Instrumentation, electrode choice and challenges in human skin memristor measurement
Abstract:
Recording of the passive electrical properties of human skin is a well-established method in clinical applications and research. By applying a small constant voltage or current to the skin, its conductance can be determined without changing it. If a strong electrical signal is applied, the conductance can change. In fact, such nonlinear effects in skin can be observed and it has been shown that the skin acts like a memristor. These nonlinear properties of human skin are not studied systematically yet and hence represent a new field of research. This paper presents a measurement system that is suitable for doing human skin memristor measurements including hardware, electrode choice and aspects that have to be considered.

The Standard Hydrogen Electrode (SHE) is a widely used reference electrode that maintains zero potential across all temperatures. However, its need for a continuous hydrogen gas supply renders it impractical for everyday use.
An alternative to SHE is the Saturated Calomel Electrode (SCE). This electrode features an...
