This paper presents a wearable electrophysiological interface with enhanced immunity to\nmotion artifacts. Anti-artifact schemes, including a patch-type modular structure and real-time\nautomatic level adjustment, are proposed and verified in two wireless system prototypes of\na patch-type electrocardiogram (ECG) module and an electromyogram (EMG)-based robot-hand\ncontroller. Their common ExG readout integrated circuit (ROIC), which is reconfigurable for multiple\nphysiological interfaces, is designed and fabricated in a 0.18 �¼m CMOS process. Moreover, analog\npre-processing structures based on envelope detection are integrated with one another to mitigate\nsignal processing burdens in the digital domain effectively.
