Sensors and Instrumentation technologies.
Biomedical sensors: classification.
Principles of measurement: photoelectric, termoresistive, termoelectric, piezoelectric, pyroelectric, piezoresistive, magnetic, radiation-induced effects; adsorbance and absorbance of chemical species.
Technologies: semiconductors, ceramics, polymeric films, optical fibres.
Structures: impedance (resistive and capacitive sensors of light, force, position, acceleration, magnetic field), diode (photodiodes), transistor (MOSFET, ISFET), self generating (piezoelectric, pyroelectric and electrochemical sensors), optical fibers (step index, graded index, core- e cladding-based sesnors, interferometric sensors).
Applications in medicine and biology of electromagnetic, thermic, mechanical, chemical, radiation and optical sensors.
Technology of electronic instrumentation. Structure of a measurement system. Interface with the sensor, signal conditioning, A/D conversion.
Clinical laboratory measurements Spectrometric instruments (absorption, fluorescence, optical emission spectrometry; UV, visible, NIR, IR and Raman spectrometry; NMR; mass spectrometry). Separation instruments (chromatography, electrophoresis). Imaging instruments (optical, confocal and atomic force microscopy). Electrochemical instruments (Potentiometry, Voltammetry, Conductimetry).
Imaging systems Endoscopy. Computed Radiography. Computed Tomography. Magnetic Resonance Imaging. Nuclear Medicine (Scintigraphy, PET, SPECT). Medical Ultrasonography.
Monitoring equipment Monitors for anaesthesia and critical care medicine. Invasive and noninvasive hemodynamic monitoring (blood pressure, blood flow and volume, cardiac output). Respiratory monitoring (airflow, lung volumes and pressure, gas concentration and transport). Monitoring of motor and nervous system, digestive and excretory system.
A series of Lab activities constitutes a part of the Course.
Students, divided into groups of 4-6 people, will have to develop a project (under the guidance of the Tutors)
The groups will have to design a system composed by
- a simple circuit for the analog conditioning of a given sensor (e.g. potentiometer, NTC, strain-gauge, pressure sensor, photodiode, etc.. )
- an Arduino-based platform for A/D convertion and communication with a PC
- a SW application, developed in Processing, for data acquisition and processing (virtual-instrumentation)
