The intelligent beauty of temperature response
The chubby sex doll is equipped with thermochromic microcapsules. After contact with body temperature, the local hue value (H) shifts by +8°, ​​simulating the effect of congestion. The full body sex doll is more advanced with integrated PTC materials. The breast area is heated from 25℃ to 37℃, and the softness is increased by 40% and the volume expands by 3%.

Paragraph 11: The artistic balance of weight
Exquisite full-body sex dolls require density gradient design: 0.98g/cm³ for the chest (simulating fat) and 1.05g/cm³ for the buttocks (close to the muscles). Because the thick sex doll is larger in size, hollow glass microbeads need to be filled in the abdominal cavity to maintain visual fullness and control the total weight within 90% of a real person.
