Additive Manufacturing (AM) is one of the most dominant technologies of the 21st century and is leading to a new era of industrial revolution. Over the past years, AM has drawn significant attention from industry and academia to promote the development of components with complex geometry, advanced functionality, reduced design-to-production time, and high efficiency in low-volume production. Given the unique advantages of additive manufacturing, it has a significant potential for penetration into a variety of application sectors including aerospace, energy, automotive, healthcare, national defense, and consumer products. One of the emerging areas of application for AM is advanced sensing systems. This seminar focuses on multi-scale (i.e., micro- and macro-scale) laserbased AM technologies for the development of optical-based sensing devices.
Hamid Alemohammad will elaborate on the development of optomechanical sensors for structural and thermal monitoring in harsh environments, metal embedded optical fiber sensors, and multi-parameter opto-chemical sensors. The fabrication of these sensing systems have been realized by a combination of advanced manufacturing techniques including laser Direct Write (DW) technology, Laser Metal Deposition (LMD), and ultrafast laser micro-fabrication. In this seminar, He will discuss the AM process development, customization, and material characterization, study of the mechanical properties and microstructural characteristics of multi-layered additively manufactured sensing components, and multi-physics modeling for the design of the advanced sensor systems. The seminar will be concluded with a multi-disciplinary research plan on advanced manufacturing, especially hybrid processes (i.e., subtractive/ additive), for the realization of cyber-optical systems, photonic devices and sensors, smart structures, and embedded sensors. This research plan embraces topics related to advanced manufacturing process development, process modeling and control, quality assurance, and functional components design and modeling.
Hamid Alemohammad holds a PhD in Mechanical Engineering from the University of Waterloo. He is currently affiliated with Waterloo Centre for Automotive Research (WatCAR) as Research Associate AOMS Technologies Inc., a startup company spun off of his academic research. He has several of academic and industrial experience in the areas of advanced manufacturing, sensors and measurement systems, and laser material processing. Dr. Alemohammad’s academic and industrial research contributions have been highlighted in peer‐reviewed scholarly articles, commercialized patents, edited book, book chapters, and conference papers. In recognition of his research contributions, he has received several awards and fellowships from Natural Sciences and Engineering Research Council of Canada (NSERC), Ontario Centres of Excellence (OCE), Ontario Ministry of Research and Innovation (MRI), and Ontario Graduate Scholarship (OGS) program. His academic and industrial research has resulted in the development of two patents, both are in the process of commercialization. One of his patents is the backbone of AOMS Technologies Inc. with the mandate to commercialize state-of-the-art academic research outcomes on embedded optomechanical sensors for oil and gas applications. Alemohammad also holds the Certificate in University Teaching (CUT) from the University of Waterloo and has instructed courses in the areas of mechatronics, control systems, and mechanical engineering design.
