settings, demand is on the rise for robust components suitable for this market. Highly automated production flows being networked together depend on board-to-board connectors to provide signal connections in an accurate and…
