Abstract
• Development of memristor based gas sensors. • Comprehensive Overview of structure and mechanisms of memristor based gas sensors. • Comprehensive study of recent research trends of memristor based gas sensors. • A detailed analysis of simulations related to memristor based gas sensors. • A detailed overview of the future perspectives and challenges of memristor-based gas sensors. The progress of both the Internet of Things (IoT) and several technologies requires new gas sensor systems that are small, low-powered, and carefully designed. A noteworthy approach in regard to achieving this goal is to develop gas sensors that are based on memristors. These sensors are often referred to as gasistors, which are gas sensors plus memristors, and are being extensively studied due to their weightlessness, high-speed recovery, and efficient miniaturized features. The aim of this research is to present an overview of the existing simulations and experimental results on the gasistor for the benefit of future investigations. The gasistor array structure is primarily utilized in simulation results in order to offer an outline of the composite gas detection approach. The experimental results introduced the response characteristics, selectivity, response speed, and recovery speed of various gasistor materials. Different recovery methods, which included pulse and trigger, were introduced in the experimental field. The last session briefly presented the future perspectives and challenges of the gasistor.
