An applied scientific and technical problem of constructing software for studying the parameters of quartz piezoelectric elements with an interelectrode gap has been solved. An analytical review of the issues arising during parameter modeling, the main approaches to constructing scientific software using universal mathematical packages and narrowly specialized programs, have been conducted. The structure of software components has been developed using object-oriented design and programming principles. A subroutine library for calculating the physical parameters of quartz elements in the Python programming language has been developed. The software can be expanded by using additional refined mathematical models. Figs.: 3. Bibl.: 14 titles.

This paper presents a methodology for analytical calculation and computational simulation using the finite element method for piezoresistive graphite sensor element on flexible polymer substrate, A4 paper. The computer simulation aims to find the region of greatest mechanical tension and deflection of the circular diaphragm set in the circumference edges. The steps for simulation are geometry definition, mesh generation, inclusion of material physical properties and simulation execution. The mathematical modeling of maximum mechanical stress and deflection is described analytically and computationally. The analytical calculations were compared with the computer simulation and presented a relative percentage error of 3.38% for the maximum deflection. The results show that the piezoresistor should be positioned at the edges of the circular diaphragm to take advantage of maximum mechanical stress by defining the best location for graphite film deposition for sensor device designs and fabrications.

“…During the last 20 years piezoresistive pressure sensors have been widely studied and are considered the most popular of MEMS (micro-electro-mechanical system) structure devices. These electronic devices are manufactured with square, rectangular or circular diaphragms [1][2][3]. Pressure sensors are used in industrial process control, environmental monitoring, audio microphone structures, biomedical systems, and other applications.…”

Abstract:In this paper, a simple buoy was used for the power generation tests with a DE powered by waves in the two-dimensional wave tank and the experimental results were analyzed. This research result shows that the optimization of equipment shape and buoy based on the characteristics of the wave for power generation is very important. The extension and contraction of the DE are determined by the motion characteristics of the Heave of the simple shaped buoy model. Furthermore, in order to have freedom in tuning the motion characteristics of Heave, we found that a device capable of setting the spring characteristics of the DE to the smallest possible size with respect to the size of the floating body is necessary. By well matching these factors, high power generation with high efficiency can be realized in a real sea area.
