New Nerve Gas Detector Built with Legos and a Smartphone
Researchers at the University of Texas at Austin have developed a way to detect the presence, type and concentration of nerve agents in the field using Legos, a smartphone and a chemical sensor.
AUSTIN, Texas — Researchers at The University of Texas at Austin have designed a way to sense dangerous chemicals using, in part, a simple rig consisting of a smartphone and a box made from Lego bricks, which could help first responders and scientists in the field identify deadly and difficult-to-detect nerve agents such as VX and sarin.
