Abstract

A position identification system for wandering elderly people uses BLE to transmit ID information. The objective of this study is to make the BLE module batteryless using a piezoelectric element. The piezoelectric element is mounted on the sole of a shoe, and when pressure is applied to the piezoelectric element by walking, a voltage is generated between both electrodes of the piezoelectric element. This voltage is used to store the necessary power as a battery to operate the BLE module. In this paper, we provide a step-by-step design approach using piezoelectric elements attached to a shoe to power an actual BLE module. We derive an equivalent circuit for the piezoelectric element under walking conditions and, through circuit simulation and actual measurements, clarify the amount of time required to charge the voltage to drive the BLE, demonstrating the possibility of a batteryless BLE module for use in locating a wanderer while they are walking.

摘要

一种用于走失老年人的位置识别系统利用蓝牙低功耗技术（BLE）传输身份信息。本研究的目的是使用压电元件使BLE模块无需电池供电。压电元件安装在鞋底，当行走时对压电元件施加压力，压电元件的两个电极之间会产生电压。该电压用于作为电池存储必要的电力，以操作BLE模块。在本文中，我们提供了一种逐步设计方法，使用附着在鞋子上的压电元件为实际的BLE模块供电。我们推导了行走条件下压电元件的等效电路，并通过电路仿真和实际测量，明确了将电压充电至驱动BLE所需的时间量，证明了在走失者行走时用于定位的无电池BLE模块的可能性。
