The PEC uses a pyroelectric composite material, as the separator in an electrochemical cell.

It could also lead to new technology, Sharma says: “We can use the same model to create artificial materials that have pyroelectric properties for exciting applications in materials science.”

Hence, irrespective of the intrinsic symmetry of the bulk, surfaces can, in theory, be polar and even pyroelectric.

Ha�y in 1791, the crystals are markedly pyroelectric; a cube when heated becomes positively electrified on four of its corners and negatively on the four opposite corners.

The current disappears once the temperature stabilizes; the time taken for this to happen carries information about the time taken to reach thermal equilibrium, which is proportional to the volume of pyroelectric material.
