Organic thin film transistors on shape memory polymers are fabricated by full photolithography. Devices show high mobility (0.2 cm 2 V −1 s −1 ) and close to zero threshold voltage (‐4.5 V) when characterized as fabricated. After 1, 10, and 100 deformation cycles and in a deformed, metastable shape memory transition state, changes in mobility and V th are measured and indicate sustained device functionality.
