Smart nano composite paint sensors for infrared detecting and energy harvesting

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.]
