Methods and systems for measuring the temperature of a sample can include the use of one or more illumination sources and a sample containing thermochromic material. One or more detectors are operable to detect two or more signals indicative of a component of an illumination facilitated by the illumination source(s) and scattered at two or more angles with respect to the sample containing the thermochromic material, wherein the signals are converted to a temperature.

The invention involves the incorporation and enablement of multiple interactive elements into high-volume consumables products to increase utility, function and features of the consumable product at minimal incremental cost and adjustment to production and manufacturing processes. The invention further reports processes and compositions that enable consumable products with differentiating features which product would otherwise be deficient for their intended use and application.

Temperature measurements of photonic circuit components may be performed optically, exploiting a temperature-dependent spectral property of the photonic device to be monitored itself, or of a separate optical temperature sensor placed in its vicinity. By facilitating measurements of the temperature of the individual photonic devices rather than merely the photonic circuit at large, such optical temperature measurements can provide more accurate temperature information and help improve thermal design.

The invention relates to a method for monitoring the temperature of a cryopreserved biological sample. The invention also relates to a device for monitoring the temperature of a cryopreserved biological sample. The device (10) for monitoring the temperature of a cryopreserved biological sample comprises a sample container (1) having a receiving space (2) for receiving a biological sample (6). The device also comprises at least one chamber (11) having an interior that is not fluidically connected to the receiving space (2) and is only partially filled with an indicator substance (7) with a melting temperature in a region of −20° C. to −140° C. The chamber (11) has a barrier (13) that causes the indicator substance (7) to move into a second sub-region (12b) of the chamber (11) when the indicator substance (7) in a first sub-region (12a) of the chamber is in the fluid aggregate state.
