Research

In order to start our experimental trial, we need to understand the process result in pruney fingers . The duration and temperature are the two parameters that make a difference in our result. So we chose the following paper to complete our understanding of the effect of water aging on fingerprints. 

Effects of water temperature on skin wrinkling

According to this study, the pruning using 40 degree Celsius water will occur in about 5 minutes. For the purpose of our study, we would like to keep the temperature constant to the room temperature. So it will be around 20 degree Celsius. Thus, the duration will increase accordingly.



A similar study shows that the average time to wrinkling in distilled water is 11.5 minutes. The following is a link to this study:
