Tohoku University Technology: Self-healing mechanism and soft robot: T20-030
Able to effectively self-repair in any environment, even in the case of major damage, regardless of external factor
In recent years, soft robot that can flexibly transform according to their environment and adapt to various environments has been developed. However, due to its flexible structure, soft robot can be damaged when they come into contact with sharp object, resulting in the loss of functionality such as mobility and deformability. Material such as polymer has been developed to self-repair damaged part. However, it can not repair itself in case of major damage. This invention is able to provide a self-healing mechanism and a soft robot that can self-repair in any environment, regardless of external factor, even in case of major damage. This invention has a curing means consisting of 2 tubes containing 2 different liquids that gel or harden when mixed, which are wrapped around each others in spiral. The soft robot of this invention has this hardening means stretched along the deformed and flexible area. When the soft robot is damaged by contact with sharp object, the 2 tubes are also damaged and each liquid gels or hardens, allowing the robot to repair itself.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
