Bioelectrical Impedance Analysis (BIA) is a widely adopted, non‐invasive technique used to estimate body composition by applying a low-level alternating electrical current through the body. This ...

(A) Water molecules exhibit charge offsets in an alternating electric field. (B) Brain lesions such as bleeding foci, cerebral edema, and infarcts alter electrical impedance, which can be detected via ...

Microneedle electrodes can penetrate beneath the skin, allowing for more accurate bioelectrical signal acquisition (such as EEG, ECG, and EMG) from outside the body. Research into their materials has ...
