The Simulation Analysis of Bioimpedance Variations for Skin Lesion

Abstract

Excess sun exposure could cause skin lesion or even worse skin cancer Early treatment helps to reduce mortality Recently studies shows the correlation between bioimpedance phase angle and health status where vastly focus on total body measurement Therefore bioimpedance phase angle is adopted in skin lesion assessment with simulation By simulating process of actual bioimpedance measurement phase angle variation in different skin thickness electrical parameter lesion extension is evaluated Finally we try to introduce a proposal in measuring bioimpedance phase of skin lesion The result shows a better phase resolution for low-frequency measurement Low-frequency measurement is beneficial for estimating skin thickness and lesion extension and provides good tolerance of phase error in lesion-electrode misalignment
