Abstract
Functionality of nano composite Paint/PLZT films for use in pyroelectric infrared sensors and piezoelectric energy harvesting devices is presented. Smart Paint/Lead Lanthanum Zirconate Titanate (Paint/PLZT) nanocomposite films have been fabricated by the conventional paint-brushing technique on copper substrate. The pyroelectric and dielectric properties of the composite films were measured for their use in uncooled infrared detectors and thermal energy conversion devices. The properties investigated include: dielectric constants (ε' and ε’’); pyro electric coefficient (p); and conductivity as a function of temperature. From the foregoing parameters, material’s figure-of-merits, for infrared detection and thermal energy conversion, were calculated. The results indicated that composite films are functional and figure-of-merits increase with increase in amount of PLZT nanoparticles in paint. Based on the preliminary results obtained, it was found that the Paint/PLZT films are attractive for use in un-cooled thermal sensing elements and thermal energy conversion devices, especially in applications where flexible and curved-surface sensors are required. Efforts were also made to investigate the performance of nanocomposite films on copper substrate to mechanical vibrations. Thus, could be utilized for energy scavenging combining piezoelectric and pyroelectric effects. [This work is funded by NSF-HRD-1546965 grant.]
