Fig. 14From: Traumatic brain injury neuroelectrochemical monitoring: behind-the-ear micro-instrument and cloud applicationPotassium measurements. The generated logarithmic working curve for potassium measurements of concentrations between 2.7 mM to 30 mM in a physiological buffer. The curve shows an R2 of 0.918. n= 2000 samples for each concentration point. Error bars show mean and standard deviationBack to article page
