The student must know the principle of semiconductor operation electronic nose and chemical sensor; main characteristics of chemical sensors; the principle of operation of the field-effect transistor; powder and film conductivity sensors type; conductive polymers; volume acoustic waves; surface acoustic waves; calorimetric sensors; sensors on optical fiber; dimensional wiring in silicon; design features and characteristics of luminescent, optical, resistive and barrier sensors on nanosilicon. The student must be able to conduct a literature and patent search for analogues and prototypes of the given sensors; use and analyze algorithms for calculating parameters of sensor matrices; explain catalytic and adsorption-desorption processes on the surface of a solid body; to calculate the concentration of analyte molecules from measurements of the signals of resistive type sensors; describe equivalent circuits and calculate parameters of calorimetric and acoustic membrane sensors.

Full-time form

The educational discipline "Physical principles of sensorics" is based on a cycle of professional and practical training disciplines, in particular, such as "Electricity and magnetism", "Optics", "Atomic physics", "Quantum mechanics", "Differential equations", "Mathematical physics", "Radio electronics", "Oscillations and waves".

The discipline program examines the physical phenomena that form the basis of the work of gas and biosensors, the semiconductor structures of micro-, opto- and nano-electronics, on the basis of which sensors are created, algorithms and methods of measuring the parameters of these structures, the basics of technology production and metrology. In particular, basic information about the electronic nose, methods of processing signals from multisensors, gas sensors based on metal-oxide semiconductors and based on surface-barrier structures (GasFET, ISFET, MIS) are presented; fluorescent, optical and electrical transducers based on nanocrystalline semiconductors, sensors based on polymers, acoustic waves, thermal and optical phenomena.

Lectures, seminar classes, independent work.

Semester assessment: there are two academic semesters content modules: To determine the level of achievement of learning outcomes, the tasks for the modular control work test the ability to solve specific problems. Writing the 1st is mandatory for admission to the exam and 2nd modular test papers with a score of at least 15 points. The final evaluation is in the form of an exam, the form of the exam is written and oral. In total, you can get from 0 for the exam up to 40 points. A condition for achieving a positive grade for a discipline is to obtain at least 60 points, while the exam grade cannot be less than 24 points.
