it is used for thermal detectors and infrared imaging.
Energy harvesting
Waste heat
with a cold thermal reservoir
and an oscillating working fluid
can use the Olsen cycle
with a pyroelectric material
to generate a small
amount of electricity.
Wasted
Wasted time,
wasted love,
every sparrow that falls
is precious
as is
a contemplative moment,
a walk in the woods,
a lesson learned.
The electrocaloric effect is the physical inverse of the pyroelectric effect,
which is when a material gains a temperature change in an external electric field.
