“…Different types of bioimpedance measurement techniques have been developed and used extensively to evaluate the structure, content, and function of biological tissues and organs. 17,30,31 For example, electrical impedance tomography (EIT) is an imaging modality that can visualize internal organs, such as lung, by mapping electrical properties of the patient's body in a noninvasive and radiation-free manner. 33 Similarly, the percentages of body fat and muscle mass can be estimated indirectly by measuring the bioimpedance across a human body.…”

Opto-electromechanical quantification of epithelial barrier function in injured and healthy airway tissues

The airway epithelium lining the luminal surface of the respiratory tract creates a protective barrier that ensures maintenance of tissue homeostasis and prevention of respiratory diseases. The airway epithelium, unfortunately, is frequently injured by inhaled toxic materials, trauma, or medical procedures. Substantial or repeated airway epithelial injury can lead to dysregulated intrinsic repair pathways and aberrant tissue remodeling that can lead to dysfunctional airway epithelium. While disruption in the epithelial integrity is directly linked to degraded epithelial barrier function, the correlation between the structure and function of the airway epithelium remains elusive. In this study, we quantified the impact of acutely induced airway epithelium injury on disruption of the epithelial barrier functions. By monitoring alternation of the flow motions and tissue bioimpedance at local injury site, degradation of the epithelial functions, including mucociliary clearance and tight/adherens junction formation, were accurately determined with a high spatiotemporal resolution. Computational models that can simulate and predict the disruption of the mucociliary flow and airway tissue bioimpedance have been generated to assist interpretation of the experimental results. Collectively, findings of this study advance our knowledge of the structure–function relationships of the airway epithelium that can promote development of efficient and accurate diagnosis of airway tissue injury.

“…Baseline noise is one of the most critical parameters in electro-physiological measurements, in particular in applications where very low signals (in the μV range) are anticipated. Commonly, noise values are predicted from the electrode-skin impedance which is used to quantify the quality of the interface and to predict contact quality (Grimnes 1983, Huigen et al 2002, Kim et al 2014, Krachunov and Casson 2016, Roy et al 2020, Pi ̂slaru-Dănescu et al 2022, Xie et al 2022. In wet electrodes, the conducting gel reduces the skin-electrode impedance and ensures low baseline noise levels (Li et al 2017).…”

Objective. To explore noise characteristics and the effect physiological activity has on the link between impedance and noise. Approach. Dry-printed electrodes are emerging as a new and exciting technology for skin electro-physiology. Such electrode arrays offer many advantages including user convenience, quick placement, and high resolution. Here we analyze extensive electro-physiological data recorded from the arm and the face to study and quantify the noise of dry electrodes, and to characterize the link between noise and impedance. In particular, we studied the effect of the physiological state of the subject (e.g. rapid eye movement sleep) on noise. Main results. We show that baseline noise values extracted from dry electrodes in the arm are in agreement with the Nyquist equation. In the face, on the other hand, the measured noise values were higher than the values predicted by the Nyquist equation. In addition, we studied how different electrode properties affect performances, including electrode size, shape, and material properties. Significance. Altogether, the results presented here provide a basis for understanding dry electrode performances and substantiate their great potential in electro-physiological investigations.
