Abstract
In this work, we propose a multi-sensor platform where sensors are stacked over one another (3D stacked) each offering a unique functionality. The technique involves the use of Polyurethane (PU) sponge and PVDF/graphene (Gr) /ZnO composites for various sensing applications. The sponge was made conductive by dipping it in different weight percentages of pencil lead dispersed in ethanol through ultrasonication. Large area Gr/PVDF films were fabricated by simple solution mixing and casting method which also served as a substrate for the 3D stacked sensor. ZnO was grown hydrothermally over Gr/PVDF film by masking a portion of Gr/PVDF film to form a p-n junction. Silver paste and copper tape were used as contact pads. All the three fabricated devices were stacked with PU sponge sandwiched between Gr/PVDF/ZnO (top) and large area Gr/PVDF (bottom) as substrate. Performance of individual sensors and 3D stacked sensor was compared and no notable change was observed. The 3D stacked sensor array platform with its multifunctionality would be a step ahead in wearable electronics which can be integrated on human and can function as an e-skin for burn and acid victims, robotics and human-machine interactions.
