POLIMI_sensori_novembre 2019 Abstract: A machine is composed by a mechanical structure and a control system (usually a PLC), which is responsible of the appropriate machine working. Sensors act like the link between the mechanics and the control system: they allow the controller to receive a real time feedback on the status of one or more parts of the machine and this information can be used to implement a closed-loop control.  For these reasons, the selection of the sensor type and its features are crucial for guaranteeing the proper operation of the whole machine. This talk aims at providing a description of largely used typologies of sensors for the operational control of industrial equipment (e.g., proximity sensors, displacement sensors, photoelectric sensors). Metrological and technical aspects of different sensing elements and measurement chains will be pointed out. The last part of the lecture will be devoted to an open discussion with the audience on the design of optimal sensors for defined applications, according to specific user requirements. Speaker: Michele Todeschin, Product Engineer Vision and Advanced Sensors, Omron Industrial Automation Europe

Lecturer.  Dr. Hugo TALBOT, PhD Abstract. As in many engineering sectors, numerical simulation has become invaluable, namely for medical education, therapy planning, and implant design. However, simulation softwares remain expensive and require a high level of expertise to be used correctly and effectively. SOFA (Software Open Framework Architecture) is an open-source framework primarily targeted at real-time simulation, with an emphasis on medical simulation. This innovative and collaborative tool is developed by a worldwide community of experts in physics simulations and gathers about 12 years of scientific research. Both academic and industrial developers create their own proprietary simulations based on SOFA, benefiting from its LGPL license. Many research centers actively work and publish using SOFA while five startups have been created for the last five years. This talk will present you SOFA, how to use it and the various fields of applications. Details

Title: "Development of Optical Fiber Sensors for Various Applications", Prof. Kim Taesung Abstract Thanks to light weight/small size, high sensitivity/large band width, long range operation, and harsh environment capability, optical fiber has gained immense attention in sensor field. The optical fiber sensor can be either intrinsic or extrinsic type considering the passage of light and its optical modulation mechanism can be by intensity, phase, wavelength and polarization. It has been used to measure various chemical and physical properties, such as temperature, pH, pressure, humidity, flow rate, gas concentration, liquid level, radiation, displacement, vibration, and chemical species. Prof. Kim Taesung Dr. Taesung Kim received his Bachelor’s in Mechanical Engineering from Seoul National University, Korea in 1994. He received his Master’s, and Ph. D. in Mechanical Engineering from University of Minnesota, USA in 1998 and 2002, respectively, focusing on particle and aerosol research. He joined Seagate Technology in 2002 and worked as Senior and Staff Engineer in Recording Head R&D. Since 2005 Dr. Kim has been a professor in the School of Mechanical Engineering and SKKU Advanced Institute of Nanotechnology (SAINT), Sungkyunkwan University in Suwon, Korea. In 2014, he was appointed as SKKU Young Fellow and started working for SKKU Research & Business Foundation as a Vice President. His research interests include 2-D material synthesis, optical fiber sensors, semiconductor/display manufacturing process (CMP, cleaning and contamination control), and atmospheric/indoor aerosol control.
