The article "Additive Manufacturing of Sensors: A Comprehensive Review" by Md Jarir Hossain, Bahareh Tavousi Tabatabaei, Mazen Kiki, and Jae-Won Choi provides a comprehensive analysis of the use of additive manufacturing (AM), also known as 3D printing, in the development and manufacturing of sensors. The authors highlight the importance of sensors in modern engineering for detecting environmental changes and monitoring various systems. While conventional manufacturing methods are common, AM has gained popularity due to its efficiency and ability to fabricate complex structures with reduced material waste. The review covers the key processes, materials, and applications of AM in sensor manufacturing, emphasizing the challenges in producing fully 3D-printed sensors. It discusses the limitations in material development and processes that hinder the realization of fully 3D-printed sensors. The role of AM in green technology is also explored, highlighting its potential in sustainable applications. The article introduces the general process of AM, which involves creating a CAD file, converting it to an AM format, transmitting it to the system for fabrication, removing the part from the build plate, and post-processing. It differentiates between fully 3D-printed sensors, which are manufactured entirely using AM techniques, and hybrid 3D-printed sensors, which use AM for certain components but require other parts from traditional methods. Examples of fully 3D-printed sensors include a stretchable, soft pressure sensor made with multi-material AM, while hybrid sensors use pre-made components like sensing coils embedded in ceramic packages. The review aims to provide researchers, engineers, and manufacturers with a detailed understanding of the processes and materials used in AM for sensor fabrication, particularly in the context of sustainable technologies.The article "Additive Manufacturing of Sensors: A Comprehensive Review" by Md Jarir Hossain, Bahareh Tavousi Tabatabaei, Mazen Kiki, and Jae-Won Choi provides a comprehensive analysis of the use of additive manufacturing (AM), also known as 3D printing, in the development and manufacturing of sensors.
