ABSTRACT:
Aspects described herein provide for the design and fabrication of a device with an enhanced pyroelectric response signal comprised of multi-capacitors that are connected in series. These capacitors are fabricated using multi-layers of materials such as lead zirconate titanate (PZT), BaxSr1-xTiO3(barium strontium titanate) and Bi4Ti3O12(bismuth titanate) films that exhibit pyroelectric affect and belong to the class of polar materials. By controlling the poling direction of the multi-layer integrated structure, the pyroelectric voltage can be aligned in one direction, and as a result, the voltage output from the single element is the total contribution from each capacitor.
