a multi disciplinary research team made up of engineers and chemical scientists from the university of granada has developed an intelligent mask that alerts wearers on their smartphones . when recommended c o 2 limits are exceeded. lemme for the dental, he think they're going see intelligent mass has a sensor, meaning a way to measure something in the air between your face and the mask. britta introduce gotta la guardia. and so the c o 2 sensor is equipped with the electronics that will measure the color change in the sensor, but, and transmit that information to a smart phone. and the sensuality inputted upon me, delinquent mouth, you know, telephone all mo, so a standard f, f, p to mask can be turned into an intelligent mask that monitors gas concentration by placing a special electronic sticker inside the mask. let me get that getting blue is that occur inserted inside the mask is a system that consists of 2 parts on one side there's what's called read out electronics, which is printed with conductive ink on a flexible, plastic, and transparent substrate to receive. as you can see, i think
