Acoustic impedance-based surface acoustic wave chip for gas leak detection and respiratory monitoring
Abstract Acoustic impedance enables many interesting acoustic applications. However, acoustic impedance for gas sensing is rare and difficult. Here we introduce a micro-nano surface acoustic wave (SAW) chip based on the acoustic impedance effect to achieve ultra-fast and wide-range gas sensing. We t...
