초록
In this paper, a mechanism of micro crack sensor based on electrohydrodynamic printing is studied. Inks are made by stirring sufficiently silver nano paste with Alpha-terpineol and BDGA(Diethylene glycol monobutyl ether acetate). The polymer PVP is added to the stirred inks to investigate the effect of the polymer on the droplets discharged. To make the grid type of the sensor, several lines are patterned on the upper and lower surfaces of the structures at regular intervals in the horizontal or vertical direction. It is confirmed that the resistances are changed by generating arbitrary cracks in the grid sensor, and the position of crack occurrence is detected by using the intersection point of the changed resistances.
