Special Issue Information

Dear Colleagues,

The development of micromachined sensing devices and sensor networks for industrial, medical, and military applications is an ongoing challenge. Sensing devices and sensor networks are used for safety and security or the characterization of materials.

This Special Issue is focused on micromachined sensor technology and sensor networks for gas, liquid, and solid matter detection using electromagnetics, from microwaves to optical wavelengths. Wireless sensor network technology is welcome and broke down to include wireless components, circuits, and communication systems, all related to wireless sensor nodes or full wireless sensor networks.

Contributions can include basic, theoretical, and applied research for sensing applications, wireless sensors, and sensor networks. Research papers and review articles describing new results regarding micromachined sensing technology, sensor and sensor networks using electromagnetic waves are welcome, and can include but are not limited to radio frequency identification, microwave sensing, optical sensing, surface plasmon resonance, localized surface plasmon resonance, grating coupled surface plasmon resonance, surface-enhanced Raman spectroscopy, wireless sensors, sensor networks and wireless components for sensor nodes or networks.

Abstract
In this study, a micromachined chip in Otto configuration with multiple air-gaps (1.86 μm, 2.42 μm, 3.01 μm, 3.43 μm) was fabricated, and the resonance characteristics for each air-gap was measured with a 980 nm laser source. To verify the variability of the [...] Read more.
In this study, a micromachined chip in Otto configuration with multiple air-gaps (1.86 μm, 2.42 μm, 3.01 μm, 3.43 μm) was fabricated, and the resonance characteristics for each air-gap was measured with a 980 nm laser source. To verify the variability of the reflectance characteristics of the Otto configuration and its applicability to multiple gas detection, the air-gap between the prism and metal film was adjusted by using a commercial piezoactuator. We experimentally verified that the SPR characteristics of the Otto chip configuration have a dependence on the air-gap distance and wavelength of the incident light. When a light source having a wavelength of 977 nm is used, the minimum reflectance becomes 0.22 when the displacement of the piezoactuator is about 9.3 μm. Full article

UAV assisted wireless sensor networks play a key role in the detection of toxic gases and aerosols. UAVs can be used to remotely deploy sensor nodes and then collect gas concentration readings and GPS positioning from them to delimit an affected area. For such purpose, a dual-band communication system is required, supporting GPS reception, and sensor reading data transfer, which is chosen to be at 2.4 GHz using LoRa physical layer. In this work we propose a switched-beam antenna subsystem for the sensor nodes capable not only of satisfying the dual band requirements but also of maximizing communication range or energy consumption through a good antenna polarization match and improved antenna gain. This antenna subsystem is built using dual-port, dual-band, circularly polarized antenna elements, whose design and experimental validation is carefully detailed. A low profile microstrip stacked structure has been used to obtain return loss in both bands better than 15 dB, axial ratios below 1.5 dB, and wide −3 dB beamwidths around 90° and 75° for GPS and 2.4 GHz bands, respectively, thus limiting the gain reduction of the switched-beam system in critical sensor orientations. Special attention has been paid to reduce the coupling between both ports through the optimization of the relative placement of both patches and their feeding points. The measured coupling is below −30 dB. Full article
