The Electronic Nanomaterials and Devices research group of NTUA has developed a strain sensor which is defined by a pair of interdigitated metallic electrodes with nanoparticles being deposited in the gap between them and arranged in a 2-D configuration. This sensor exhibits much higher sensitivity than conventional metal film sensors, indeed comparable to that of semiconducting strain sensors.
This project will explore fabrication and real time reading of nanoparticle sensor arrays. The proposed high sensitivity, strain sensor arrays show potential for monitoring deformations to estimate structural fatigue and for the early detection of cracks in large marine, aerospace and civil structures enhancing safety. Other application areas include vehicles and train rails, safety equipment, environmental monitoring, homeland security as well as robotics and prosthetics.
Vaggelis Aslanidis was born in Athens, Greece in 1987 and studied Physics at the Physics Department of the University of Crete. He has a master degree from the Department of Applied Mathematics and of the National and Technical University of Athens, on the Monte Carlo simulation and electrical characterization of RRAM devices. Presently, he is a PhD student at the same Department, studding the nanoparticle sensor arrays on flexible substrates
Professor Tsoukalas has developed techniques for room temperature nanoparticle deposition which are based either on ink-jet printing or in vacuum. While ink-jet technique is simpler, it presents problems related with uniformity (controlled deposition density) of NPs within the deposited layer. For that reason we shall focus on vacuum technology.
