Abstract Mechanical‐stress‐induced voltage or current in epoxy polymers appears to be a function of the state of order of dipoles in the surface layer. The sign and magnitude of the voltage is correlated with the surface layer characteristics. The time required for the impact voltage to decay to its original value appears to correlate with dipole orientation relaxation times obtained by dielectric constant and loss measurements.
