In cutting-edge fields such as foldable smartphones, smart wearables, and electronic skins, silicone rubber is becoming the "invisible skeleton" of flexible electronic devices. Its unique molecular flexibility and chemical inertness enable it to protect precision circuits while adapting to repeated bending deformations, with a folding life of over 200000 times. The flagship phone of a certain brand uses silicone rubber as the hinge buffer layer, which maintains a bending radius of 1.5mm within the temperature range of -40 ℃ to 80 ℃ without failure.

The optimization of the dielectric properties of silicone rubber provides the possibility for flexible electronic integration. By doping nano alumina or barium titanate, its dielectric constant can be increased from 2.5 to 8.0, meeting the requirements of high-density capacitors. A silicone rubber based supercapacitor developed by a research institution has an energy density of 15 Wh/kg, can bend up to 90 ° without sacrificing performance, and is suitable for wearable power supply modules.

In the field of bioelectronics, the biocompatibility of silicone rubber has given rise to revolutionary products. The implantable brain computer interface uses ultra soft silicone rubber (Shore A5 degree) as the packaging material, with a Young's modulus close to human tissue, significantly reducing immune rejection reactions. The epidermal electronic patch developed by a certain enterprise integrates a sensor array based on silicone rubber, which can monitor body temperature and heart rate in real time, with an adhesion force of up to 30 kPa and no skin irritation.

The integration of silicone rubber and emerging technologies is still accelerating. 3D printing silicone rubber technology has broken through the limitations of traditional molds and can manufacture microfluidic chips and complex structured antennas with a line width resolution of up to 50 μ m. Combined with UV curing technology, the printing speed has been increased to 100mm per hour, meeting the needs of small batch customization. From consumer electronics to healthcare, silicone rubber is reconstructing the form and functional boundaries of future electronic products with its flexible, intelligent, and customizable characteristics.
