New breakthrough in artificial muscle smart materials

Smart materials are a new class of new materials that can actively respond to external stimuli. They have multiple functions such as self-driving, self-monitoring, and self-healing. They are widely used in artificial intelligence, intelligent manufacturing, biomedicine, robotics and other fields.application prospects.

Our scientific research team, together with domestic and foreign scientific research partners, has made a major breakthrough in the field of artificial muscles, completely solving the problem of capacitance dependence of the driving performance of artificial muscles, and providing a new theoretical basis for the further development of artificial muscles.It provides a new theoretical basis for the subsequent design of high-performance drivers with non-toxic, low driving voltage and high energy density.This important discovery and breakthrough provides a broader prospect for the subsequent application of artificial muscles.

The study found that through the functionalization strategy of polyelectrolyte, the "bipolar" driving of artificial muscle intelligent materials can be converted into "unipolar" driving, which can improve its performance such as work efficiency and energy density, and solve the capacitance of traditional artificial muscle driving performance.Dependency issues.At the same time, this new material has the characteristics of non-toxicity, high driving frequency, low driving voltage, high specific energy, high driving strain and high energy density.

The new artificial muscle has better performance, simpler structure and better biocompatibility. In the future, if this achievement is applied to the drive of bionic aircraft, the aircraft will be lighter, and will fly higher, farther,Longer; if applied to the biological field, its non-toxic properties will give medical robots better biocompatibility.

It is understood that this upgraded version of artificial muscle intelligence material has huge applications in the fields of space deployment structures, bionic flapping aircraft, deformable aircraft, underwater robots, flexible robots, wearable exoskeletons, medical robots, etc.potential.

The research results, titled "Unipolar Stroke, Electroosmotic Pump Carbon Nanotube Yarn Muscle", were published in the academic journal "Science".Hanyang University, University of Wollongong, Australia and other units cooperated to complete.
