Abstract

In the world of constant facilities of human life, as well as improving the comfort of patients, there are more and more reports on non-invasive methods of testing and health related procedures. One of the most common invasive procedures performed by patients is the procedure of taking blood from the fingertip to the glucose test. It is not surprising, therefore, that the attention of researchers around the world is focused on eliminating the need for invasiveness of these tests. The tendency to facilitate and minimize interference in body coherence concerns all tests with which diabetic patients come in contact. In the light of this trend, a promising idea seems to be the possibility of non-invasive measurements of one of the conditions associated with diabetes - ketoacidosis. Such novel and non-invasive procedure is for example monitoring the amount of acetone exhaled with air by a diabetics suffering from ketoacidosis. In this work we present the sensors of acetone vapors based on titanium oxide and graphene nano-flakes or carbon nanotubes fabricated using a screen printing technology on the ceramic substrate. We have also performed test of sensitivity of fabricated sensors into the acetone gases presence in both room temperature and 150° degrees.
