Description
Xingyu Wei and co-authors wrote a 2026 paper on a tiny seismometer built on a chip. Such tools record ground shaking, and webs of them on other worlds could show what lies below the surface. Past chip-scale tools had to trade size for low noise or a wide range. This design aims to break that trade-off at last.
The chip is just five point two by six point five millimeters. Wavy-gap comb fingers keep its sensing close to a straight line across a wide range. A second trick uses charge to soften its spring, which cuts noise. Tests show noise near the floor physics allows, and a range wide enough for strong shakes. Live, it caught a magnitude seven quake three thousand, six hundred and eighty-two kilometers away. Its trace matched a standard tool, with ninety-nine point one percent agreement.
