Recent Advances in Sensors for Chemical Detection Applications

Dear Colleagues,

Chemical detection based on low-cost sensor technologies has become increasingly popular for several emerging applications, such as industrial process control, chemical threat monitoring, green chemistry, environmental sustainability, smart cities, hydrogen economy, energy saving, wearable devices, IoT applications, public health protection, sustainable mobility, autonomous vehicles, and community sensing.

Functional materials are cross-cutting technologies used for chemical detection to provide advanced gas sensors at a laboratory level and real-world testing in many industrial applications. Low-power consumption, high-quality data, and optimal performance are some important parameters used for a new generation of low-cost chemical sensors. Portable sensor systems and wireless sensor networks are typical approaches used to monitor chemical threats in long-term operation.

Current low-cost sensor technologies include numerous types of transducers, such as chemiresistor, electrochemical, transistor, optical, mass-sensitive, catalytic, and other hybrid configurations, evolving quickly with different open questions and considerable challenges, such as sensitivity, selectivity, stability, detection limits, calibration, accuracy, and so on. Understanding the limitations and capabilities of current low-cost sensor technologies for chemical detection is a key issue for future applications.

This Special Issue will focus on low-cost sensor technology, gas sensors, chemical sensors, advanced active materials, sensor nodes, hardware innovations, data communications, system integration, sensor testing, processing/corrections algorithms, machine learning, new solutions, and applications for chemical detection issues. Proper calibration techniques of chemical sensors are necessary, both in laboratory and field applications. Wireless sensor networks will be considered in the context of chemical detection applications.

In this Special Issue, we kindly invite front-line scientists to submit original researches and review articles on Recent Advances in Sensors for Chemical Detection Applications.
