    Abstract: A passive sensor for historic age and temperature sensing, including a first member formed of a first material, the first material being either a metal or a semiconductor material and a second member formed of a second material, the second material being either a metal or a semiconductor material. A surface of the second member is in contact with a surface of the first member such that, over time, the second material of the second member diffuses into the first material of the first member. The rate of diffusion for the second material to diffuse into the first material depends on a temperature of the passive sensor. One of the electrical conductance, the electrical capacitance, the electrical inductance, the optical transmission, the optical reflectance, or the crystalline structure of the passive sensor depends on the amount of the second material that has diffused into the first member.

  • Patent number: 8695528
    Abstract: A release of the frozen solvent trapped inside a solidified gel occurs when the temperature increases, followed by a dissolving of a reactive substance present in a membrane that is located in direct physical contact with the gel, resulting in the reabsorption of the reactive substance dissolved in the solvent into the solid gel layer within a constant time. In this manner, the components generating color change come together within the solid gel layer initiating a reaction to change the color of the indicator layer. Thus, the increase in temperature above a melting point of the solid gel layer is enough to activate the intelligent label with an irreversible color change.

    Abstract: A temperature descending indicator which gives a visual indication when the indicator has been exposed to temperatures below a set threshold temperature includes a container having a translucent portion, a first temperature sensitive gel of a first color which will convert to liquid when it is exposed to temperatures below the set threshold temperature, and a second temperature sensitive gel of a second color which will convert to liquid when it is exposed to temperatures below the set threshold temperature, wherein the second temperature sensitive gel is disposed adjacent said translucent portion in a manner to obscure the visibility of the first temperature sensitive gel. A method of making the indicator includes disposing one color gel over the other.

  • Publication number: 20130010827
    Abstract: This invention relates to temperature indicators, particularly the invention relates to temperature indicators which can be used to indicate the temperature of temperature changing material or element. The disadvantages of prior art solutions include the toxicity of the material acting as an indicator or the poor ability to detect the colour change. In the solution according to the invention, the temperature indicator contains bismuth oxide and potentially one or more colouring pigments mixed into the bismuth oxide.

  • Patent number: 8316789
    Abstract: A temperature sensing device includes a casing having top and bottom walls with at least one wall connecting the top and bottom walls so that the casing is sealed, the top, bottom, and side walls being constructed of a heat resistant material. The sensing device includes a probe having a first portion attached to the casing bottom wall and extending downwardly and a second portion situated inside the interior space, the first and second portions being operatively connected to one another to transfer thermal energy therebetween. The probe second portion is coated with a thermochromic material that is color responsive to temperature. At least one wall of the casing defines an aperture that is covered by a material that is heat resistant, the probe second portion being viewable through the aperture for determining a temperature of an article of meat.

  • Publication number: 20120147926
    Abstract: A heat conductive structure for a thermometer with a structure with temperature indication markings includes a probe structure with a thermal conductive surface. A temperature indication portion is disposed adjacent to the probe structure. A reversible temperature-sensitive color changing layer is formed on the temperature indication portion to overlap the structure of the temperature indication markings. The probe structure is adapted for sensing the thermal contact surface to conduct heat flow to the reversible temperature-sensitive color changing layer, producing a sensed temperature and a color changing zone of the reversible temperature-sensitive color changing layer in response to the sensed temperature thereby exhibiting a corresponding temperature value.
