From Sensors to Sensor Informatics
Prof. Robert X. Gao
Recent advancement in datascience has opened up new opportunities to complement advanced sensingtechnologies for more effective and efficient extraction of informationembedded in raw sensor data to enable intelligence operation and control ofmachines and processes, leading to the low-cost production of high qualityproducts. Actionable information generated by data analytics has the potentialto increase the accuracy and reliability in predictive modeling of equipmentfailure rates and remaining useful life, consequently improving the robustnessin preventative maintenance scheduling.
This keynote highlightsresearch that integrates process-embedded sensing methods with advanced computationalalgorithms to improve the observability in manufacturing process monitoring andproduct quality control, using polymer injection molding as an example. Thedesign, characterization, and realization of a multivariate sensor withacoustic wireless data transmission capability are introduced, whichoutperforms commercial sensors in predicting the quality attributes ofinjection molded parts, due to integration of advanced computational method.The presentation demonstrates the significance of integrating sensing physicswith data analytics for advancing the science base for manufacturing.

Thin-film Coated Optical Fibre Sensors
Prof. Ignacio R. Matias
During the last decades,much research has been done in the field of fiber optic sensing technology andmore concretely in thin films coated optical fiber sensors. The deposition ofthin-films on optical fibre substrates has permitted, during the last decade,widening the traditional domains of application of optical fibre sensors (e.g.,gyroscopes, strain and temperature) to other research fields. These thin filmscould be built up onto diverse types of fibers and optical architectures. Andthis is possible thanks to modern deposition techniques, which permit coating theoptical fibre with materials, whose properties change as a function of abiological or chemical species. Most of the times, those materials enable theintroduction of losses to the propagation of light in the optical waveguide.And those losses get modulated as a function of the target parameter. Oneparticular type of thin films coated optical fiber sensors are those based onLossy Mode Resonances (LMR), developed by the first time in our laboratories.
In any case, the possibilityof depositing sensitive nano-films with thicknesses under the wavelength of theinterrogating optical light source, make necessary to re-invent many of theclassical photonic sensors and devices. New phenomena and properties areappearing. As in many other fields, there is a lot of work left to do in thisone.
