A roll transfer printing method for In-Ga-Zn-O (IGZO) thin film transistors (TFTs) on a stretchable substrate is demonstrated. The TFTs’ electrical performance is investigated under stretching and cyclic tests. Mechanics involved in the transferring process are investigated and simulated, which shows that the strain level experienced by the device's active layers is well below the maximum fracture level.
