About

Toru Katsumata is a leading materials scientist whose work sits at the intersection of polymer chemistry and soft electronics, with a particular focus on self-healing elastomers. His most celebrated contribution is the development of a tough, water-insensitive self-healing elastomer for robust electronic skin, published in 2018 and now cited over 1,100 times. This breakthrough addressed a critical challenge in the field: creating materials that are not only soft and stretchable but also possess high fracture energy, allowing them to resist crack propagation and maintain functionality after damage. Katsumata’s work has been instrumental in advancing the durability and practicality of e-skin for applications in wearable sensors, prosthetics, and human-machine interfaces. His research is distinguished by its ability to combine mechanical robustness with autonomous healing, even in humid or wet conditions—a feat that had previously eluded the field. By tackling the trade-off between softness and toughness, Katsumata has helped pave the way for next-generation electronic materials that can withstand real-world wear and tear, making him a key figure in the development of resilient, self-repairing soft electronics.
