    The aim of this project is to create a scanner that measures electrical impedance on the skin (Magnitude + Phase shift). The hardware that i am going to use is: USB-2020 DAQ, Universal Screw Terminal (37-pin), Arduino, SparkFun MiniGen signal generator. The software that i am going to use is: Labview 2019 SP1 I need a freelancer to help me build my acquisitioning circuit and develop the LabView software to operate it. The logic behind the circuit is, we apply some voltage/current on the skin and measure the impedance of that area as a response. We then do the necessary calculations and print the results on the screen in Graph form, Nyquist plots and (if possible) some type of spectrogram. Hardware should be placed in a black box and operated exclusively through software.
