Resumo: | The Additive Manufacturing has been developing more and more, providing numerous advantages to the industry. Among such advantages is the use of materials with conductive properties combined with 3D printing techniques, which enables development of new devices embedded in plastic elements. One of the industries where Additive Manufacturing methods can be applied most successfully is the automotive industry. The electrification of cars, connected cars, autonomous driving, equipment enriched with sensors for better comfort are some of the challenges that this industry faces. Thus, innovation is made in the sense of developing new products to meet the presented challenges, always focusing on the user. Thus, this Master Thesis aims to study, explore and expand these concepts and apply them to the development of a touch sensor, as well as to understand what are the problems of compatibility and electromagnetic interference that can be encountered in automotive environment, specifically, in a smart door for a car. This work begins with the study of Additive Manufacturing methods, the types of measurements for a touch sensor, the sensor designs, and the electromagnetic compatibility and interference issues relevant for such sensors. Useful tools are developed to calculate the sensor capacitance, inductance and resonant frequency. Also, a script is developed to obtain the structural parameters for the resonant frequencies in desired ranges. These tools made it possible to develop a macro to automate creation of 3D structures in CST Studio Suite and thus to be able to simulate such structures for a large set of obtained parameters. Based on the simulations, we designed two sensor structures operating at the desired frequencies and, with the 3D structures ready, moved on to the experimental measurements, producing a PCB prototype for each structure. Thus, by completing these procedures it was concluded that the experimental measurements allowed us to test the developed tools and models and to validate the entire study. |

Dentro delas a utilização de um material com propriedades condutoras e aliado a técnicas de impressão 3D, permite desenvolver novos dispositivos embutidos/incorporados numa peça de plástico. Uma das indústrias que mais se pode aplicar métodos de Manufatura Aditiva é a indústria automóvel. A eletrificação dos automóveis, os carros conetados, condução autónoma, a sonorização dos equipamentos e o conforto são alguns dos desafios que esta indústria enfrenta. Assim, a inovação faz-se no sentido de desenvolvimento de produtos para responder aos desafios apresentados, sempre com o foco no utilizador. Assim, esta Dissertação de Mestrado tem como objetivo estudar, explorar e expandir estes conceitos e aplicá-los ao desenvolvimento de um sensor de toque, além de perceber quais os problemas de compatibilidade e interferências eletromagnéticas num ambiente automóvel, mais concretamente numa porta inteligente para um carro. O trabalho iniciou-se com o estudo dos métodos de Manufatura Aditiva, tipos de medidas para um sensor de toque, design, compatibilidade e interferência eletromagnética destes sensores. Desenvolveram-se ferramentas para auxílio dos cálculos de capacitância, indutância e frequência de ressonância. Também se elaborou um script para obtenção dos parâmetros das frequências de ressonância nas gamas desejadas. Estas ferramentas possibilitaram o desenvolvimento de uma macro para criar as estruturas 3D num simulador e, assim, poder simular os parâmetros obtidos. Com as simulações alcançaram-se duas estruturas nas frequências desejadas e com as estruturas 3D criadas passámos à medição experimental, produzindo uma Printed Circuit Board (PCB) para cada estrutura. Assim, com estes processos, concluiu-se que as nossas medições experimentais permitem validar as ferramentas desenvolvidas, assim como todo o estudo e teoria desenvolvida.2021-09-30T13:53:46Z2021-07-28T00:00:00Z2021-07-28info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10773/32278engMorgado, Davide Manuel Ribeiroinfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2024-02-22T12:02:23Zoai:ria.ua.pt:10773/32278Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-20T03:04:02.921805Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
