Study of screen printed polymer and ceramic based electrode on P(VDF-TrFE) flexible film

Abstract

This study reports the development of a reliable sensing P(VDF-TrFE) film sensor for the flexible structure sensing technology using a screen printing method. Good bonding between P(VDF-TrFE) and the structure is crucial for high voltage generation capability. In order to develop such a system, P(VDF-TrFE) film sandwiched electrical conductive electrodes were screen printed on the flexible structure. Silver palladium and polymer silver pastes were applied separately as an electrode material, Electrode quality test and FeSEM (Field Emission Scanning Electron Microscopy) were conducted on the post heat treated system to compare the bonding quality between the P(VDF-TrFE) film and the electrodes. Here, we demonstrate that the polymer silver forms a stronger bonding with the P(VDF-TrFE) film than the silver-palladium. The former also exhibits a lower electrical resistance than the latter electrode material.
