DEVICE TO PRODUCE ELECTRIC ENERGY BY DEFORMATION OF PIEZOELECTRIC MATERIAL UNDER ACTION OF OUTER HYDROSTATIC PRESSURE

摘要

FIELD: electricity.;SUBSTANCE: invention relates to devices generating electric energy. The device for generation of electric energy comprises a solid body and two covers at the ends, which are deformed under action of hydrostatic pressure. Inside the body there are piezoelectric sensors installed tightly, onto piezoelectric material of which a force is transferred from hydrostatic pressure via covers. Under action of this force piezoelectric material of sensors is deformed, and electric voltage is generated. Some sensors inside the body are connected to each other in series, to increase voltage, creating blocks, and blocks themselves, for increasing of electric current are connected to each other in parallel into a system (8), the output voltage of which (U₁) is also an output voltage of the device. This voltage is sent to terminals (7) through a switch (6).;EFFECT: invention makes it possible to create an electrical energy generator with control of value of produced electric voltage without additional devices.;2 dwg
