Special Issue Information

Dear Colleagues,

Trends to develop devices mimicking all the mammalian senses have produced both basic and applied research in corresponding directions since the 20th century. So far, we have widely employed sensor units, which have yielded signals regarding electromagnetic radiation (vision), acoustic waves (audition), pressure, temperature, and motion (somatosensation). However, gustation, and olfaction in particular, are extremely difficult to simulate for machine detection due to a variety of substances and interference effects. In many tasks where the selectivity is not demanded as much, chemical sensors have found a market niche because of the high sensitivity obtained recently due to great success in material science and micro- and nano-electronics technologies. To approach the selectivity issue in the same way as the human olfaction system, we have used vector signals or patterns generated by multisensor arrays or single sensors operated under varying conditions. Analyte-specific multisensor patterns are processed by corresponding algorithms recently developed by information technologies. However, s so far these multisensor units have not found a significant market that requires new breakthroughs in the field.

Therefore, we invite applicants to look over the recent advances in multisensor arrays and call for innovative works that explore frontiers and challenges in the field.

The topics of interest include but are not limited to the following:

  • Fundamentals of multisensor arrays
  • Multisensor array technologies
  • Emerging materials for multisensor arrays
  • Integration of sensors to multisensor arrays, features, and challenges
  • Innovative pattern recognition approaches to multisensor signals
  • Interfaces for multisensor arrays
  • Packaging for multisensor array chips
  • Multisensor array networks and IoT
  • Applications of multisensor arrays and artificial intelligence

UAV-based Chemical Detection Systems for Emission Control and Environmental Monitoring: A Review

Javier Burgués 1, 2, * and Santiago Marco 1,2

Abstract: Recent advances in miniaturization of chemical instrumentation and low-cost availability of unmanned aerial vehicles (UAVs) are catalyzing an exponential growth in the use of chemically-enabled UAVs in a variety of civil and research applications, from emission control to precision agriculture, environmental monitoring and early fire detection, among others. UAVs are excellent platforms for in-situ sensing, as they can carry gas detectors directly into the core of toxic gas plumes, minimizing risk to humans, strongly reducing the operational costs as compared to manned aircraft, and providing real-time data with high spatial resolution. However, important limitations exist in terms of the selectivity, limit of detection and response time of current gas detectors, self-localization and obstacle avoidance of UAVs (especially in cluttered indoor scenarios) and flight time. This paper exhaustively reviews the current applications of gas-sensitive UAVs, the types of UAV (fixed-wing, multi-rotor, nano-UAVs) most suitable for each application and their limitations, commonly used gas sensing payloads, and technical considerations regarding the optimal sensor placement to minimize negative effects from self-induced turbulence. We conclude with a discussion about the current challenges, possible solutions and future applications of UAVs equipped with chemical detectors.
