Color changing principle of temperature sensitive color changing stickers

Temperature-sensitive color-changing stickers are a type of office supply material made using thermochromic technology. These stickers come in equal-sized square or circular shapes, and their color changes depending on the surface temperature of the object they are attached to. Temperature-sensitive color-changing stickers have a wide range of applications in daily life, such as monitoring bathroom temperature, controlling indoor temperature, and adjusting hot water bottle temperature.

The color-changing principle of temperature-sensitive color-changing stickers relies on the thermochromic properties of thermally sensitive materials. Thermally sensitive materials are materials that can respond significantly to temperature changes. When the temperature rises or falls, the color of the thermally sensitive material changes. The thermally sensitive materials used in temperature-sensitive color-changing stickers exhibit thermochromic properties within a certain temperature range, meaning that the color change only occurs when the surface temperature of the material falls within this range.

Application of temperature sensitive color changing stickers

Temperature-sensitive color-changing stickers have a wide range of applications in daily life, with common usage scenarios including:

  1. Temperature detection: Temperature-sensitive color-changing stickers can be used in bathrooms, indoors, and other places to detect temperature changes, thereby controlling indoor temperature.

  2. Hot water bottle temperature adjustment: Temperature-sensitive color-changing stickers can be used to adjust the temperature of hot water bottles, making them suitable for human use.

  3. Food temperature detection: Temperature-sensitive color-changing stickers can be used to detect the temperature of food, preventing injuries from consuming food that is too hot or too cold.

  4. Medical applications: Temperature-sensitive color-changing stickers can be used in the medical industry, for example, for skin temperature detection, operating room temperature monitoring, and other purposes.

Temperature sensitive patch

The temperature-sensitive patch is a simplified adhesive-type thermometer used in medical, industrial, and other fields, characterized by its diverse types, wide applications, and low cost.

A temperature-sensitive patch can be regarded as a simplified adhesive-type thermometer. Like a sticker, it does not require batteries or other forms of energy. When the temperature reaches the rated temperature of the patch, it begins to change color, thereby alerting the user to the temperature change.

Temperature-sensitive patches can not only be used to measure human body temperature but can also be applied to medical and industrial equipment. By simply attaching the patch to various heat-generating components of the equipment, users can detect abnormal temperature areas in electrical and mechanical devices early on, investigate the causes, and make improvements promptly, thereby preventing equipment damage and accidents. This also enhances workplace safety and protection.

Types of temperature sensitive patch labels

Reversible type: The temperature component changes color but returns to its original color after cooling. It can be reused continuously.
Irreversible type: The temperature component changes color but does not return to its original color after cooling. It cannot be reused.

Temperature-sensitive patches come in various styles, such as square with a circular interior, square with a square interior, etc. The sizes range from large ones that are 10cm x 10cm and can be identified with the naked eye from 10 to 20 meters away, to small ones that are 5mm x 5mm specifically for use on tiny electronic components. Due to their diverse types, wide applications, and low cost, they can meet the needs of most users.
