Non-linear electrical measurements on Apples and Aloe Vera

This data contains electrical measurements on apples, aloe vera, apple juice and aloe vera liquid. The measurements were done with a three electrode system that enables monopolar recordings under the measurement electrodes. The measurements were done simultaneously with two different measurement electrodes (one silver/silver chloride electrode with a diameter of 2mm and a length of 2mm to 3mm and a clinical stainless steel needle electrode). Different voltages were applied (sinusoidal and triangular with different amplitudes and frequencies) and the resulting currents were measured. Column number one gives information about the subject number, column number 2 which type of subject, columns 3 to 5 give information which voltage was applied, number 6 is the number of measurement within one subject. Column 7 gives information about which quantity (time, applied voltage, measured current 1 (recorded with the Ag/AgCl electrode), measured current 2 (recorded with the clinical stainless steel needle electrode), the data points (from column 8 to the last column) belong to.

本数据集包含针对苹果、芦荟（aloe vera）、苹果汁及芦荟汁的电学测量数据。本次测量采用三电极系统，可在测量电极下方实现单极记录。测量过程同时使用了两种不同的测量电极：一种为直径2mm、长度2mm至3mm的银/氯化银（silver/silver chloride）电极，另一种为临床用不锈钢针式电极。实验施加了涵盖不同幅值与频率的正弦波与三角波在内的多种电压，并对产生的电流进行了测量。
数据集各列的信息说明如下：第1列为样本编号，第2列为样本类型，第3至5列为所施加电压的相关参数，第6列为单一样本内的测量次数。第7列用于明确第8列至末列的数据点所属的物理量类别，具体包括时间、施加电压、经银/氯化银（Ag/AgCl）电极记录的测量电流1，以及经临床不锈钢针式电极记录的测量电流2。
