Peter, thank you again for your reply. I'll try to resume what I’m trying to reach.
The outer layer of skin, epidermis, has around 150 micrometers. Furthermore, skin has another layer, the internal one, named dermis, which has a thickness of 1.7mm. When we apply presure for a long periods of time the capilars can’t drive nutrients to the skin cells, which results in their dead. When a cell is alive her membrane can be moduled as a capacitor because they are like barriers to the charge flow and consequently they mantain a potencial difference between intra and external celular medium. So there are both a capacitance and resistance related with external fluid flow that can be easly related with impedance that can be measured at the surface of our tissue. If the cells die, the impedance changes, because membranes loses its integrity. It would be amazing if i could simulate that!
