Vaccines are biological products that must be kept between 2?and 8? C, if not, they are losing effectiveness to the point of total inactivity. Searching for enhance useful life of vaccine when required to be transported to remote locations, it has been proposed to use a mobile monitored cooling system (SMRM, for its Spanish acronym) using a graphene reinforced polymer nanocomposite. Latter, improve cooling or heating speed of thermal, electric and electronic devices. Such improvement aims to ensure SMRM?s transported vaccine has a lesser exposure to outer specified temperatures, allowing a higher efficiency than transported with commercial systems. Finally, when achieved a cooling rate of 1.54 (?C/min) and energy consumption of 6.67 W/h, a significant improvement was remarkable, that compared to commercial system yields 200% higher cooling rate and 41% less energy consumption.
