Why Your Leak Test Doesn’t Measure Up – and What Data Can Do About It

On the manufacturing line, the struggle to test for and address leaks that lead to faulty parts and warranty claims is nothing new — but rising expectations for product quality and reliability are putting leak tests to the test. How can quality engineers meet Industry 4.0 requirements for emission control, performance and reliability while coping with increased production volumes that demand shortened cycle times? Make the test better with data.

Data Logger Aids in Development of New Vehicles

A new data logger developed by Fraunhofer researchers simultaneously collects data from vehicles with combustion engines, electric drives, external sensors, and location data, and permits the development of new hybrid and electric vehicles. Once installed in a car, it records all the relevant operational data from the trips the car makes over a period of several weeks or months, enabling evaluation of how a car is used, including characteristics such as route profiles or driving style – when does the driver drive more cautiously, when more aggressively?

High-Altitude Radiation Tests Will Protect Airline Travelers

The RaD-X payload ascended into the stratosphere to measure cosmic radiation coming from the Sun and interstellar space. (NASA)

Imagine you’re sitting on an airplane cruising at 36,000 feet. Just above you, high-energy particles, called cosmic rays, are zooming in from outer space. While we are largely protected from this radiation on the ground, up in the thin atmosphere of the stratosphere, these particles can affect humans and electronics alike.

Reliability Testing of High-Power Devices

Before a new high-power semiconductor device can be used for industrial applications, it must be thoroughly tested to determine if it will survive environmental stresses and continue to meet specifications. This is especially true for the latest wide-bandgap semiconductor materials such as silicon carbide (SiC) and gallium nitride (GaN) to ensure they can withstand high voltage and temperatures.

Electronic Device Monitors the Heart and Recognizes Speech

Researchers from the University of Colorado Boulder and Northwestern University have developed a tiny, soft, and wearable acoustic sensor that measures vibrations in the human body, allowing them to monitor human heart health and recognize spoken words. The stretchable device captures physiological sound signals from the body, has physical properties matched with human skin, and can be mounted on nearly any surface of the body. The sensor resembles a small Band-Aid®, weighs less than one-hundredth of an ounce, and can gather continuous physiological data.
