Applications and Future Trends of Silicone Materials in AI Smart Devices

With the rapid development of AI smart devices—such as wearables, flexible electronics, and robots—the requirements for materials have become increasingly stringent. Key performance indicators now include lightweight design, durability, biocompatibility, efficient heat dissipation, and adaptability to complex deformation. Silicone materials, owing to their unique properties, play a critical role in AI devices and are evolving toward higher performance, functional diversification, and environmental sustainability.

Application Areas

Silicone materials are widely used across several core domains of AI devices:

Flexible Electronics and Wearables
Polydimethylsiloxane (PDMS), valued for its flexibility and biocompatibility, is used as a substrate for flexible sensors, electronic skin, and stretchable circuits. Silicone resin coatings protect electronic components from moisture and oxidation, extending the lifespan of devices such as smartwatches. Thermally conductive silicone pastes and silicone pads are used between AI chips (GPUs, CPUs) and cooling modules to address thermal management challenges in high-performance devices.

Robotics and Biomimetic Structures
Silicone rubber mimics the texture and elasticity of human skin and is used for robot surface coverings and joint seals, enhancing human–machine interaction safety. In robot joints and moving parts, silicone rubber serves as a damping pad or seal, resisting vibrations and dust ingress.

Sensors and Actuators
PDMS and other silicone rubbers can be fabricated into microstructured films for detecting pressure, strain, or tactile signals, such as pulse sensors in AI medical applications. Electrically active silicone rubbers, doped with conductive fillers, deform under electric fields and are applied in micro-robots and flexible actuators.

Optics and Displays
Organic silicone optical adhesives offer over 90% light transmittance and excellent yellowing resistance, widely used for bonding and protecting flexible displays, such as foldable smartphones. Silicone resin encapsulants enhance LED heat resistance and luminous efficiency, applied in AI lighting and display systems.

Energy and Battery Systems
Silicone rubber is used as sealing gaskets in lithium-ion batteries to prevent electrolyte leakage and improve battery safety due to its heat resistance. Silicone resin films are applied in proton exchange membrane fuel cells (PEMFCs) to enhance proton conductivity and chemical resistance.

Development Trends

Silicone materials are evolving in several directions to better meet AI device requirements:

Modified Silicones
Incorporating nanomaterials such as graphene, carbon nanotubes, or boron nitride improves thermal, electrical, and mechanical properties. For example, boron nitride/silicone rubber composites can achieve thermal conductivities of 5–10 W/(m·K). Additionally, introducing fluorine or phenyl groups enhances oil resistance, radiation resistance, and optical properties, as seen in fluorosilicone for aerospace seals.

Bio-based Silicones
Synthesis of silane coupling agents or silicone rubbers from biomass, such as straw or lignin, reduces dependence on fossil resources and aligns with sustainable development trends.

3D Printing and Customization
Development of light-curable or heat-curable silicone inks combined with 3D printing enables rapid fabrication of complex structures, such as flexible sensor arrays or microfluidic channels, meeting the personalized needs of AI devices.

Self-Healing and Smart Response
Silicone materials designed with dynamic chemical bonds, such as hydrogen or metal coordination bonds, can self-repair scratches or deform in response to temperature or pH changes, improving device durability and adaptability.

Environmental Sustainability and Recycling
By introducing ester or urea linkages, biodegradable silicones can be developed. Chemical recycling methods such as hydrolysis or pyrolysis enable the reuse of discarded silicone rubbers, reducing environmental pollution from electronic waste.

Conclusion

In summary, silicone materials not only form the foundational support for AI smart devices but also continuously expand their application scope through technological innovation. Ongoing advances in performance, functionality, and sustainability provide critical material solutions for the future development of smarter, more durable, and environmentally friendly devices.
