Electrocardiac Signals (IMAGE) Osaka University Caption Electrocardiac signals obtained using flexible organic differential amplifier: (A) Conventional single-ended amplifier (B) Differential amplifier developed in this study (C) Electrocardiac signals obtained from a walking subject. In the electrocardiac signals obtained using a conventional single-ended amplifier, large noise caused by walking is included in the waveform. In contrast, such noise is removed from the waveform obtained using the developed flexible organic differential amplifier.
