Research & Development of Hydrogel-Based Soft Robots

With the rapidly growing attention to human-robot interfaces, soft robots have aroused a great deal of interest. In contrast to rigid-bodied robots built from metals, ceramics and hard plastics, soft robots have many unique advantages, including compliancy, safety, continuity, and deformability^[1]. Therefore, they can flexibly handle irregular tasks in a simple manner and are desired to be applied in daily life. Hydrogels are promising materials for soft robots due to their outstanding features, including ionic conductivity, biocompatibility, stretchability, and transparency. In addition, hydrogels provide innovative capabilities for soft robots based on their unique responsiveness to stimuli. Thus, hydrogels can be introduced into the field of soft robots, and we call them hydrogel-based soft robots.

Alfa Chemistry is a world-leading company specializing in hydrogel research. With experienced scientists and the most advanced equipment, we have the ability to research and develop hydrogel-based soft robots for different industries.

Manufacturing Techniques of Hydrogel-Based Soft Robots

Traditional manufacturing techniques, such as subtractive techniques like drilling and milling, cannot be used to create hydrogel-based soft robots as these robots have complex shapes with deformable bodies. Therefore, many advanced techniques have been developed for manufacturing hydrogel-based soft robots, including shape deposition manufacturing (SDM), the smart composite microstructure (SCM) process, and 3D multi-material printing.

• SDM is a type of rapid prototyping technique whereby deposition and machining occur cyclically.
• SCM is a process whereby one combines rigid bodies of carbon fiber reinforced polymer with compliant polymer ligaments.
• 3D multi-material printing is an additive manufacturing process that can be used to print a wide range of silicone inks.

Our Scope of Research & Development

For many years, Alfa Chemistry has been interested in the research and development of hydrogel-based soft robots, trying to bring the research results of hydrogel-based soft robots from the laboratory to the market and serve human life. We carry out the research and development of hydrogel-based soft robots, mainly including actuators, sensors, communicators, power sources, and computation circuits.
