Abstract Scope Flexible electronics can retain electrical properties through various deformations and can be interfaced with curvilinear surfaces unlike silicon-based devices. Flexible organic transistors based on dinaphtho-[2,3-b:2'3'-f]thieno[3,2-b]thiophene (DNTT), a semiconductor with a high ionization potential, were fabricated on a shape memory polymer (SMP) substrate. SMPs are a class of stiffness-changing smart materials that can recover an imparted strain when heated above a tunable glass transition temperature and could facilitate the chronic use of sensing devices inside the body. By tuning the glass transition temperature of the SMP substrate, devices can be fabricated that soften and conform to complex, 3D surfaces when heated to body temperature, enabling future biomedical devices that are compliant to surrounding tissue and stationary after implantation. These devices on SMP substrates exhibit a mobility of 1 cm^2/V-s, a threshold voltage of 0.7 V, and an on/off current ratio of 10^5.
