The sensor is a metamaterial, which is any material engineered to have a property rarely seen in nature. “Our sensor consists purely of silicon and contains neither toxic heavy metals nor any ...

Sound-powered sensors stand to save millions of batteries Date: January 29, 2024 Source: ETH Zurich Summary: Researchers are developing a new type of sensor that reacts to certain sound waves ...

They’re using a cheap sound sensor module and an Arduino to catch instantaneous photographs, with students caught in the act of popping balloons. The goal here was to keep things as simple as ...

The advanced noise-canceling system comprises three key components: a high-performance in-ear sound sensor, a custom 11mm driver, and a noise isolation chamber, all supported by powerful algorithms.

Researchers are developing a new type of sensor that reacts to certain sound waves, causing it to vibrate. The sensor is a metamaterial that acquires its special properties through the structuring of ...
