Abstract | This report talks in detail about the successful synthesis of nanoparticle material Mg(x)Fe(1−x)2O4 (x = 0.1, 0.5 and 0.9) through a simple and inexpensive sol-gel auto-combustion process and its application as a gas sensor. A detailed description of the dependence of liquefied petroleum gas (LPG) sensing performance on the various compositional ratios of Mg(x)Fe(1−x)2O4 (x = 0.1, 0.5 and 0.9) have been investigated. The device was prepared by drop-drying method on lithographic patterned flexible interdigitated electrodes (IDEs). The characterizations revealed that at the specific composition of Mg(x)Fe(1−x)2O4 (x = 0.5), the prepared material performed with supreme sensitivity at 90 °C with respect to the commercially existing gas sensors for 500 ppm of LPG at applied voltage 1 V. Additionally, this device reproduced the similar response in bending test also. The sensor has exhibited related stability even after few days and maintained the stability quite well for several cycles. |
