Abstract
A pressure distribution monitoring flexible planar mat system with a wide pressure measuring range. The flexible planar mat includes a first electrode layer and a first composite piezoelectric-dielectric layer with a second composite piezoelectric-dielectric layer facing the first layer and a second electrode layer. Each of the first and second composite piezoelectric-dielectric layers includes an elastomeric matrix with conductive and dielectric particles embedded therein. The relative size of the conductive particles and the dielectric particles creates a micro-rough interface between these layers and the electrode layers resulting in a range of contact areas, permitting detection between 0 and 3000 kPa. The flexible planar mat system further includes a data collector that collects a pressure signal from the mat. A pressure distribution data processor receives and calculates data from the data collector and creates a two-dimensional pressure map from the flexible planar mat.
