Abstract:
Provided are a contact sensitive device, a display apparatus including the same, and a method of manufacturing the same. The contact sensitive device includes an electroactive layer formed of an electroactive polymer having a plurality of nano pores and an electrode disposed on at least one surface of the electroactive layer. The electroactive layer has a β-phase structure and improved piezoelectricity without performing a stretching process or a polling process.
