Abstract
Our team has engineered a mobile and cost-efficient diagnostic tool that leverages Electrical Impedance Spectroscopy (EIS) technology to conduct differential assessment of the electrical impedance of skin tissue. Now in its third prototype iteration, the DermaSense apparatus performs non-invasive data collection from the epidermal layer, processing and analyzes the data, and serves as a support tool in dermatological diagnostic decisions. Device development focuses on an array of skin malignancies and relevant precursors conditions, such as actinic keratosis. Subsequent to rigorous evaluations in both controlled lab environments and clinical scenarios, our empirical data suggests that DermaSense holds promise in enhancing the precision of skin condition classification. Crucially, impedance measurements derived from individuals with certain pre existing dermatological ailments appear to be distinguishable from those acquired from healthy patches of skin from the same subject, as well as those from other healthy subjects.
