Abstract
Gas detector devices, systems, and methods using a Golay cell are described herein. One device includes a microphone having a front surface with a sound collecting aperture for receiving sound, a substrate, a gas cavity formed in the substrate such that the gas cavity is in gas communication with the sound collecting aperture and the front surface forms a side surface of the gas cavity, and a window abutting the substrate to form a side surface of the gas cavity.
