“…In IPG, the electrode placement is flexible; that is, the electrode pairs need not cross the heart as ECG electrodes do. For example, IPG electrodes can be placed on the neck 44 , wrist 48 , 49 , arm 7 , leg 50 , feet 51 , or on multiple body sites 45 .…”

“…Leveraging both the PPG and IPG signals, they included changes in the cross-sectional area of blood vessels in a PTT-based model and improved the BP estimation accuracy 96 . It is worth noting that BP can also be estimated using IPG-ECG 51 , IPG-PPG 49 , 97 , IPG-IPG 8 (including IPG + ICG 45 ) combinations, or even single-channel IPG 48 . Several studies have evaluated the performance of PTT-based BP estimates using IPG + ECG and PPG + ECG and reported that the former is superior to the latter in a manner 7 , 44 .…”

Cardiovascular diseases (CVDs) are a leading cause of death worldwide. For early diagnosis, intervention and management of CVDs, it is highly desirable to frequently monitor blood pressure (BP), a vital sign closely related to CVDs, during people’s daily life, including sleep time. Towards this end, wearable and cuffless BP extraction methods have been extensively researched in recent years as part of the mobile healthcare initiative. This review focuses on the enabling technologies for wearable and cuffless BP monitoring platforms, covering both the emerging flexible sensor designs and BP extraction algorithms. Based on the signal type, the sensing devices are classified into electrical, optical, and mechanical sensors, and the state-of-the-art material choices, fabrication methods, and performances of each type of sensor are briefly reviewed. In the model part of the review, contemporary algorithmic BP estimation methods for beat-to-beat BP measurements and continuous BP waveform extraction are introduced. Mainstream approaches, such as pulse transit time-based analytical models and machine learning methods, are compared in terms of their input modalities, features, implementation algorithms, and performances. The review sheds light on the interdisciplinary research opportunities to combine the latest innovations in the sensor and signal processing research fields to achieve a new generation of cuffless BP measurement devices with improved wearability, reliability, and accuracy.

“…However, wet electrodes may cause skin irritation and allergic contact dermatitis [2][3][4], which leads to the difficulty for long-term bioelectricity acquisition. Therefore, capacitive electrodes are often used in wearable bioelectrical acquisition equipment [5][6][7][8][9][10][11][12]. Sun et al defined the capacitive electrode as three types, dry electrodes, insulated electrodes, and non-contact electrodes [6].…”

An Interference Suppression Method for Non-Contact Bioelectric Acquisition

et al. 2020

For non-contact bioelectrical acquisition, a new interference suppression method, named ‘noise neutralization method’, is proposed in this paper. Compared with the traditional capacitive driven-right-leg method, the proposed method is characterized with that there is an optimal gain to achieve the minimum interference output whatever for the electrode interface impedance mismatch caused by body motion and is more effective for smaller reference electrode areas. The performance of traditional capacitive driven-right-leg method is analyzed and the difficulty to suppress interference in the case of the interface impedance mismatch is pointed out. Therefore, a noise neutralization method is proposed by applying the reference electrode and a 50 Hz band-pass filter to obtain the interference of the human body and adapting the gains to neutralize the interference inputs of two acquisition electrodes and achieve the minimum interference output. The performance of the proposed method is theoretically analyzed and verified by the experiment results, which shows that the proposed method has similar performance to that of the traditional capacitive driven-right-leg method with electrode interface impedance match, while has better interference suppression ability with electrode interface impedance mismatch caused by body motion. It is suggested that the proposed method can be preferred in the case of limited reference electrode area or interface impedance mismatch.
