Fabrication of SnO<sub>2</sub> Flexible Sensor by Inkjet Printing Technology

Fabrication of SnO<sub>2</sub> Flexible Sensor by Inkjet Printing Technology

In this work, a flexible tin oxide (SnO<sub>2</sub>) gas sensor was successfully fabricated by inkjet printing technology. This thin film deposition technique requires the formulation of stable suspensions with specific fluidic properties. Aqueous Sol-gel method was applied to synthesize...
