What happens when i apply dc current in them?
And ac aswell?
Im quite confused about them tbh.
Edit:
Dielectric*

thanks.Baluncore said:It is the electric stress on the capacitor dielectric that has the effect, so it is not current flow that has the effect.
Unless the material is polarised, as in an electret, the effect will be symmetrical and not polarity dependent. I would expect a sine wave to make 2'nd harmonic distortion unless DC bias voltage prevented zero crossings.
Dielectric elastomers are a type of material that can stretch and deform when subjected to an electric field. They are made up of a thin, flexible layer of an insulating material sandwiched between two layers of electrodes.
Dielectric elastomers work by using the applied electric field to attract or repel the charged particles in the material, causing it to expand or contract. This change in size can be harnessed for various applications, such as actuation and energy harvesting.
Some advantages of using dielectric elastomers include their lightweight and flexible nature, as well as their ability to produce large strains and high energy densities. They also have low power consumption and can be easily integrated into complex systems.
Dielectric elastomers have a wide range of applications, including artificial muscles, soft robots, haptic feedback devices, and energy harvesting devices. They can also be used in medical devices, such as prosthetics and drug delivery systems.
Some challenges in using dielectric elastomers include their limited lifespan and their sensitivity to temperature and humidity. They also require high voltages to operate, which can be a safety concern. Additionally, the manufacturing process for dielectric elastomers can be complex and costly.
