He has published more than 150 papers in international journals (h-index=21) and he gave more than 30 invited talks in international conferences. He is the: Representative of Greece in the Universal Network of Magnetic NDE; Vice-Chair of the Hellenic NDT Association; Chair of the European Magnetic Sensor and Actuator (EMSA) Conference; Chair of the International Conference on Materials and Applications for Sensors and Transducers (IC-MAST); Editor-in-Chief in “Journal of Materials and Applications for Sensors and Transducers”; Regional Editor in “Recent Patents in Material Science”; Editorial Board in “Journal of Electrical Engineering”, “Journal of Automation Mobile Robotics and Intelligent Systems” and “Measurement Automation Robotics”

 

Abstract:

This report centers at different types of displacement sensor s based on magnetostriction delay line (MDL) theories and technologies. Displacement sensor which is anhysteretic and highly sensitive can be applied to probing soft magnet, hard manet and Coordinate displacement in metal, with a sensitivity of 1-10 pm magnitude.
