Abstract: In this study, a water-based eco-friendly solution of Titanium Carbide MXene was ultrasonically spray coated on Si/SiO2 substrate for the detection of sweat substances. The optimal flow rate of the solution was found to be 0.15ml min, and the resulting films had a surface roughness of ∼ 17 nm and sheet resistance of 156 Ωsq. Chemoresistive sensors with titanium and aluminum contacts were fabricated and their response to (MgCl2,NH3. and .NaCl) was measured. The most stable and strongest response was toward MgCl2 from sensors with Ti contact.
