Patent number: 12078550Abstract: A temperature sensor, and methods of making and using such a temperature sensor, whereby the temperature sensor includes a reversible thermochromic color-changing system having a dye, a developer, and a solvent. Upon exposure to a preselected temperature threshold, association or disassociation of the dye and the developer results in a visible color change. Further, the color-changing system includes a color-memory property which facilitates retention of the color change to effectively record exposure to the temperature threshold.Type: GrantFiled: March 31, 2020Date of Patent: September 3, 2024Assignee: Chromatic Technologies, Inc.Inventors: Lyle Small, Timothy J. Owen, Ruizheng Wang, Medhanei Abraha

Patent number: 10605681Abstract: A pressure sensor and its use for visually determining whether a preselected pressure threshold has been achieved, for example during high pressure processing treatment of a foodstuff. The pressure sensor includes a contained color-changing system having a dye, a developer, and a solvent; upon achievement of the preselected pressure threshold, the dye and the developer interact, resulting in a visible color change. Further, the visible color change can be retained upon a decrease in pressure and upon an increase in temperature, thereby effectively recording the achievement of the preselected pressure threshold during the high pressure processing treatment.Type: GrantFiled: September 12, 2018Date of Patent: March 31, 2020Assignee: Chromatic Technologies, Inc.Inventors: Ruizheng Wang, Timothy J.
