This book presents the theoretical basis and applications of biomedical signal analysis and processing. Initially, the nature of the most common biomedical signals, such as electroencephalography, electromyography, electrocardiography and others, is described. The theoretical basis of linear signal processing is summarized, with continuous and discrete representation, linear filters and convolutions, Fourier and Wavelets transforms. Machine Learning concepts are also presented, from classic methods to deep neural networks. Finally, several applications in neuroscience are presented and discussed, involving diagnosis and therapy, in addition to other applications.
Biosensors are considered a special sub classification of biomedical sensors: a biological recognition element, such as a purified enzyme, antibody, or receptor, that acts as a mediator and provides the selectivity required to sense the chemical component (usually referred to as the analyte) of interest, and a supporting structure that also acts as a transducer and is in close contact with the biological sensing sensed by the biological recognition element into a quantifiable measurement technique. The transducer’s function is to translate the biological reaction into an optical, electrical, or physical signal proportionate to the concentration of a certain chemical. A blood pH sensor, for example, is not a biosensor according to this definition, despite the fact that it monitors a physiologically significant variable. It’s nothing more than a chemical sensor that can be used to measure biological quantities.
In optical devices like ring resonator, mach zehender interferometer, and many other devices, the light passes through the waveguide and these devices can be used for various biomedical applications. These devices are helpful in point-of-care applications. Because of their sensitivity, specificity, speed, simplicity, and costeffectiveness, nanomaterial-based biosensors have found widespread application in environmental and medical applications. Through the rapid and exact examination of numerous chemicals, silicon-based photonic biosensors integrated into semiconductor chip technology can lead to considerable breakthroughs in point-of-care applications, food diagnostics, and environmental monitoring. The ability to create sensor arrays is another advantage of SOI-based biosensors. This enables for the simultaneous detection of many drugs. Interferometric or resonant structures can be used to build the SOI-based photonic biosensor. Enzyme-linked immunosorbent assay, electrochemical sensor, bilayer lipid membranes, high performance liquid chromatography, micro-electrode immunoassay, field immunoassay, and surface plasmon resonance spectroscopy are examples of competitive traditional biosensing techniques that are already commercially used. The key advantages of SOI-based ring resonators over standard benchtop electrochemical instruments are their small size, scalable mass-production, and quick readout.
