Development of Sensors and Interrogation Systems for Pressure and/or Displacement Measurement using Microstructured Fibers and its Integration in Electrical Bioimpedance Systems
The occurrence of hundreds of thousands of new cases of skin cancer each year in Brazil leads to the necessity to develop reliable and objective instrumentation in order to reduce expensive treatments and related mortality. Electrical Impedance Spectroscopy (EIS) is a non-invasive reliable technique that is widely used in the diagnosis of this disease. However, EIS suffers from errors due to the pressure applied by the probe operator during the examination.
The aim of this project is to develop and integrate an optical pressure sensor in an impedance probe, being this capable to accurately measure these errors due to pressure and compensate them in real time, so they do not alter the final result of the examination, making non-invasive cancer detection more reliable. In order to achieve this goal new pressure sensors will be developed, using micro structured fibers, as well as the signal processing system needed, integrating the sensor and the electrical impedance probe in order to obtain a system that allows an exact and independent reading of the pressure.
The expected products at the end of this project are:
• Pressure and/or displacement sensors based on microstructured fibers;
• Interrogation systems adapted to the developed sensors;
• Adapted bio impedance probe, including in its hardware the pressure sensor;
• Processing signal system that integrates the results of the probe and the pressure measurement system, in real time;
• User friendly interface that allows direct reading in real time;
The performance of this project will be considered adequate when the all system of the interrogation and correction of pressure and bioimpedance probe are obtained.
