Figure 7.

Cross‐testing was performed with different shapes of pressure plate contact mechanisms, different sanitizer volumes, and different pressure levels. A) Probabilities of induction with various forms of pressure plate contact mechanisms, different sanitizer volumes, and different pressure levels. B) Box‒and‐whisker plots of the quantitative pressing forces (in grams) measured under four different subjective pressure levels to determine the pressing force threshold. C) Rates of pressure plate activation under different pressing forces at different remaining sanitizer volumes, confirming that a pressing force threshold of 2000 g is appropriate.
