We propose using the current-voltage (I−V) characteristics at the interface between the eutectic gallium-indium alloy (eGaIn) electrode and the hydrogel to detect Streptococcus thermophilus and Bacillus coagulans bacterial concentrations in the range from 10^4 to 10^8 CFU/mL. We apply the feed-forward deep neural network model (multilayer perceptron) for logical data analysis. And training such a machine learning model is performed by an error backpropagation algorithm.
