In this manuscript, the development of SMART sensing technology for applying in the industrial sector has been described. Specifically, the ten S-curve industries of Thailand, according to the 20 years national strategy (from 2018 to 2037), have been emphasized. However, the integration between the SMART sensing technology and the internet of things (IoT) has been considered as an important key for the development of modern sensing technology. The optical fiber sensor technology (OFS) is, consequently, one of the most widely utilized sensors nowadays, due to its superior aspects as compared to other conventional sensors. Moreover, this could be seen from the researches in precision measurements, for examples, the fiber optic sensor for leak detection of methane pipeline, development of continuous biogas measurement system based on OFS, and also the non-invasive fiber optic blood pressure monitoring device, etc. In addition, the artificial intelligence (AI) could be employed as a tool which enhances the performance of the OFS system, as seen with the examples of the artificial neural network (ANN) development in source localization through the fiber optic sensing array, incorporation of the fiber optic sensor and IoT to remotely monitor the structural safety of underground mine, machine learning for assisting the OFS in the prediction of gas generation, and so on. This, thus, improves the OFS into the more intelligent sensing devices. Furthermore, the distinctive points of the presented technologies have been reviewed, with capabilities for the modern applications, which could lead to the future national emergence into “Thailand industry 4.0”.
In this paper, an overview of the laser technology applied for the industrial has been reviewed. In general, this technology was used in several engineering applications such as industrial, medical, science, research sectors, etc. Focusing on the laser technology in the industrial section, it was, normally, employed for many purposes i.e. target marking, welding, drilling, and also cutting. Consequently, the laser cutting technology was, however, divided into three classifications YAG, CO2, and fiber laser, respectively. Each laser types have different advantages and disadvantages depending on the material type. The advantages by using laser cutting compared with the general cutting machines were exploited in terms of narrow kerf, high cutting speed, low heat-affected zone (HAZ), improve efficiency of the cutting process, high accuracy, etc. However, the main objectives from the technology used were increasing of the products and also decreasing the production cost. In the opposite way, some disadvantages of the technology were summarized by complexity to operate, high maintenance cost, and also high power consumption. In Thailand industry, there were many factories used this technology as a cutting process. Unfortunately, only few researches were published. It might explains that this technology were difficulty to develop, high investment, and also easy to import from aboard. For becoming to the Thailand 4.0 community, the Thailand industry might awareness to reduce the importing machine and boosting some policies to create novel innovative / know-how from the own country.
