Instrumentação e Aquisição de Biossinais

Objectives

This course will address the fundamental concepts of technologies for acquisition and processing of biomedical signals, namely physiological, behavioral and environmental signals. The classic polysomnography exam will be the anchor of the course as it includes a wide range of signals that can be complemented with ambulatory information such as actigraphy, electronic diaries and (ubiquitous) information obtained from the mobile phone. Students should know and understand: 1 -The types of signals and sensors used in biomedical monitoring systems and technologies. 2 -Basic electronics, typical circuits and main transducer and sensors used in this type of systems. 3 -The canonical topology of signal acquisition and processing systems 4 -Typical filtering, conditioning and digital conversion circuits used in this type of equipments. 5- Introduction to embedded systems and digital signal acquisition and processing.

Syllabus

1- Biomedical instrumentation and devices 2- Sensors and transducers a) Physiological data (EEG, ECG, Temperature, Oximetry and respiration) b) Behavioral data (acceleration, gyro, Electronic diaries and cell phone data and logs) c) Environmental data (Light, acoustic noise and temperature) d)Audio and video information 3- Signal filtering and amplification (electronics) 4- Data acquisition and signal processing (embeded systems) 5- Safety of biomedical instruments and devices

Prerequisites

Without prerequisites to attend the curricular unit

Cross Competence Component

The UC allows the development of soft Skills in several of the groups defined in the Relatório Comissão para as Competências Transversais mainly in the context of the project developed in this course that is worth 30% of the final grade of the course. The highlights are the "Critical and Innovative Thinking (Problem Solving Strategies)" components, namely the "Critical Thinking", "Creativity" and "Problem Solving Strategies" components, Interpersonal Skills (group / team work and presentation). of the project), Intrapersonal Skills (autonomy in the realization of the project that promotes the self-discipline and preservation essential for meeting deadlines and obtaining results) and finally the Information and Media Literacy component that is enhanced by the bibliographic research work needed for the realization. the work itself and the corresponding report.

Laboratorial Component

The laboratory component consists of three 3-hour laboratory sessions every other week.

Programming And Computing Component

This UC has a relevant component in computing and programming mainly in the laboratory and project (70%). In the project component students have to do work involving the simulation of dynamic systems with feedback in MatLab environment. Digital control projects are also planned where the programming skills are central.

Ethical Principles

All members of a group are responsible for the group’s work In any assessment every student shall honestly disclose any help received and sources used. In an oral assessment, every student shall be alble to present and answer questions about the entire assignment and solution.
