THIN-FILM FLEXIBLE ELECTRIC HEATER Russian patent published in 2010 - IPC H05B3/18 

FIELD: electrical engineering.

SUBSTANCE: invention relates to flexible electric heater generating temperatures approximating to 150°C, which can be used to maintain preset temperature in spacecraft onboard instruments space, survival suits etc. Proposed heater comprises resistive element arranged between two flexible heat-resistant insulating films and is furnished with current conductors. Aforesaid resistive element represents a polymer film with metallised multi-layer coating made by ion-plasma deposition, thickness of every layer varying from 20 to 100 nm. Said metallised coating features specific electrical resistance making about (300-55) 10^-8 Ohm·m and thickness of 3 to 25 mcm.

EFFECT: heating of various-shape objects.
