Electroactive polymers strain sensors bear a great potentiality in the area of soft robotics, wearable devices, and fitness
industries. A small initial defect present in such sensor may grow to a critical size during contraction and relaxation
cycles leading to mechanical failure, therefore, prediction of fatigue life is inevitable. The crack growth approach is
one of the amicable ways to estimate the fatigue life considering parameters like tear energy, crack geometry, and
power law. In this work, crack growth approach based on power law is being proposed to predict fatigue life utilizing
conducting and stretchable freestanding films consisted of SEBS rubber and dodecyl benzenesulfonic acid (DBSA)
doped polyaniline composite. Utilizing this crack growth model for the prediction of fatigue life exhibited that such
films can sustain more than a million cycles even at a large value of deformation.

Conjugated polymers (CPs) offer adequate freedom to improve the charge transport in their thin films by tuning their chemical structure or processing techniques aiming towards enhancing their crystallinity. Exploiting quasi 1-dimensional nature of CPs is one of the best possible approaches to improve the carrier transport by uniaxially orienting them along the channel of an organic field-effect transistor (OFET). Various solution-based approaches in order to orient the CPs leading to high-performance OFETs has been demonstrated, however, the limitations like need of good solubility of the CPs, surface wettability, pre-aggregation in solution, etc., are the bottleneck to generalize them. Moreover, inevitability of halogenated solvents for film fabrication may also lead to serious health and environmental hazards during large scale production. Friction transfer is a solvent-free processing technique to fabricate large-area oriented polymer thin films and can effectively be utilized to overcome aforementioned challenges. In this work, role of dielectric surface to control the anisotropic charge transport in the OFETs has been extensively investigated and considering the optical and electrical characteristics, a possible transport mechanism has been proposed.
