Titolo:  Organic bendable and stretchable field effect devices for sensing applications
Data di pubblicazione:  2013
Abstract:  In this paper we propose a detailed investigation on the electrical response to mechanical deformations of Organic Field Effect Transistors (OFETs) assembled on flexible plastic substrates. We demonstrate that, by applying a surface deformation by an external mechanical stimulus, we induce morphological and structural changes in the organic semiconductor, giving rise to a marked, reproducible, and reversible variation of the device output current. We show how the intrinsic properties of the employed active layers play a crucial role in determining the final sensitivity to the mechanical deformation. Finally we also demonstrate that the fabricated flexible system can be successfully employed for different applications that go from the detection of bio-mechanical parameters (e.g., joints motion, breath rate, etc.) in the wearable electronics field, to tactile transduction for the realization of artificial “robot skin”.
