Electrodermal activity (EDA) usually relates to variations in the electrical properties of palmar or plantar skin sites. EDA responses, namely skin conductance responses (SCRs), skin potential responses (SPRs) and skin susceptance responses (SSRs) are shown to be sensitive indexes of sympathetic nervous system activation and are studied in many research projects. However, the association between EDA responses and the five basic human senses has not been investigated yet. Our study aimed to explore the relationship between the three EDA responses (SCRs, SSRs and SPRs) and the five basic human senses. These three EDA responses were measured simultaneously at the same skin site on each of the 38 volunteers. The tested five senses were sight, hearing, touch, taste and smell. The results showed that the different tested senses led to different degrees of EDA responses due to activation of the sympathetic nervous system and corresponding secretion of sweat. Although a controlled study on the degree of EDA as a function of the strength of each stimulus was not performed, we noted that the largest EDA responses were typically associated with the smell sense test. We conclude that EDA responses could be utilized as measures for examining the sensitivity of the human senses. Hence, EDA devices may have important roles in sensory systems for future clinical applications.

The simplest chemical spray approach has been used to grow the zinc oxide (ZnO) nanorods (NRs). For spraying, a basic perfume automizer was employed. Additionally, utilizing a variety of characterization techniques, the effects of various growth temperatures on the ZnO NRs properties were looked into and evaluated. The results of the investigation demonstrated that the growing temperature significantly affects all-characteristics properties of the ZnO NRs fabricated using the most straightforward spray approach. At various growth temperatures, the average diameters (size) and average crystalline sizes along with (002) of grown ZnO NRs were in the ranges of (47.89-51.29) nm and (44.128-52.565) nm, respectively. The hexagonal wurtzite plane was the optimum direction for ZnO NRs to be oriented, and as growth temperatures are raised. The absorption edge changed toward longer wavelengths and as growth temperature increased, the average absorbance also increased. The optical analysis reveals that the direct Eg. of the produced ZnO NRs lies in the (3.182-3.250) eV range.
