In the book is clarifid the essence of the electret effect and its main parameters are defied. Brief historical information is also given. Dependencies for the electric filds of electrets and forces which occur in the structure electrode electrodes are presented. The presentation of the electrical filds of the electrets and the forces of interactions is done by normalized to the relative permittivity of the dielectrics thickness of electrets.
The percolation model is also considered together with the well known phenomenological and injection models. Suffiient place is devoted to the use of electrets as two of the main groups of applications are discussed electret transducers at which due to movement of one of the electrodes under the inflence SUMMARY 233 of mechanical effect an alternative current or pulse is generated in the external circuit (transformation of mechanical energy into electrical) and the other way about under the inflence of external electric fild one of the electrodes makes a mechanical movement (transformation of electrical energy into mechanical) and the applications based on direct application of electric filds of electrets (includ ing in medicine).
