Niall O’ Mahony attended the 2016 IEEE International Conference on Advanced Intelligent Mechatronics (AIM) in Banff, Alberta, Canada. The AIM 2016 conference brings together an international community of experts to discuss the state-of-the-art, new research results, perspectives of future developments, and innovative applications relevant to mechatronics, robotics, control, automation, and related areas. The Content presented was Smart Sensors for Process Analytical Technology. The paper presented reviewed the advantages of smart sensors and their role in recent trends in intelligent manufacturing such as the Industrial Internet of Things (IIOT) and Industry 4.0. The paper also presented the selection process for a number of smart sensors for a number of industrial applications dealt with in collaborative work with the ProPAT project. These applications included the Mass flowrate, Moisture content and Temperature of powders in milling and pharmaceutical industries and the Moisture content, Viscosity and Colour of polymer resin in a polymerisation process. This paper has been published in IEEEXplore Conference Proceedings for 2015 IEEE International Conference on Advanced Intelligent Mechatronics (AIM).
