Entry knowledge

Students who enroll in the subject should be able to explain the physical principles of the curriculum of high school physics. He should know ohm's law, calculate capacitor capacitance, know the difference between own and improper semiconductor, P and N semiconductor, discuss the difference between bipolar and unipolar transistor, diode function and know the basic distribution of energy bands of electromagnetic waves. Generally, knowledge is required at the bachelor level.
Work in the laboratory is subject to the valid qualification of the "instructed worker" according to the Decree. 50/1978 Coll., Which students must acquire before commencement of teaching. Information on this qualification can be found in the Dean's Guidance on Safety Regulations.

Rules for evaluation and completion of the course

The conditions for the successful completion of the course are set by an updated regulation of the course guarantor. Information is given in the test rules on the subject's website.
The content and forms of instruction in the evaluated course are specified by a regulation issued by the lecturer responsible for the course and updated for every academic year.

Aims

Target of the course is to present theory, principles and design of microsensors and microelectromechanical systems (MEMS), to train how to design microsystems and their application.
The student is able to:
- explain the basic properties of sensors
- explain the difference between the sensor and the converter of quantity (sensing element)
- explain principles of microelectromechanical systems,
- describe the basic principles of non-electric quantities
- describe technologies for microsensor fabrication
- explain the difference between a physical, a chemical sensor and a biosensor
