We report a 2-μm-thick ultraflexible organic differential amplifier capable of processing physiological signals with high signal integrity. Circuit compensation technique enables to suppress the electric mismatch among transistors and improves a common-mode noise attenuation factor. Using our flexible amplifier, we monitor electrocardiogram signals with a signal-to-noise ratio of 34 dB.
