Abstract

Inserting the Industry 4.0 universe into companies is necessary to guarantee their competitiveness and continuity in the market. And, one of the areas in which industry 4.0 and its technologies are most prominent is maintenance, as the use of intelligent mechanisms are capable of promoting the reliability of systems functioning, predicting failures and anticipating problems and breakdowns in equipment., thus contributing to increased performance and reduced aggregate costs. The present study then starts from the idea of using Lab-on-chip technology for the hydraulic fluid and lubricant monitoring system and aims to verify the application of Microelectromechanical Systems (MEMS) in maintenance. From the literary review, it was possible to verify that studies relating the use of microsensors for monitoring lubricants are still scarce and from this, applied research was suggested for this purpose, developing a lab-on-chip that be capable of replacing complex and high-cost laboratory analyses.

Abstract

Este artigo discute o emprego do carbeto de silício (SiC), na forma de substrato e filme fino, em sensores MEMS (Micro-Electro-Mechanical Systems) para aplicações em ambientes sujeitos a condições extremas, especialmente no setor aeroespacial. As propriedades físicas e químicas do SiC que o tornam um material adequado para dispositivos eletrônicos e sensores são descritas. Os conceitos, evolução e aplicações da tecnologia MEMS são apresentados. Uma visão geral sobre o estágio atual de desenvolvimento de sensores MEMS baseados em SiC e uma análise das pesquisas realizadas nesta área no exterior e no Brasil, tanto nas universidades quanto nas indústrias, são também apresentadas. Os recentes avanços alcançados, as dificuldades encontradas e o impacto dessas pesquisas são discutidos, bem como as perspectivas para um futuro próximo. This paper discusses the use of silicon carbide (SiC), in bulk and thin-film form, in MEMS (Micro-Electro-Mechanical Systems) sensors for extreme environment applications, especially in aerospace. The physical and chemical properties of SiC that make it a suitable material for electronic devices and sensors are described. Concepts, developments and applications of MEMS technology are presented. An overview of the current stage of development of SiC-based MEMS sensors and an analysis of research conducted in this area in Brazil and abroad, both in universities and industries are also presented. The recent progress made, difficulties encountered and the impact of these investigations are discussed as well as the outlook for the near future.
