We are all familiar with the classic, passive circuit components resistor, capacitor, and inductor. In a 1971 paper, however, Leon Chua argued that there was room for a fourth basic component, which he called memristor, short for memory resistor (Chua, 1971). The memristor is a special kind of resistor in which the resistance is dependent on the net amount of charge having passed through it. Hence, sending a current in one direction... 

He also proposed the circuit symbol shown in Figure 9.29 for the memristor. Looking back, it seems the discovery by Leon Chua did not get as much attention as we today realize it deserved. One reason may be that combining magnetic flux and charge, one could not readily see how this new component could be used in practice. However, using Faraday s law of induction and the definition of electric current in Eq.9.45, it simplifies to ... 

Thus, the memristor can be treated as a nonlinear resistor. The nonlinearity lies in the fact that the memristance is a function both of time and an internal state variable x, that is M(x,t). This state variable is often (but not always) proportional to the electric charge Q. 

Johnsen et al. (2011) showed that the measurements of electro-osmosis in human skin, shown in Figure 8.40, can be closely mimicked by using memristor theory. They also explain the memristive mechanisms involved in electro-osmosis. An introduction to using memristor theory in bioimpedance and bioelectricity is given in Johnsen (2012). The whole concept has also been expanded to include memcapacitors and meminductors (Di Ventra et al., 2009).

Some changes and additions have been made in this edition An electrode is the most important component of any bioimpedance and bioelectric measuring systems. To make the book easier to read, we have dedicated a specific chapter to electrodes. Furthermore, we have extended the chapter on models with a comprehensive tutorial on statistical analysis of bioimpedance data. We have also included the Kelvin probe, memristor theory, and the concept of universality (scaling properties) and we have expanded the survey on impedance analyzers.

The word memristor was first time used by Professor Leon Chua in 1971 [72], In circuit theory, the three basic two-terminal devices the resistor, the capacitor and the inductor are well understood. These three basic elements describe the relation between two of the four fundamental circuit variables current, voltage, charge and flux as shown in fig. 10.There are six possible combinations between these four fundamental circuit variables, out of which five are well defined, but sixth is missing. In 1971, Prof Leon Chua named this missing element as memristor , a short for memory resistor. The memristor has a memristance (M) which provides relationship between charge and flux. 

Many fundamental theorems were proposed by Leon Chua in 1971 and 1976 for describing memristor behaviour but without any physical realization [73]. In 2008, the HP (Hewlett Packard) Lab. has provided a successful physical model implementation of memristors in a nano-scale device by showing basic current-voltage (I-V) characteristics [74]. Chua had proposed the theoretical model of memristor with electric circuits containing at least 15 transistors and other passive...
