<p>Piezotronics hinges on the coupling of strain-induced piezoelectric polarization and charge-carrier transport in noncentrosymmetric semiconductors. This phenomenon significantly influences the design, fabrication, and performance of electronic devices. Furthermore, it facilitates the investigation of the fundamental coupling between piezoelectricity and various other physical processes, including quantum tunneling transport, spin transport, topological properties, and flexoelectronic transport in centrosymmetric semiconductors. This article reviews recent advancements in this field and provides a perspective on the future development of piezotronics in conjunction with related physical processes.</p> Graphical abstract <p></p>
