TRIBOELECTRIC TRANSFORMER OF NON-ELECTRIC VALUES TO ELECTRIC SIGNALS Russian patent published in 2006 - IPC G01B7/00 

FIELD: measuring equipment engineering, namely, engineering of devices for measuring dynamic mechanical values, possible use for receiving and transforming various vibrations and mechanical movements of mobile mechanical systems and constructions in alarm systems.

SUBSTANCE: transformer contains external and internal coaxial conductors, between which layers of polymers are positioned coaxially. Also, external conductor is made in form of steel spiral. Also, layer closest to internal conductor is made of composition of porous and conductive polyethylenes with ratio 1:3÷1:5. another layer is made of ribbon high-polymer material, external diameter of which is 0,5÷0,7 of internal diameter of steel spiral.

EFFECT: increased sensitivity.
