Abstract: The field of piezoresistance has mainly advanced through experimental research; however, the improved accuracy of simulations and the emergence of new materials have increased the importance of simulations in this field. This review discusses the methods and current topics related to simulations of piezoresistive devices. Advancing simulation modeling will facilitate the computer-aided design of piezoresistive devices, and this review introduces the means of establishing these models by discussing the current studies on simulations and calculations in this field. Two simulation methods currently exist namely, device simulations and first-principles theoretical analysis. This review focuses on numerical simulation approaches for modeling of the piezoresistive effect using the multiphysics simulations of the mechanical and electrical behaviors of piezoresistive materials.
