Special Issue Information

Dear Colleagues,

Less budget, resource constraints, and continuous software upgrades are a few problems affecting the implementation of smart cities. The only solution to these problems is to develop smarter technology and a more efficient usage in order to meet the needs of smart cities. A combination of smart sensors, universal platform, Information and Communication Technologies (ICT), Internet of Things (IoT), energy harvesting, cloud computing, and open source technologies, compatible with Next Generation Networks (NGN), will help towards the actual achievement of a smart city. It is now possible to develop significant technology platforms and IoT solutions for smart cities without a massive investment. However, IoT interoperability is still at a very early stage and standardization is difficult to achieve as it is usually led by companies with strong market positions. There is a need for stand-alone development, where large companies will not dictate terms and conditions.

The aim of this Special Issue is to report on the design and development of smart sensors, a universal interfacing platform, along with the IoT framework, extending it to next generation networks (4G, 5G, and future networks) for monitoring parameters of interest with the goal of achieving smart cities. Examples of this work include developing novel sensors for monitoring environmental pollution and other parameters, and making the data available to a wider community through remote access cloud computing. The proposed universal interfacing platform with the IoT frame work will solve many challenging issues and it will significantly boost the growth of IoT-related applications, not just in the environmental monitoring domain, but in the other key areas, such as smart home, wearables, smart city with smart waste management, smart E-metering, smart water supply, intelligent traffic control, smart grid, remote health care applications, etc., in any country. The need is to develop a low-cost solution so that any country, without investing a massive amount of resources, can exploit the research outcomes.

Measurement of moisture at ppm or ppb level is very difficult and the fabrication of such sensors at low cost is always challenging. High sensitivity is an important parameter for trace level (ppm) humidity sensors. Anelectronic detection circuit for interfacing the humidity sensor with high sensitivity requires a simple hardware circuit with few active devices. The recent trends for increasing the sensitivity include fabricating nanoporous film with a very large surface area. In the present work, the sensitivity of a parallel plate capacitive type sensor with metal oxide sensing film has been significantly improved with an aim to detect moisture from 3 to 100 ppm in the industrial process gases used to fabricate semiconductors and other sensitive electronic devices. The sensitivity has been increased by (i) fabricating a nanoporous film of aluminum oxide using the sol-gel method and (ii) increasing the cross-sectional area of a parallel plate capacitor. A novel double sided capacitive structure has been proposed where two capacitors have been fabricated—one on the top and one on the bottom side of a flat alumina substrate—and then the capacitors are connected in parallel. The structure has twice the sensitivity of a single sensor in the same ppm range but the size of the structure remains unchanged. The important characteristics of the sensors such as the sensitivity (S = Δ C Δ p p m × 100 ), the response time (tr), and the recovery time (tc) are determined and compared with a commercial SHAW, UKdew point meter. The fabricated double sided sensor has comparable sensitivity (S = 100%, tr (s) = 28, tc (s) = 40) with the commercial meter (S = 100.5%, tr (s) = 258) but has a faster response time. The proposed method of sensitivity enhancement is simple, and mass producible. Full article
