Investigation of the characteristics of energy sources for intelligent environments

Distributed micro-electro-mechanical systems (MEMS) are used in different applications, including the Internet of Things. The paper presents the mathematical models and software that can be applied to research the characteristics of alternative energy sources. The sources can be used in auto-nomous distributed MEMS. We show that the use of the finite element method and ANSYS software allows researching the piezoelectric effect elements properties. We present the data on the applied finite element models for the investigated devices. The minimum modal frequency for all cases was above 40 kHz. Therefore, the sources are suitable for different applications. For all cases delay time was below 13 ms. As a result, we conclude that these alternative energy sources can be used in the Internet of things applications.
