Electromechanical Film (EMFI, EMFIT, trademarks of Emfit Ltd) is a thin, flexible film that can function as a sensor or actuator. It is composed of a charged polymer coated with two conductive layers, making it an electret. It was invented and first made by Finnish inventor Kari Kirjavainen. It's voided internal … See more The base film is first made from bi-axially orienting a polypropylene film. It is created through a "film-blowing" process, in which the plastic is extruded using a film blowing machine in the shape of a tube. Through the process of See more EMFIT sensor film has a diverse range of applications due to it being flexible, durable, and sensitive to a wide range of frequencies. These properties are attributed to its … See more Sensor The film can be used as a sensor. As the film is charged, it creates an electric field. When pressure is applied to the film, the film's thickness is reduced and changes in the shapes of the individual voids in its structure occur. … See more Due to the thermal constraints faced by using polypropylene as base material, applications where high sensitivity is needed, long-term temperatures should be below 70 °C, which … See more
