A large gain in pyroelectric voltage and current when exposed to infrared radiation after candle soot coating on material surfaces is reported. A piezoelectric buzzer is selected to quantify the effect of candle soot on pyroelectric output. For a given temperature change, the peak value of the open‐circuit voltage is enhanced from 2 V to 8 V and electric current is boosted from 15 nA to 95 nA. A load capacitor is also connected through a full wave rectifier. Energy storage in a 10 μF load capacitor is increased from 5 nJ to 70 nJ.

“…Recently, candle soot was also reported for improvement in output energy density . Another study uses concentrated solar radiations on a lead zirconate titanate (PZT)‐5H pyroelectric material for producing higher rate of temperature fluctuations using a wind turbine, thereby generating substantial energy and power densities . Furthermore, a pyroelectric material coated with diesel exhaust emission soot shows significant enhancements in terms of electrical parameters .…”

It is now well reported that the coatings of graphene/candle soot/black carbon can improve the performance of pyroelectric materials. Herein, the performance of candle soot‐coated pyroelectric material (piezoelectric buzzer) under solar heating is reported. To compare the performance, coated/uncoated piezoelectric buzzers are exposed to solar light as well as IR lamp separately. Piezoelectric buzzer shows multiple times superior performance after coating of candle soot. The open‐circuit voltage improves five times with a peak voltage of 3.31 V in solar light. The comparative enhancement in short‐circuit pyroelectric current is four times with a peak current of 2.73 μA. Also, the power and energy densities show multifold enhancement after coating.

The structural and pyroelectric properties of partially Ca‐substituted BaTiO3, Ba1−xCaxTiO3 (0 ≤ x ≤ 0.2), are investigated. Partial Ca‐substitution in BaTiO3 introduced tetragonal distortion in the TiO6 octahedrons and increased the displacement, Δd, of a Ti4+ cation from the center of an octahedron. This increase in Δd led to enhancement of remanent polarization and pyroelectric voltage, Vp. The pyroelectric energy storage behavior is demonstrated for the partially Ca‐substituted BaTiO3. For the Ba0.9Ca0.1TiO3 sample which exhibited the highest Vp, the stored energy in an output capacitor was proven to be sufficient to operate micropower Internet of Things devices.
