Researchers in China developed a 433 MHz passive wireless surface acoustic wave (WSAW) gas sensor for dimethyl methyl phosphonate (DMMP) detection. It includes a YZ lithium niobate (LiNbO3) substrate with metallic interdigital transducers (IDTs) etched on it, and an antenna was placed near the IDT… read more. Open Access TECHNICAL ARTICLE
