We developed a portable, affordable, non-invasive prototype medical instrument which employs the principles of electrical impedance spectroscopy (EIS) to characterize skin tissue by differentially measuring its electrical impedance. Currently in its 3rd generation prototype, the Dermasense device performs non-invasive data acquisition from the skin surface, analyzes the data and functions as a dermatological medical decision support system. The design and development of the device focuses on various forms of skin cancer as well as pre-cancerous tissue lesions (such as actinic keratosis). Following experimentation in both laboratory and clinical settings, our findings reveal that the device has the potential to contribute in the improvement of classification and thus identification of skin conditions. Measurements obtained from patients already diagnosed with dermatological conditions were shown to deviate from those obtained from healthy individuals.
