For it to operate underwater, the team used piezoelectric materials in its construction so that it will be powered by the bobbing of the waves.

Not exact matches

These materials are also used in everyday devices, such as loudspeakers, which rely on piezoelectrics to convert electrical signals to mechanical vibrations which create sound waves to produce the desired acoustic signal.

Another group of collaborators, led by Professor Jiangyu Li at the University of Washington in Seattle, tested the material using a state of the art apparatus and proved it was, indeed, piezoelectric.

This new tag uses a flexible strip containing piezoelectric materials, which generate electricity through physical movement.

The team used the strain induced by an electric field applied to a piezoelectric material (which deforms mechanically in response to an electric field) to manipulate the chirality of the domain wall.

So far, however, attempts to harvest this energy using vibrating plates or piezoelectric materials, which produce electricity when compressed or bent, have mustered only a few milliwatts.

The new materials, which generate an electric field when squeezed, copy the crystal structure of conventional piezoelectric materials but use bismuth instead of lead.

Piezoelectric materials, which generate an electric current when compressed or stretched, are familiar and widely used: think of lighters that spark when you press a switch, but also microphones, sensors, motors and all kinds of other devices.

«We can directly create piezoelectric materials of the shape we want, where we want them, on flexible substrates for use in energy harvesting and other applications,» said Nazanin Bassiri - Gharb, co-author of the paper and an assistant professor in the School of Mechanical Engineering at the Georgia Institute of Technology.

We have seen piezoelectric transistors incorporated into synthetic skins making them sensitive enough to read fingerprints, other approaches that use multipurpose sensors to detect temperature and humidity in addition to pressure, and others that use pressure - sensitive materials made from inorganic semiconductors to only use a small amounts of power.

Abstract: Piezoelectric materials, which generate an electric current when compressed or stretched, are familiar and widely used: think of lighters that spark when you press a switch, but also microphones, sensors, motors and all kinds of other devices.

Lookman and his colleagues focused on nickel - titanium - based shape - memory alloys, but the strategy can be used for any materials class (polymers, ceramics or nanomaterials) or target properties (e.g., dielectric response, piezoelectric coefficients and band gaps).

This new energy harvesting device uses an electrochemical process similar to that in lithium ion batteries to produce electricity instead of a physical process like the other piezoelectric materials, which will likely make it inexpensive to manufacture.
