T-tag

Scriba Nanotecnologie has developed an innovative time-temperature integrator (TTI) architecture. A TTI is a device recording the thermal history of packaging, and it is used to monitor the storage conditions of perishable products.

Our TTI is a completely passive time-temperature integrator (it does not require batteries or other power sources). It operates in the temperature range between -20 and 70 °C, monitoring the exposure to a temperature higher than a threshold temperatures (2, 8, 17, 26 °C). It is an adhesive label directly coupled with anti-counterfeiting miniaturized code En-TAG™. Indeed, it is composed of two distinct layers. The first one is a semi-transparent micrometric data-matrix (En-TAG™) containing sensitive data about the products in a small area (3×3 mm²). The second one is made of a thin microfluidic device, aligned with En-TAG™, which confines a thermosensitive formulation with defined optical properties. Accidental exposure to heated environment with temperature higher than threshold temperature is recorded by the interaction of thermosensitive materials with the nanostructured En-TAG.

Competitive advantage of T-TAG

The advantages and benefits of the T-TAG solution are:

  • capability to record "thermal excursions" above threshold temperature with a resolution of 4 hours (10%) over periods of 2 days, even in the case of multiple exposures;
  • digital readout of the thermal exposure with an App developed by Scriba for Android smartphones, automating the readout and simplifying the interpretation for the final user;
  • innovation on the label design (16mm x 20mm and 1mm thickness), enabling an effective and compact integration on primary packaging.

T-TAG employment

Two of the production/distribution market segments where TTIs are needed is the cold chain logistics of food or pharmaceutical products (encompassing antibiotics, vaccines and monoclonal antibodies).

T-TAG allows to identify the points in the cold-chain at which unnecessary "thermal excursions" take place, helping to reduce waste and costs for the food and healthcare industries, and guaranteeing the quality and safety of the products.

Our TTI device can be employed for monitoring not only the storage conditions of perishable products, but also the timing of access to infrastructures requiring security check (i.e. airports), or the occurrence of tampering in documents that are at risk of counterfeit.
