MOTION ARTIFACTS LESS ELECTRODE FOR BIO-POTENTIAL MEASUREMENTS AND ELECTRICAL STIMULATION, AND MOTION ARTIFACTS LESS SKIN SURFACE ATTACHABLE SENSOR NODES AND CABLE SYSTEM FOR PHYSIOLOGICAL INFORMATION MEASUREMENT AND ELECTRICAL STIMULATION

摘要

Motion artifacts less electrode for bio-potential measurements and electrical stimulation is discussed under the present invention. Three different arrangements of the electrode are introduced. Further the electrode embodiments are generalized for reducing motion artifacts of any skin contact senor or an actuator embodiment. In addition a piggy backed daisy chained sensor nodes or actuator nodes cabling system is introduced to minimize the motion artifacts further. A PPG sensor is constructed according to the generalized sensor embodiment and this PPG sensor is used for constructing an ear wearable heart rate monitoring unit. Moreover an ear wearable EEG monitoring system based on piggy backed daisy chained sensor or actuator nodes and caballing arrangement is illustrated.
