- 5. Materials Characterization Lab www.mri.psu.edu/mcl What's Dielectric Characterization? E.G.: conductivity (V=RI), permittivity (D= E), impedance (V*=Z*·I*), piezoelectricity (P=dσ), pyroelectricity (i=p·dT/dt), ferroelectricity (nonlinear relationship between electric field, polarization, strain, ...) For sure it involves charge and many orders of magnitude.

Materials Characterization Lab www.mri.psu.edu/mcl How To Get Started contact: Jeff Long or Paul Moses you will need: ― a question or a plan ― a sample with electrodes, contacts, or connections ― a budget/fund number (cost center/project number) ― possibly expendables: silver foil, dielectric fluid ― possibly special fixture
