Abstract
A system for bioimpedance analysis of a biological tissue includes a tissue inspector and an impedance calculator. The tissue inspector includes an inspecting circuit for receiving a test signal, a plurality of electrode sets respectively corresponding with a plurality of test parts, and a multiplexer operable to couple a selected electrode set at a detected test part to the inspecting circuit to detect a signal response resulting from the test signal. The impedance calculator is operable to compute impedance information corresponding to the detected test part based on the test signal and the detected signal response.
