Adv. In general, e varies slightly, depending on the strength of the electric field, but for some materials, called linear dielectrics, it is a constant. The dielectric constant can be calculated using: = Cs / Cv , where Cs is the capacitance with the specimen as the dielectric, and Cv is the capacitance with a vacuum as the dielectric. Polyethylene terephthalate polyester (PETP) is the most common thermoplastic polyester and is often called just polyester. Its thermal conductivity is higher than all other gases, it has high specific heat capacity, low density and therefore low viscosity, which is an advantage for rotary machines susceptible to The robots are driven by multi-layered dielectric elastomer actuators that weigh 100 milligrams each and have a resonance frequency of 500 hertz and power density of 600 watts per kilogram.
