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. <br>
