Area of Science:

• Soft Matter Physics
• Materials Science
• Intelligent Systems

Background:

• Designing multi-stimulus responsive soft materials with integrated functionalities for intelligent systems is complex.
• Existing materials often lack the ability to perceive and visualize diverse stimuli effectively.

Purpose of the Study:

• To demonstrate an intelligent soft architecture for sensing and display.
• To utilize magnetized liquid metal droplets as a core component for stimulus perception and information visualization.

Main Methods:

• Dispersing magnetized liquid metal droplets within a highly stretchable elastomer network.
• Utilizing the controllable solidification of supercooled liquid metal droplets to release thermal energy.
• Employing thermal and thermochromic imaging to visualize stimuli and material responses.

Main Results:

• The developed architecture successfully perceived various contact (mechanical pressing, stretching, torsion) and noncontact (magnetic field) stimuli.
• Programmable visualization and display of information-encoded stimuli were achieved.
• Dynamic phase transition and stress evolution processes were visualized through thermal imaging.

Conclusions:

• The liquid metal-elastomer architecture provides a versatile platform for advanced soft intelligent systems.
• This approach enables the creation of soft intelligent sensing, display, and information encryption systems.
• The material demonstrates potential for future applications in responsive and interactive technologies.
