The aim of this chapter is to discuss to what extent one of the formulations (interpretations) of the quantum theory, i.e. Bohmian mechanics, which provides a singular tool to predict and explain the behavior of novel electron devices. It describes how Bohmian trajectories can help to solve them. The chapter summarizes postulates, equations and the most important features of Bohmian mechanics regarding the description of electron transport including the measurement process and many-body correlations. It also describes how Bohmian mechanics can be applied to simulate electron transport. The main pieces required to build up a trajectory-based electronic device simulator are discussed. The focus is on the electric current, and the chapter provides a practical method to evaluate the electrical current. Finally, a detailed description of the equations required to evaluate DC, AC, transients and any moment of the current is presented.
