The self-maintenance system breaks through the hygiene bottleneck. The application of nano-photocatalytic coating enables the
torso sex doll to have self-cleaning ability and decompose organic residues under visible light. High-end models are equipped with microfluidic channels, which can automatically circulate to 3mm deep under the skin after injecting disinfectant gel. The antibacterial solution of some
new sex dolls can be called science fiction - bacteriophage microcapsules are embedded in the silicone matrix, and specific viruses are released when pathogenic bacteria are detected to exceed the standard, achieving biological-level cleaning. Microbiological testing shows that this technology keeps the total colony count at <10CFU/cm², meeting the standards for surgical instruments.
