Use of elektrets in low-current devices

摘要

On a elektret surface there is an electrode. An electrode close through loading with other electrode. The second electrode vibrates. The amplitude of a current in a contour is directly proportional to dielectric permeability of environment. The author suggests to insert into a backlash between a elektret and a vibrating electrode substance with huge dielectric permeability. The ceramics LSNO changes the permeability with frequency change a little. So it is possible to increase strongly a current in a chain.
