Researchers have developed a crystalline material that when the voltage is supplied becomes flexible, and also can independently generate an electric current from pressure.
To create it, a team from Nanyang University has changed the chemical structure of the hybrid ferroelectric compound C6 H5 N (CH3) 3 CDCl3 and replaced in its composition some chlorine atoms on the bromine. These manipulations increased the flexibility of the material and weakened molecular ties at certain points of the structure.
The resulting crystal simultaneously manifests electrostrix and piezoelectric properties, that is, it can change the shape under the action of the current and produce electrical charges during deformation. The combination of these two qualities causes its high energy efficiency compared to other existing piezoelectric and electrical outrunning materials.
Experiments have shown that when an electric field is applied, a new hybrid can be stretched to 22% or 44 times more than the indicator of conventional piezoelectrics. This feature significantly expands the sphere of its potential use in electronics, actuating mechanisms and sensors.
According to the team, for the manufacture of such a crystal, powerful lasers and energy impact are not required, and only treatment is needed in the process of evaporation of the fluid. In the future, scientists plan to improve its characteristics due to the additional optimization of the chemical composition.
