Kirigami-Inspired Robotic Grippers: Merging Power and Precision
Introduction:
Researchers from North Carolina State University have developed innovative robotic grippers inspired by the Japanese art of paper cutting, known as kirigami. These grippers have the ability to fold clothes, grasp water droplets and microfibers, lift objects 16,000 times their own weight, and even turn the pages of a book. With a payload-to-weight ratio of 16,000, these grippers outperform previous models and offer a balance of strength, precision, and gentleness. The design of the grippers allows for a wide range of potential applications, including prosthetics, minimally invasive surgery, deep-sea exploration, food processing, and electronics manufacturing.

Researchers from North Carolina State (NC State) University have developed innovative robotic grippers inspired by the Japanese art of kirigami. These grippers have the ability to fold clothes, grasp water droplets and ultrathin microfibers, lift weights 16,000 times their own, and even turn the pages of a book. The team believes that this design has a wide range of applications in areas such as prosthetics, minimally invasive surgery, and deep-sea exploration.
The Challenge: Developing a Gripper that Balances Strength, Precision, and Gentleness
Creating a soft gripper that can handle ultrasoft, ultrathin, and heavy objects is a difficult task due to the tradeoffs between strength, precision, and gentleness. However, the researchers from NC State University have overcome this challenge by achieving an excellent balance of these characteristics in their design.
The Role of Kirigami in Creating Innovative Grippers
To achieve the desired balance, the researchers drew inspiration from kirigami, a Japanese art form similar to origami where two-dimensional paper is folded and cut to create three-dimensional shapes. By leveraging the principles of kirigami, the team developed grippers with unique advantages.
Impressive Payload-to-Weight Ratio Sets a New Record
Traditional measurements of robotic gripper strength focus on the payload-to-weight ratio. The researchers’ grippers, weighing only 0.4 grams, can lift up to 6.4 kilograms (14.1 pounds), resulting in a payload-to-weight ratio of approximately 16,000. This is 2.5 times higher than the previous record of 6,400. Furthermore, the grippers demonstrate gentleness and precision, making them suitable for a wide range of applications.
Design Over Material: Potential for Biodegradable Grippers
According to the researchers, the grippers’ characteristics are primarily determined by their design rather than the materials used. They suggest that the grippers could be fabricated from biodegradable materials, such as sturdy plant leaves. This feature makes them particularly useful for applications where the grippers are used temporarily, such as handling food or biomedical materials.
Enhancing Prosthetic Functionality
In proof-of-concept testing, the researchers integrated the grippers with a muscle-controlled (myoelectric) prosthetic hand. The grippers successfully performed tasks like turning the pages of a book and picking grapes from a vine. Although the grippers cannot replace all the functions of existing prosthetic hands, they can complement them. Additionally, they can make use of the existing motors in robotic prosthetics, eliminating the need for replacements or augmentation.
Potential Applications in Various Industries
The researchers believe that their gripper design has widespread potential applications across fields such as robotic prosthetics, food processing, pharmaceutical manufacturing, and electronics manufacturing. They are eager to collaborate with industry partners to explore these opportunities further.
Conclusion
In a groundbreaking development, researchers from NC State University have designed robotic grippers inspired by the art of kirigami. These grippers excel in strength, precision, and gentleness, thanks to their innovative design. With a record-breaking payload-to-weight ratio and the potential for biodegradability, these grippers have the ability to revolutionize industries ranging from prosthetics to electronics manufacturing.
