Self-adaptive system for temperature control: A dynamically controllable strategy for healing wound tissue

Physorg.com - 6 мая, 2024 - 21:28
Skin functions as a sophisticated sensorial system in the human body, capable not only of detecting environmental stimuli—such as temperature, pressure, strain, and vibration—but also of actively responding to these changes. Among these, the temperature regulation capability of the skin plays a critical role in maintaining the stability of homeothermic animals.
