About

Yuichi Sadamitsu is a pioneer in the field of flexible and curved-surface organic electronics, specializing in the mechanical and thermal engineering of plastic substrates for next-generation sensors and transistors. His most impactful work introduces a novel **thermal molding technique** for fabricating organic thin-film transistor arrays on non-planar surfaces, a breakthrough that overcomes the rigidity of conventional electronics. By analyzing strain distribution in poly(ethylene naphthalate) films during deformation, Sadamitsu demonstrated how to create freely shaped, functional plastic electronics—a foundational contribution to the field, with his 2017 paper garnering 10 citations. Expanding on this, he developed **organic sensor arrays** distributed across curved surfaces with finite Gaussian curvature, applying them to soft robotic fingers for artificial tactile sensing (2019, 3 citations). This work directly addresses the challenge of integrating distributed sensing into compliant, curved robotic skins. Sadamitsu’s research bridges materials science and robotics, enabling devices that can conform to complex geometries while maintaining electronic performance. His achievements are notable for advancing the practical realization of truly flexible, shape-adaptive electronics, with direct implications for soft robotics, wearable tech, and biomedical implants.
