Developers who pursue extreme reality have begun to pay attention to the reproduction of microscopic physiological characteristics. A US startup uses 3D printing vascular network technology to build a recyclable liquid system 1.2 mm below the scalp of the sex doll to achieve biological characteristics such as blushing and lip color changes. When the room temperature is below 20°C, the temperature control module connected to the torso sex doll will start the blood circulation simulation to maintain the surface temperature of the sex doll head at 36.5±0.3°C. This technology extends the health monitoring function-by analyzing the simulated metabolites in the "blood", the pressure index of the user's body during contact can be evaluated. However, such a complex system increases the maintenance cost of the sex doll head by 3 times, and special maintenance equipment is required.
