Abstract: This article is addressed to the development of flexible lightweight physical sensors suitable for body sensing technology. The polycarbonate films were covered with different organic molecular conductors to fabricate flexible strain sensing materials. The resulting surface-modified films were fully characterized by different microscopic and spectroscopic techniques and their electric transport and electromechanical properties were studied as well. The investigations demonstrated that the electrical responses of these films suffice to measure very small pressure or temperature changes. A series of proof of concept prototypes of strain sensors were designed and a portable system including wireless data transmission was developed.
Keywords: Flexible strain sensor, Deformation sensing materials, Organic molecular conductors, Electrical detection principle; Wireless data transmission
