This study presents SmartProbe, an electrical bioimpedance (EBI) sensing system based on a concentric needle electrode (CNE). The system allows the use commercial CNEs for accurate EBI measurement, and was specially developed for in-vivo real-time cancer detection. Considering the uncertainties in EBI measurements due to the CNE manufacturing...
