Course Description

Ceramic Materials and Technologies for Sensors of Physical Quantities

Program

Sensor Technologies

Lecturers:

doc. dr. Tadej Rojac

Goals:

Objectives:
• understanding of principles of operation of sensors of physical quantities,
• knowledge of functional properties of ceramic materials for different sensor types,
• ability to select a suitable technology for an individual sensor,
• ability to predict, measure and analyse sensor characteristics.

Competences:
• ability to select the material with appropriate functional properties,
• ability to design a demo sensor element or structure within given technological boundaries,
• ability to experimentally verify the sensor operation.

Content:

• Up-to-date technological approaches for integrated ceramic sensors of physical quantities.
• Development trends in functional sensor materials: piezoelectric ceramics, piezoresistive composite materials, temperature-dependent resistive composites, electrically conductive thick- and thin-film materials.
• Advanced strategies of modelling-supported design of sensor structures.
• Advanced technologies of ceramic sensors fabrication (bulk, multilayers, thick films, thin films).
• Individual analysis of a case study related to the topic of the student’s PhD research: selection of a suitable sensor material, an innovative technology for sensor realization, prediction of the sensor response and experimental characterization of the sensor and its operation.
