Special Issue Information
Dear Colleagues,
This Special Issue of the journal Sensors entitled “Sensor for the Severe Environments” will focus on all aspects of research and development related to this area. The definition of a severe environemnt is wide—it could, for example, include sensors operating in the natural environment, such as chemical sensors in agriculture, extreme industrial environments, such as measurements in turbines, or even environments like that inside the body. Papers which focus on the design and experimental verification of these sensors, as well as papers which focus on the results of sensor field testing in these areas, are particularly welcome. We will also consider linked papers from associated areas, such those looking at as powering or communicating with sensors in such environments. It is the goal of this Special Issue to provide a broad platform for publishing the many rapid advances in the area of severe environments. It is envisioned that by providing this Special Issue and allowing sufficient breadth in the accepted submissions, similarities across varied disciplines may be realized by researchers across application areas and, as such, will provide synergistic comparisons and cross-fertilisations enhancing the overall effort in this difficult area to operate in.

Title: Piezoelectric Sensors as Energy Harvesters for Ultra Low-Power IoT Applications

Abstract: The aim of this paper is to discuss the usability of vibrations as energy sources, for the implementation of energy self-sufficient wireless sensing platforms within the Industrial Internet of Things (IIoT) framework. Industrial contexts foresee the presence of a large number of vibrating assets, like machinery or other types of structures: these may be used to set up plug-and-play sensing platforms that may be easily deployed in hard-to-reach positions. Exploiting vibrations as energy sources, by means of piezoelectric sensors, may lead to the implementation of devices featuring almost infinite life time. In this paper, preliminary measurements as well as extended laboratory tests are proposed to understand the behavior of commercial piezoelectric sensors when employed as energy harvesters. First a general architecture for a vibration-powered LoRaWAN-based sensor node is proposed. Final tests are then performed to identify an ideal trade off between sensor sampling rates and energy availability. The target is to ensure continuous operation of the device while guaranteeing a charging trend of the storage component connected to the system. In this context, an Ultra Low Power Energy Harvesting Integrated Circuit plays a crucial role by ensuring the correct regulation of the output with very high efficiency.
