Fig. 2: Digital twin model and electrode sensitivity to the bladder at 50 kHz.
From: Digital twin driven electrode optimization for wearable bladder monitoring via bioimpedance
a Diagram of the digital twin model with domains labeled whose Cole-Cole parameters were specified. b Sensitivity electrode matrix overlaid with cumulative sensitivity to the bladder for simulated volumes. Electrode IDs are included on edge columns, where column one is positioned on the right side of the twin. c Measurement frame absolute sensitivity distribution for all unique combinations of electrode pairings. d Frequency dependent proportion of shared frames across bladder volumes at various percentiles. The Pearson correlation coefficient between the values at varying frequencies is r ≥ 0.999. e Similarity matrix of shared measurement frames in the third quartile across injection current frequencies.
