Editors' note:

Mechanical strain significantly affects thin-film transistor (TFT) device mobility; thus, strain awareness is indispensable to flexible TFT circuit design. This article presents a strain-aware placement technique to enhance TFT logic circuit performance in the presence of mechanical stress.
