Printable Emfit film

Screen Printable Electroactive Ferroelectret Film

​

Emfit-PET™ is screen printable, electro-active polymer (EAP) sensor film. Its outer layers are thin polyester films and the core is a high-pressure gas-expanded cellular structure that has permanent electric charge injected into the material by corona charging in a high electric field.

 

The Emfit-PET -film was developed for customers that have electrode screen printing design and printing capabilities and can take the Emfit film in a basic form and refine it to a finished sensor product for custom applications. The Emfit-PET –film can have the electrode patterns screen printed directly onto the film with standard screen printing machinery and inks (silver paste, graphite) instead of using separate electrode layered sheets. The film can be used also with electrode layers arranged onto printed circuit boards (PCBs).
