Development of Ink that Detects Temperature Aberration for Safe and Reliable Quality Management

Release Digest

Example use of this aberration-detecting ink in distribution

Hitachi today announced the development of a new ink that detects and changes color when an aberration occurs in controlled temperature environments, to contribute to even greater safety and reliability in product quality management.

The ink has a property of changing color as a result of temperature change, and is able to detect when the ambient temperature exceeds the upper or lower limit set for each product. This process is irreversible, and so even if the temperature returns to the normal range, the ink color will not change back to its original color. Using this ink together with IoT technology, uninterrupted temperature monitoring of products such as fresh foods and medical supplies can be conducted throughout the entire supply chain, from production to consumption.
