Modern sex dolls are equipped with a range of advanced features that significantly enhance realism and user experience. One of the most prominent developments is the integration of articulated skeletons with multiple points of movement, allowing for natural posing and positioning. Some high-end models feature motorized components capable of mimicking breathing, head movements, and limb adjustments.

Another key feature is the use of lifelike skin materials that provide warmth, softness, and elasticity, often enhanced with embedded heating systems for a more realistic feel. Realistic facial features, including movable jaws, blinking eyes, and customizable expressions, contribute to a more immersive experience.

Many dolls now incorporate interactive technology such as voice recognition, touch sensors, and even AI-driven responses, enabling conversational interactions. Some models offer customizable or replaceable parts, including hair, eyes, and genitalia, to personalize the experience further.

Additional features include embedded heating elements, integrated sound systems, and compatibility with remote control apps. These innovations aim to create more lifelike, engaging, and personalized experiences, pushing the boundaries of what sex dolls can offer.
