    Hello everyone.

    Can you help me how to build a circuit which can measure Bioelectrical Impedance and Phase angle in 50KHZ?

    Jsut like this prodcut below:

    I wonder how to separate resistance and reactance.
    Moreover, How dose the Phase Degree can be measured when a 800uA current through our body.

    Dose anyone know the technology about it?
    Thanks!
