Abstract

In this new age of technological advancement, the usage of vibration for harvesters to provide electrical power for devices can be optimized with the implementation of an energy storing system. This research investigates how a dual-energy harvester that consists of piezoelectric and electromagnetic assembly could store the energy it produced so it can be used whenever necessary. The energy storage system is simulated using Simulink MATLAB that uses a half rectifier to rectify the input voltages that also work as a switching circuit using diodes for each output. The output voltage obtained from energy harvester simulations is 7.55 V and 2.92 V for piezoelectric and electromagnetic respectively. Two types of input with various levels of input (high and/or low) were tested for this energy storage system. It takes 52 minutes for the designed energy storage system to be fully charged from the dual-energy harvester. This outcome from this project provides a possibility for the dual-energy harvester to optimally store a power supply that can be used daily in portable or wearable devices.

用于可穿戴或便携式设备的双能量采集器的能量存储系统

在这个技术进步的新时代，利用振动为收割机提供设备的电力可以通过储能系统的实施进行优化。这项研究调查了由压电和电磁组件组成的双能收集器如何存储其产生的能量，以便在必要时使用。使用Simulink MATLAB对储能系统进行仿真，该系统使用半整流器对输入电压进行整流，并在每个输出端使用二极管作为开关电路。从能量采集器仿真得到的输出电压，压电和电磁分别为7.55 V和2.92 V。该储能系统测试了两种不同输入电平(高电平和/或低电平)的输入类型。设计的储能系统通过双能采集器充满电需要52分钟。该项目的这一成果为双能量采集器提供了一种可能性，即最佳地存储可在便携式或可穿戴设备中日常使用的电源。
