What are the challenges of achieving lifelike skin textures using composite materials?

Creating lifelike skin textures with composite materials presents several significant challenges. One major hurdle is achieving the right balance of flexibility and durability—real skin is both soft and resilient, while synthetic materials often compromise one for the other. Another issue is replicating the subtle variations in color, translucency, and surface details like pores and wrinkles, which are difficult to mimic with artificial compounds. Additionally, composite materials must withstand environmental factors like UV exposure and moisture without degrading, a requirement that many current synthetics struggle to meet. Finally, integrating these materials with robotics or prosthetics for natural movement adds another layer of complexity. Overcoming these obstacles is crucial for advancements in medical prosthetics, robotics, and even entertainment industries.
