Investigation of influence of adsorbtion of CO on characteristics of hold-up line on SAW with ZnO nanorods sensitive element

Abstract

Investigation of influence of adsorbtion of CO on characteristics of hold-up line on SAW with ZnO nanorods sensitive element

Karapetyan G.Ya., Nikolaev, F.L., Lyanguzov N.V., Nesvetaev D.G., Kaidashev E.M.

Structure of  surface acoustic waves(SAW) of CO sensor was developed. SAW sensor include transceiving IDT and catoptric IDT, which is loaded on the impedance of ZnO nanorods. Peak of reflection SAW from IDT clearly observed as result Fourier transformation of time function of pulsed response. IDT loaded on resistance paralleled ZnO nanorods, which depends on the concentration of CO.

Keywords: ZnO nanorods, device on SAW, CO sensor
