The electret effect of kidney stones.
Surgically removed kidney stones were powdered and samples made from them were subjected to a d.c. field of 20-50 kV/cm whilst being heated at 1 degree C/min. The thermally stimulated polarization (TSP) spectrum obtained showed the dipolar nature of the material. Dipolar polarization in the stones was confirmed by other experiments.
