Sound-Off: Do Electric Vehicles Produce High-Frequency Noise?

Many structural factors contribute to automotive noise, whether the vehicle is electric or has an internal combustion engine. In a webinar this week titled, “The Art of NVH Attenuation,” an attendee asked Dr. Pranab Saha, a consultant and expert in acoustics, noise, and vibration control: “Do electric vehicles (EVs) produce unwanted noises at higher frequency than conventionally powered cars?”

Robotic Rubber ‘Skin’ Senses Temperatures. What’s Next?

A rubber “skin” developed at the University of Houston allows a robotic hand to sense the difference between hot and cold temperatures. The semiconductor material supports new applications in stretchable electronics, including medical implants, health monitors, and human-machine interfaces.

Sound-Off: The Imaging Advantages of Blue Light vs. White Light

Digital Image Correlation (DIC) is a non-contact optical method of measuring deformation and strain on a given material. Measurement accuracy, however, depends on contrast, illumination, and light intensity.

Origami Techniques Expand Compacted Spacecraft

Origami has once again inspired engineers at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California. Besides aesthetic beauty, the Japanese tradition of paper-folding addresses a persistent problem faced by JPL engineers: how do you pack the greatest amount of spacecraft into the smallest volume possible?

Webb Telescope Actuators Move with Microscopic Accuracy

The James Webb Space Telescope will be the most powerful space telescope ever built. With a 21-foot diameter, the telescope’s primary mirror is six times larger than the one used by the Hubble Space Telescope. In order for such a large mirror to travel into space, it has to be broken up into multiple segments; in this case, 18 of them. But for the 18 to act as one primary mirror, they have to be adjusted while in orbit.

From the Earth to the Moon: How Robert Goddard Launched Present-Day Spaceflight

On a snowy day in 1926, a 44-year-old physicist named Robert Goddard went with his wife Esther and some colleagues to his Aunt Effie’s ranch in Auburn, Massachusetts. What happened next was not a typical day on the farm. The group tested the first liquid-fueled rocket.

Will we drive on piezoelectric highways?

Today's lead INSIDER story showcased efforts from Lancaster University to create road-ready piezoelectric tiles. The electricity generated from the ceramics (and the vehicles driving over them) could someday be used to power street lamps and traffic lights.

What do you think? Will we drive on piezoelectric highways?
