Time-synchronized Energy Harvesting Traces

32h of time-synchronized energy-harvesting traces from 5 different scenarios involving solar panels and piezoelectric harvesters. The data was recorded with, a measurement tool that records time-synchronized voltage and current traces from one or more energy-harvesting nodes with high rate and resolution.

The jogging dataset comprises traces from two participants, each equipped with two piezoelectric harvester at the ankles and a solar panel at the left wrist. The two participants run together for an hour in a public park, including short walking and standing breaks.

For the stairs dataset, we recorded traces from six solar panels that are embedded into the surface of an outdoor stair in front of a lecture hall. Over the course of one hour, numerous students pass the stairs, leading to temporary shadowing effects on some or all of the solar panels.

The office dataset comprises traces from five solar panels mounted on the doorframe and walls of an office with fluorescent lights. During the one-hour recording, people enter and leave the office and operate the lights.

The cars dataset contains traces from two cars. Each car is equipped with three piezoelectric harvesters mounted on the windshield, the dashboard, and in the trunk. The cars drive for two hours in convoy over a variety of roads.

The washer dataset includes five traces from piezoelectric harvesters mounted on a WPB4700H industrial washing machine, while the machine runs a washing program with maximum load for 45 minutes.

本数据集涵盖5种不同场景下、总时长32小时的时间同步能量收集轨迹数据，涉及太阳能板（solar panels）与压电能量收集器（piezoelectric harvester）两类采集设备。数据通过一款测量工具采集，该工具可对一个或多个能量收集节点的电压与电流轨迹进行高采样率、高分辨率的时间同步记录。

慢跑数据集（Jogging Dataset）包含两名参与者的采集轨迹，每名参与者的脚踝处搭载两台压电能量收集器，左手腕搭载一块太阳能板。两名参与者在公共公园一同跑步一小时，期间包含短暂的步行与站立休息时段。

楼梯数据集（Stairs Dataset）采集了嵌入至教学楼前室外楼梯表面的六块太阳能板的轨迹数据。一小时的录制过程中，大量学生途经楼梯，会对部分或全部太阳能板造成临时遮挡效应。

办公室数据集（Office Dataset）包含安装于某间办公室门框与墙面的五块太阳能板的轨迹数据，该办公室配备荧光灯具。一小时录制期间，人员进出办公室并操控灯具。

车辆数据集（Cars Dataset）包含两台车辆的采集轨迹。每台车辆的挡风玻璃、仪表盘与后备箱处分别搭载三台压电能量收集器。两台车辆以车队形式在多种路况下行驶两小时。

洗衣机数据集（Washer Dataset）包含安装于WPB4700H型工业洗衣机上的五组压电能量收集器轨迹数据，洗衣机以满负载运行45分钟的洗涤程序。
