Fabrication and application of low cost flexible film-based sensors to environmental and biomedical monitoring scenarios

Abstract

The paper describes the development of flexible lightweight highly sensitive film-based sensors capable of monitoring pressure, deformation, temperature and humidity. In particular, we present a family of the developed simple devices that successfully adopted polycarbonate films covered with organic molecular conductors as conductive sensing components. Proof-ofconcept experiments with these prototypes demonstrate that such bi layer films are promising as sensing devices for the environment and biomedical monitoring. Besides, we present the interfacing of the flexible film-based sensor with a wireless sensor node and evaluate the sensing capability of this system in a real monitoring scenario.
