The possibility of ECG recording in patients with burns using capacitive electrodes was not proved, and there are no models of the electrode contact with a patient’s body while rehabilitation means are used. In this paper, the model of the contact between capacitive electrodes and the skin was modified and the circuit model of the contact: skin – bandages (saline solution) – film – active capacitive electrode, was described. The influence of the parameters of a capacitive electrode on the amplitude-frequency characteristics (AFC) of the contact of an electrode with skin was assessed. It was found that contact capacitance is crucial to obtain a high-quality ECG signal. The parameters of the impedance of bandages, saline solution, a dielectric film were calculated, and their effect on the AFC was studied. Bas...

Описано новий напрям розвитку неінвазивних систем реєстрації-застосування електроміографії високого розрізнення (ЕМГ ВР). До проблем неінвазивних систем реєстрації поверхневої ЕМГ ВР віднесено складність отримання якісного сигналу без рухових артефактів. Запропоновано можливі напрями використання систем ЕМГ ВР для реабілітації, оптимізації розміщення електродів та зменшення їх кількості в процесі встановлення протезів людям з ампутаціями верхніх кінцівок. Визначено можливість використання динамічного прогнозування рухів протезу в реальному часі на основі системи ЕМГ ВР для покращення інтуїтивної взаємодії людини з протезом. Бібл. 23, рис. 8.
