From: A reconfigurable and conformal liquid sensor for ambulatory cardiac monitoring
Magnetic mapping of the liquid sensor along its z-axis before (a) and after stretching (b). c Magnetic field strength of the liquid sensor along its z-axis before and after stretching. Magnetic mapping of the liquid sensor along its y-axis before (d) and after stretching (e). f Magnetic field strength of the liquid sensor along its y-axis before and after stretching. Magnetic mapping of the liquid sensor along its x-axis before (g) and after stretching (h). i Magnetic field strength of the liquid sensor along its x-axis before and after stretching. j Liquid sensor was flipped over when it was attached to wet skin. Scale bar, 5 mm. k Magnetic field of the PFM measured for three hours. l Liquid cardiac sensors tested on dry skin and on sweaty skin. Source data are provided as a Source Data file.
