Sensing Sticker

Sensing stickers change color at specific temperatures or pressures using thermosensitive or pressure-sensitive materials, indicating whether an object has been exposed to heat or pressure. They are commonly used in food packaging and electronic components to show if a product has experienced overheating or excessive pressure.
Selection
When selecting sensing stickers, consider the temperature range, response time, adhesion surface, and cost. Match them to application scenarios such as cold chain monitoring or industrial inspection to ensure the sticker's performance meets actual needs and avoid over- or under-specification.
