Small-molecule organic semiconductors feature weak intermolecular bonds and excellent mechanical flexibility, making them highly attractive for film-like devices that can be installed on curved surfaces or used in biomedical measurements involving dynamic shape changes. Recently, it has become clear that the flexibility and electrical conductivity of organic semiconductors are strongly correlated. This has led to the discovery of their utility not merely as "shape-morphing semiconductors," but as "semiconductors that utilize shape deformation." In this presentation, we will discuss the mechanism of converting shape changes into variations in electrical conductivity using high-mobility organic semiconductor single crystals, in which microscopic intermolecular interactions are directly reflected in macroscopic electrical conductivity. Additionally, practical applications of high-sensitivity strain and vibration sensors will be presented.
