Wireless sensor technology is a facile way of realizing low cost and miniaturized device for the detection of the volatile organic compounds (VOCs). A wireless electrodeless quartz crystal microbalance with dissipation (WE-QCM-D) sensor array was developed by using a single sensor working in a multi-resonance mode, which obtained an acoustic spectra of the quartz crystal at four harmonics (6 MHz, 18 MHz, 30 MHz and 42 MHz). Multi-responses (frequency shift, and energy dissipation) of WE-QCM-D sensor array were obtained via a ring-down mode and employed as discrimination factors for VOCs. The gas discrimination capability of the WE-QCM-D sensor array has been tested by coating a 100 $\mu$g polyvinylpyrrolidone film on the quartz disc and achieved an optimal recognition rate of 97.5 % with K nearest neighbor algorithm. The results indicate that the single element WE-QCM-D sensor array could be a promising way to realize compact and low-cost VOCs monitoring systems.

无线传感器技术是实现用于检测挥发性有机化合物（VOC）的低成本和小型化设备的简便方法。通过使用在多谐振模式下工作的单个传感器开发了一种无线无耗散无电极石英晶体微天平（WE-QCM-D）传感器阵列，该传感器获得了四次谐波（6 MHz，18 MHz）下的石英晶体声谱。 ，30 MHz和42 MHz）。WE-QCM-D传感器阵列的多响应（频移和能量耗散）通过振铃模式获得，并用作VOC的判别因子。WE-QCM-D传感器阵列的气体识别能力已通过涂覆100$\mu$石英盘上的聚乙烯吡咯烷酮薄膜，并用K最近邻算法获得了97.5％的最佳识别率。结果表明，单元素WE-QCM-D传感器阵列可能是实现紧凑且低成本的VOC监控系统的有前途的方法。
