"In the Life Science exhibit at the Science Museum, an elegantly designed spiral installation attracts many visitors with its unique interactive experience. Touching the metal surface and pressing the start button initiates a scientific exploration of temperature sensing. At the heart of this exhibit is a meticulously crafted spiral metal shaft, integrating an advanced temperature control system. Visitors place their hands on the shaft and, upon activation, experience alternating changes in temperature: sometimes as gentle as the spring sun, sometimes as cool as a flowing spring. This instantaneous temperature shift not only provides a fascinating sensory experience but also allows for a direct understanding of how the skin perceives temperature differences. Unveiling the Scientific Principles of Sensing: Deep within our skin are two types of temperature receptors, each responding to hot or cold stimuli. The exhibit activates these receptors through precise temperature control, allow
