Dance Humanoid Robots With Large Limb Motion

Conventional bionic silicone applied to skin of high-freedom dynamic robots has four obvious drawbacks. First, limited stretch capacity leads to tearing. Ordinary silicone has low breaking elongation and cracks easily under large joint torsion and stretching. Second, skin whitening and texture damage after stretching. Even without full tearing, stretched area turns white and replicated skin pores and fine lines break, destroying realistic appearance. Third, fast aging and embrittlement after repeated large deformation. Mechanical performance declines quickly after multiple stretch cycles and skin becomes brittle with shortened service life. Fourth, high maintenance and replacement cost. Once dynamic robot skin tears, full disassembly and replacement are required, causing long downtime and high project cost.

Such dynamic bionic skin is widely used for dance performance humanoid robots, full-body multi-degree bionic prototypes and large-joint rehabilitation bionic equipment. These projects demand high dynamic deformation performance of skin, and traditional static bionic skin materials cannot meet requirements. The market is in urgent need of dedicated bionic skin silicone combining high stretch performance and realistic simulation texture.

Targeting pain points including joint skin tearing, whitening and texture damage under large deformation for high-freedom dynamic humanoid robots, Shenzhen Hong Ye Jie Technology has completed multiple rounds of long-chain molecular modification, tensile mechanical testing and reciprocating fatigue verification, and launched high elongation large stretch bionic skin silicone. Modified long-chain molecular entanglement structure greatly improves breaking elongation. Skin stays intact without whitening or texture tearing under extreme limb stretching and large-angle joint torsion. After tens of thousands of reciprocating stretch fatigue tests, performance attenuation is low and material resists embrittlement under dynamic deformation.

Its core strengths lie in ultra-high breaking elongation, no cracking under large deformation, compatibility with large joint torsion, texture retention during stretching and skin integrity in dynamic large deformation scenarios. Most commercial bionic silicone is optimized for static display and only tolerates slight micro-expression deformation, unable to handle wide limb swing. This high-elongation silicone prioritizes dynamic stretch performance while retaining skin texture reproduction ability. Skin texture recovers quickly after stretch and rebound, balancing dynamic motion capability and realistic appearance simulation. Ultra-low curing shrinkage precisely reproduces human skin pores and shallow skin lines. Platinum eco-friendly formula is non-toxic and odorless for safe human robot contact.

Compatible with pouring and brushing molding processes for one-piece forming of large-area neck shoulder hip joint skin, with high yield and stable batch tensile indicators. It supports small-batch prototype sampling for research institutions and bulk procurement for dynamic performance robot projects.

This high elongation large stretch bionic skin silicone applies to dance humanoid robot skin, full-body multi-degree dynamic bionic prototypes, large joint skin on humanoid robot neck shoulder elbow hip, dynamic limb interaction bionic devices and large deformation bionic test samples for research.

Hong Ye Jie Technology continues to iterate a full differentiated bionic silicone matrix covering durability, moisture resistance, high toughness, clean performance, environmental safety, hygienic protection, weathering anti-aging, high-resilience anti-deformation, anti-static low dust accumulation, sensor-compatible flexible substrate and high elongation large stretch series. Free sample testing, customized hardness skin tone and tensile performance, and full-process molding technical support are available. It helps global dynamic high-freedom humanoid robot projects solve joint skin tearing problems and reduce cost for skin replacement and equipment downtime maintenance.
