ECG Measurement Using Capacitive Coupling Electrodes for Man-Machine Emotional Communication

Development of a Novel Noncontact ECG Electrode by MEMS Fabrication Process

“…Since no direct contact is necessary, capacitive sensors can be concealed in everyday objects such as clothing, stretchers [6][7][8], examining tables, beds [9][10][11], or other furniture [12][13][14][15][16] for long term unobtrusive monitoring of vitals or can be employed in vehicles for assisted driving [17].…”

Flexible noncontact electrodes for comfortable monitoring of physiological signals

“…11,13,17,21 This study further extended these noncontact electrode technologies by introducing flexible FPC electrode with the improved analog signal conditioning. 26,31 With the active shielding and bootstrap technologies, EEG signals could be successively measured with the electrode placed over the hair without any conductive gels (Figures 7 and 8), making the proposed electrode a great candidate for easy, comfort, and zero preparation EEG measurement for computer brain interface, sleep monitoring, and other wearable health applications. Active shielding technology 30 was used along the signal path to prevent different interferences from degrading the useful signal.…”

“…[25][26][27][28] The skin and the electrode plate correspond to the two sensing surfaces of the capacitor, whereas the clothing corresponds to the insulation In the current study, the noncontact flexible electrode and the data acquisition circuit were shown in Figure 1, which can be bent along the curvature of the skin to get a higher quality signal.

“…Fundamentally, the noncontact electrodes use capacitive coupling principle for signal acquisition. [25][26][27][28] The skin and the electrode plate correspond to the two sensing surfaces of the capacitor, whereas the clothing corresponds to the insulation can be viewed at wileyonlinelibrary.com] medium in the middle of the capacitor. The output of the physiological signals is the subtraction of recordings from the two electrodes that are placed at different positions on the skin surface.…”

Human machine interface: robotizing the instinctive living

“…In this method, sensors are placed on the chest of the human/animal body to receive the heart activity, which is then measured by external equipment. 19 In this technique, heart beat rhythm is estimated through ECG electrodes. The main disadvantage of this technique is that its operation is restricted to a single purpose i.e.…”
