Emergency Power Sources Operating Based on Energy Harvesting Processes for Application in Crisis Situations

This article discusses the use of energy harvesters as emergency power sources during emergencies, crises, and disasters. The climate crisis, population growth, social and political unrest, terrorism, wars, and information chaos all contribute to the increasing likelihood of populations suddenly being deprived of access to electricity. This threat is possible both locally and globally. Regardless of the size, source, or type of emergency, disaster, or crisis, rescue procedures and actions that enable people to function are essential. This requires, among other things, ensuring emergency power sources. Energy harvesting technology can be used to create both primary and supplementary sources of electricity. The authors of the article conducted a comprehensive analysis of this topic and reviewed existing research in this field. Based on literature studies, a number of conclusions were formulated defining the current state, future development directions, and challenges in the use of energy harvesters in crisis situations. The aim of the work is to draw attention to existing threats and to try to direct the interest of scientific teams towards intensifying research in this field, both in terms of the development of cognitive knowledge and the transition from the area of model research to final applications.
