Abstract:
(EN) This piezoelectric element (10) formed from an elastomer is configured by alternately arranging first counter electrodes (11a) and second counter electrodes (11b) and interposing a dielectric layer (12) between a first counter electrode (11a) and a second counter electrode (11b). Each dielectric layer (12) comprises: a sheet-like dielectric part (13) which is formed from a dielectric elastomer; and a first common electrode (15a) which is formed from a conductive elastomer and connects the first counter electrodes (11a) with each other, or a second common electrode (15b) which is formed from a conductive elastomer and connects the second counter electrodes (11b) with each other. The first common electrode (15a) and the second common electrode (15b) are disposed so as to extend from one main surface to the other main surface of the dielectric part (13), and are respectively connected to the first counter electrodes (11a) and the second counter electrodes (11b) on a bonding surface (S) that is along the dielectric layer (12).
(FR) La présente invention concerne un élément piézoélectrique (10) formé à partir d'un élastomère qui est configuré en agençant en alternance des premières contre-électrodes (11a) et des secondes contre-électrodes (11b) et en interposant une couche diélectrique (12) entre une première contre-électrode (11a) et une seconde contre-électrode (11b). Chaque couche diélectrique (12) comprend : une partie diélectrique de type feuille (13) qui est formée à partir d'un élastomère diélectrique ; et une première électrode commune (15a) qui est formée à partir d'un élastomère conducteur et connecte les premières contre-électrodes (11a) l'une par rapport à l'autre, ou une seconde électrode commune (15b) qui est formée à partir d'un élastomère conducteur et connecte les secondes contre-électrodes (11b) l'une à l'autre. La première électrode commune (15a) et la seconde électrode commune (15b) sont disposées de manière à s'étendre d'une surface principale à l'autre surface principale de la partie diélectrique (13), et sont respectivement connectées aux premières contre-électrodes (11a) et aux secondes contre-électrodes (11b) sur une surface de liaison (S) qui se trouve le long de la couche diélectrique (12).
(JA) エラストマー製圧電素子(10)は、第1対向電極(11a)及び第2対向電極(11b)を交互に配置し、第1対向電極(11a)及び第2対向電極(11b)の間に誘電層(12)を挟むことによって構成されている。誘電層(12)は、誘電エラストマー製のシート状の誘電部(13)と、第1対向電極(11a)を互いに接続する導電エラストマー製の第1共通電極(15a)、又は第2対向電極(11b)を互いに接続する導電エラストマー製の第2共通電極(15b)とを備えている。第1共通電極(15a)及び第2共通電極(15b)は、誘電部(13)の一方の主面から他方の主面に達するように設けられるとともに、誘電層(12)に沿った接合面(S)にて第1対向電極(11a)及び第2対向電極(11b)にそれぞれ接続されている。
