Abstract :
The article reports a promising approach to engineering biocompatible and highly piezoresistive membranes for flexible weightless transparent pressure sensors. The developed membranes are based on bi layer (BL) films composing a polycarbonate (PC) matrix “self-metallized” with organic molecular metal β-(ET)2I3, were ET=bis(ethylenedithio) tetrathiafulvalene. The presented approach permits engineering biocompatible all-organic membranes with sensitivity to pressure being of 13 Ω/mmHg; this value is significantly over the sensitivity of the previous reported BL film-based membrane sensors.
