China3D printingNet, January 31, researchers at Cornell University in Ithaca, New York developed a3D printingThe soft robot muscles, which can control its internal temperature by wicking perspiration.
Using hydrogel-based composite resins and stereolithography (SLA), a soft finger-like actuator that can retain water and respond to temperature is produced. According to Robert Shepherd, associate professor of mechanical and aerospace engineering, this biologically-inspired form of thermal management can allow unfettered robots to run for longer periods of time.
TJ said: “Sweat uses the evaporated water to quickly dissipate heat and can cool to the ambient temperature.” Wallin is a research scientist at Facebook Reality Labs and the first author of the study. The paper was published in “Science Robots.” . “Usually, biology provides us engineers with excellent guidance.”

“Sweaty”
As Professor Shepard, who is in charge of the project, said, because exothermic engines tend to overheat, one of the obstacles to making durable, agile, and flexible robots is to control their internal temperature. In addition, synthetic materials used in soft robots retain heat, while metals quickly dissipate heat. There, the researchers sought to create a natural cooling system that would not add weight or limit the design of soft robots.
Customized hydrogel composite resins are used to additively manufacture finger fluid elastomer actuators that have holes that automatically open and close in response to thermal fluctuations. The hole expands at elevated temperature, releasing water, and cooling rate is more than 600% faster than similar non-sweat devices.
Wallin said: “The best part of this synthesis strategy is that the thermal regulation performance depends on the material itself. We don’t need sensors or other components to control the sweat rate. When the local temperature rises above the transition temperature, the pores will open and closure.”

Self-cooling robot
After several grip tests, the researchers found that automatic sweating prevented the robot from overheating, but the surface of the robot was indeed slippery. Therefore, the texture of the hydrogel will be modified. In addition, the robot’s ability to secrete fluids may also lead to methods for absorbing nutrients, catalyzing reactions, and removing pollutants.
China3D printingNet comment: We believe that the future of making these materials and robots with more biological similarities will depend on the composition of the materials. This raises a point of view on the importance of interdisciplinary research in this field. In this field, In fact, no one can provide all the answers.
