    Impedance measurements that involve the human body are affected by the capacitance between the body and earth ground. This paper describes a low-cost method to estimate that capacitance that can be applied to impedance ...
  • Effects of stray capacitance to ground in bipolar material impedance measurements based on direct-contact electrodes 

    Aliau Bonet, Carles; Pallàs Areny, Ramon (2014-10-01)
    Article
    Restricted access - publisher's policy
    Bipolar material impedance measurements are easier to implement than tetrapolar measurements but are more affected by electrode impedance. This effect can be reduced by measuring at a high-enough frequency albeit with the ...
