A novel, non-invasive dermatological diagnostic instrument for skin resistance scanning (DermaSense)

Initial physical examination in dermatology is often based on visual inspection and clinical experience, supported by technologically simple devices such as the dermatoscope. While such devices can be rather effective in trained hands, they cannot provide objective measurement data and error margins. We propose a specific adaptation of electrical impedance tomography scanning, a technology which has proven its value in other medical disciplines, as a support tool for dermatological physical examination and -eventually- diagnosis. A proof of concept prototype of the DermaSense device has been constructed and is currently being evaluated, while clinical pilot measurements related to melanoma are being planned.
