Abstract

The invention provides a sensor wireless energy collection device model and a calculation method. The sensor wireless energy collection device model comprises an energy collection device and an energy management circuit connected with the energy collection device, wherein the energy collection device comprises an objective table, a spring, a damping meter, a suspension block and a piezoelectric material; the first end of the spring is fixedly connected with the objective table; the second end of the spring is fixedly connected with the bottom of the suspension block and located in the center area of the bottom of the suspension block; and the piezoelectric material and the damping meter are symmetrically arranged in a gap between the objective table and the suspension block, and the thickness of the piezoelectric material is consistent with the height of the gap. While the voltage and current output characteristics of the piezoelectric material are ensured, the calculation speed and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of analog-to-digital converters, in particular to a sensor wireless energy collection device model and a calculation method. Background technique [0002] The establishment of the model of the piezoelectric material magnetic field energy harvesting device is the basis for its theoretical analysis and calculation. For cantilever piezoelectric material energy harvesting devices, using the finite element method can obtain more accurate voltage and current output characteristics of piezoelectric materials, but the calculation speed and efficiency are low. In the actual working process, the vibration amplitude of the energy harvesting device of the cantilever piezoelectric material is generally small and belongs to the single-degree-of-freedom vibration. Rapid modeling analysis improves calculation speed and efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a se...
