A system in accordance with an embodiment of the present disclosure comprises at least two electrodes communicatively coupled to a bio-organism. The system further comprises a data acquisition device coupled to the electrodes for receiving analog signals indicative of voltage potential differences in the bio-organism. In addition, the system comprises logic configured to compare a fast Fourier transform (FFT) signature of the signals received with an FFT signature of a bio-organism known to be healthy to determine whether the bio-organism has a particular disease.
