This paper demonstrates the significant benefits of exploiting highly aligned porosity in
piezoelectric and pyroelectric materials for improved energy harvesting performance.
Porous lead zirconate (PZT) ceramics with aligned pore channels and varying fractions of
porosity were manufactured in a water-based suspension using freeze-casting. The aligned
porous PZT ceramics were characterized in detail for both piezoelectric and pyroelectric
properties and their energy harvesting performance figures of merit were assessed parallel …
