MONITORING SYSTEM WITH PRESSURE SENSOR IN FLOOR COATING Russian patent published in 2020 - IPC A61B5/205 G08B21/04 

FIELD: medicine; monitoring systems.

SUBSTANCE: invention relates to a monitoring system. Disclosed is a monitoring system comprising a floor covering having a sheet-type pressure sensor installed therein or under it; a sensor control unit connected to a sheet-type pressure sensor, comprising an analogue-to-digital converter, a microcontroller connected to an analogue-to-digital converter for receiving a digital source signal. Microcontroller is configured to extract data by processing a digital source signal and generating a digital processed signal having a lower frequency range than said digital source signal. Digitally processed signal carries data extracted during processing of the digital source signal. System also includes a communication module connected to the microcontroller or built into it for reception of the digital processed signal. Communication module is configured to establish communication with one or more database servers and to transmit said retrieved data to one or more database servers. Said sheet-type pressure sensor comprises a ferroelectric polymer film containing a cellular structure of a polymer film which exhibits piezoelectric properties. Said film of ferroelectric polymer lies between the first electrode layer and the second electrode layer. At that, the first electroinsulating film is located on the second electrode, and the second electric insulating film is located between the first electrode and the screening electrode. Second electrode and the shielding electrode are connected to ground in order to shield the first electrode, which is the signal electrode of the sensor, from external electromagnetic interference.

EFFECT: invention provides more effective monitoring of the patient.
