Piezoelectrics

Material can turn sunlight, heat and movement Into electricity -- all at once

Extracting energy from multiple sources could help power wearable technology.

A perovskite solid-solution that exhibits tunable bandgaps in the visible light energy range is showing promising material for light absorption and conversion applications,(solar energy harvesting and light sensing).

Such a common ABO3–type perovskite structure, most widely used for ferroelectrics and piezoelectrics, enables the same solid-solution material to be used for the simultaneous harvesting or sensing of solar, kinetic, and thermal energies.

These results are considered to be a significant improvement compared to those of other compositions which could be used for the same applications. The results pave the way for the development of hybrid energy harvesters/sensors, which can convert multiple energy sources into electrical energy simultaneously in the same material.
