연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

An electromechanic film intended for transforming electric energy into mechanical energy and transforming mechanical energy into electric energy. The film ( 1 ) is dielectric and formed of cells ( 3 ), the ratio of the height and width of which cells is between 3:1 and 1:3. By joining two such films together and controlling them in such a way that in the first film ( 1 ) the electric field strength decreases and in the second film ( 1 ) the electric field strength increases, a bending acoustic element is provided.

1. An electromechanic film for transforming electric energy into mechanical energy or transforming mechanical energy into electric energy in such a way that a voltage or a charge is conducted onto the surfaces of the film or a voltage or a charge is discharged from the surfaces of the film,wherein the film is dielectric and formed of cells, the ratio of the height and width of said cells is between 3:1 and 1:3, whereby, when one of the cells deforms, the pressure resisting the deformation inside the cell remains essentially unchanged. 2. The film accordi...
