The invention relates to a measuring device for electrical characteristic distribution of a human body surface, a data terminal and a method. The measuring device comprises an excitation acquisition module, a signal processing module and a transmission module, wherein the excitation acquisition module is used for producing excitation signals for exciting a tested part of the human body surface, transmitting the excitation signals to the tested part, and acquiring response signals, under the effect of the excitation signals, of the tested part; the signal processing module is used for processing the response signals and the excitation signals about amplitudes and phases, carrying out coding on amplitude information and phase information obtained after the processing, and outputting coding results, wherein the coding results are impedance data of the skin of the human body surface; and the transmission module is used for sending out the coding results. According to the invention, the impedance data of the human body surface, including phase information and amplitude information, can be acquired, can be taken as other electrical characteristic values of the skin and tissue, and avoids system complexity and high cost caused by collecting various parameters.
