Abstract
This paper presents a fabrication technology for a piezoelectric pressure mapping sensor with a PVDF film sandwiched between metal wire electrodes. A new approach is proposed for a poling treatment of the polymer films, which is generally required to obtain a sufficient voltage output from the sensor, using a simple solution-based method of drop-casting onto the chemically modified electrode surface. Here we report on the fabrication method and an investigation of the functionality of the fabricated novel mapping device, which can detect the applied position for a two-dimensional pressure mapping.
