The core challenge of achieving autonomous movement of the new sex doll lies in the breakthrough of miniaturized power system. The raditional torso sex doll relies on fixed bases or manual adjustment, while autonomous movement requires the integration of high-precision servo motors in limited space. The bionic muscle fibers developed by a Japanese laboratory achieve human-like joint movement through electroactive polymers, and the energy consumption is 58% lower than that of traditional motors. This material breakthrough enables new sex dolls to complete complex movements such as serving tea and hugging, but the balance between torque control and energy density needs to be solved. A more cutting-edge solution is magnetic levitation joint technology, which can eliminate mechanical friction noise and is particularly suitable for private scenes that require silent movement.
