the molecules in the gas samples will absorb that light at different frequencies. It’s almost like a burglar leaving behind a thumbprint at a crime scene. In a previous study, for example, Liang and ...

A highly sensitive, wearable gas sensor for environmental and human health monitoring may soon become commercially available, according to researchers at Penn State and Northeastern University.

What is needed is a device that is impossible to deceive by masking odours, for example with spices, lead researchers Yakov Korenman and Tatiana Kuchmenko said in announcing their invention. Their ...

for example, a motion sensor or a gyroscope, right, which basically use MEMS technology with some algorithms running on top of the sensor, what a gas sensor needs is not just the MEMS technology ...

A team of researchers has developed a MEMS-based gas sensor that leverages pulsed heating and machine learning to accurately identify gases like hydrogen, carbon monoxide, and ammonia, using just ...
