Course detail
Energy Harvesting
FSI-RAE Acad. year: 2020/2021 Winter semester
The course “Energy Harvesting” deals with introduction of unique ways of the energy generating from surroundings. Currently remote electronics, autonomous low power devices and wireless sensors are powered by batteries. One possibility to overcome energy limitations of batteries or possibly fully substitute batteries is to harvest energy from the environment to power the electronics. The ambient energy is available in the form of radiation, thermal energy and mechanical energy of the environment. The course “Energy Harvesting” is focused on energy harvesting from mechanical energy of vibrations, shocks, deformation, human behaviour etc., and simulation modelling of energy harvesting systems.

Learning outcomes of the course unit
The “Energy harvesting” deals with overview of independent ways of generating energy from surroundings for autonomous supplying of wireless sensors, remote electronics and low power devices. Students will be able to: Analyze of ambient energy for energy harvesting from the concrete industrial system. Select the best way of supplying of modern autonomous electronics. Simulation modelling of electro-mechanical conversion.
Prerequisites
Kinematics and dynamics, Solving the 2nd order differential equations, Laws of electromechanical energy conversion, Laws of conservation of energy, Basic knowledge of measurement of electrical and non-electrical quantities, Simulation software Matlab-Simulink and ANSYS (basic knowledge).
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes
The students will solve reports from the exercises and labs and students create the final project, which are necessary for awarding the course-unit credit.
Aims
The objective of the course “Energy Harvesting” is to familiarize students with basic principles of energy harvesting systems as well as methods of electro-mechanical conversion, principle of photovoltaic cells and thermoelectric generators. The emphasis is on understanding the physical principles of energy harvesting methods mainly electro-mechanical conversion and simulation modelling of such mechatronic systems.
Specification of controlled education, way of implementation and compensation for absences
