Energy Harvesting

The research team is engaged in developing energy harvesting systems for the needs of modern, wireless applications, such as the internet of things (IoT), wireless sensors and switches for SMART technology, biomedical sensors, etc.
Energy harvesting technologies are based on the generation of the surrounding electrical energy emitted from the placement of powered applications. In the case of energy consumption in the hundreds of mW.s and less, these technologies can support the energy-independent operation of modern electronics. In almost all SMART applications there are several types of “unnecessary” energy (radiation – Solar / RF, thermal, mechanical – vibration / shock), which can be efficiently converted into electricity & power and advanced electronics without the need for connection to the power distribution or the use of batteries.

The research team focuses on achieving electricity from vibrations and temperature gradients, a phenomenon common in engineering practice. Especially, vibrational energy harvesting generators in the workplace have been evolving for over 10 years under two international projects (WISE and ESPOSA). A vibration energy harvesting generator is a mechatronic system that uses the properties of mechanical resonators and using physical principles of electromechanical conversion (e.g. Electromagnetic and piezoelectric effect) acquires useful electrical energy at the point of consumption.

The research team also deals with a thermoelectric phenomenon where a thermal gradient can be converted into electricity. A backup power supply has been created within the project TAČR – CAAE.

Recently, the group has been closely cooperating on contractual research in the field of energy harvesting of human movement, from which is expected autonomous power for biomedical sensors and other wearable electronics.

The entire development of these applications is based on the multidisciplinary simulation calculations and virtual prototyping of these devices. At the stage of development of the simulation we can effectively design the parameters of an electromechanical energy harvesting generator for a given application. The resulting product is then tested on a real application.

The results of the research in the field of energy harvesting are regularly published in numerous professional journals and presented at international science conferences.
