EMF-kalvo (Electromechanical film) on ohut ja joustava elektreettimuovikalvo. Kal-volla voidaan mitata dynaamista voimaa. Tutkimuksessa rakennettiin EMF-kalvoon pe-rustuva voimamittausj\u00e4rjestelm\u00e4 voimistelun hyppylaudalle. J\u00e4rjestelm\u00e4ll\u00e4 pystyttiin mittaamaan hypp\u00e4\u00e4j\u00e4n ja hyppylaudan v\u00e4linen vertikaalinen reaktiovoimak\u00e4yr\u00e4. Voima-aikak\u00e4yr\u00e4st\u00e4 laskettiin vertikaalinen l\u00e4ht\u00f6nopeus, jota verrattiin liikeanalyysist\u00e4 saatuun tulokseen.
