Abstract: Resistive type interdigited electrode (IDE) sensors covered with a mixture of molecularly imprinted polymer (MIP)/conductive polymer (CP) were designed and fabricated to detect terpene gases. The sensor's sensitivity and selectivity were studied for monoterpenes such as α-pinene, limonene, linalool and geraniol. Conductivity changes were used to determine the optimum MIP and CP ratio for the resistive type terpene sensor. A conduction mechanism which explains the correlation between the electrical conductivity and cavity shape was proposed based on the presence of polymer matrix
