DISTRIBUTED PIEZOELECTRIC POWER CONVERTER Russian patent published in 2018 - IPC G01L1/16 

FIELD: measurement.

SUBSTANCE: invention relates to measuring technology and can be used in various industries (mining, oil and gas, machine building, chemical, etc.) for remote indication and recording of mechanical forces, in particular for diagnosis and monitoring of stress-strain state of rock massif in vicinity of capital, cleaning and preparatory mine workings, as well as for technospheric and natural emergencies. Claimed distribution piezoelectric force transducer comprises an n-e number of piezoelectric force converters consisting of the same elements: two piezoelements of direct action with poles of sequential direction, power supply unit, electrodes included in electrical circuit, display device in form of transparent housing with capacitor in it with electrically conductive particle placed between its plates and optical fibers for discrete information transfer, wherein piezoelectric force transducers are connected in single optical channel in series - output of light conductor of previous power converter with introduction of subsequent converter, and conductive particles in capacitors are made different in size for each converter.

EFFECT: technical result consists in carrying out distance measurement of deformation of mechanical forces at n points due to use of discrete optical transmission of information by light guides along single line with significant reduction of optical fibers, and also in simplifying design and reducing laboriousness of installation work.
