Hydroxy fluorosilicone oil has recently made breakthrough progress in the fields of flexible wearable electronics and biomedical sensing. With its unique molecular designability, exceptional surface activity, and excellent biocompatibility, this material is evolving from a traditional textile coating agent into a core interfacial material for constructing high-precision, long-life flexible sensors, opening up new technological pathways for real-time health monitoring, smart healthcare, and metaverse human-computer interaction.

Research shows that through specific functionalization of hydroxy fluorosilicone oil molecules, it can be endowed with sensitive responses to specific biological signals or excellent ionic conductivity while maintaining low surface tension (~22 mN/m) and high flexibility. As a dielectric layer material for flexible sensors, its interfacial performance is exceptionally stable, with dielectric loss below 0.005, enabling the sensitivity of fabricated capacitive pressure sensors to reach 500 kPa⁻¹ and maintaining signal stability under 90% tensile strain. After 100,000 bending cycle tests, its electrical performance degradation is less than 5%.

In the health monitoring field, electronic skin constructed based on hydroxy fluorosilicone oil interface engineering has achieved breakthroughs. Its ultra-thin encapsulation layer (<10 microns) not only imparts a skin-like soft touch and high breathability to the device but also effectively isolates interference from sweat and the external environment, making the monitoring stability of biological signals such as dynamic electrocardiogram (ECG), electrodermal activity (EDA), and blood oxygen saturation (SpO₂) comparable to that of medical-grade equipment. The first batch of continuous glucose monitoring (CGM) patches applying this technology have achieved accurate monitoring for up to 14 days in clinical trials, with their biocompatible coating significantly reducing skin inflammatory reactions.

With the rise of the metaverse and virtual reality technologies, hydroxy fluorosilicone oil demonstrates immense potential in enhancing the realism of human-computer interaction. Multi-modal haptic feedback gloves constructed based on it can accurately simulate different textures from silk gliding to sandpaper friction, with tactile resolution reaching 0.1 mm. Furthermore, its derived self-healing ionogel materials bring near-real tactile perception and temperature sensing functions to next-generation bionic prosthetics.

Industry analysts point out that this technological leap of hydroxy fluorosilicone oil marks its strategic transition from a “passive protection” material to a core material for “active sensing and interaction.” It will strongly drive the convergent innovation of consumer electronics, digital healthcare, and interactive entertainment industries, and is expected to foster a hundred-billion-yuan flexible electronics market oriented toward personalized health and immersive experiences within the next five years.
