Abstract

"ATUADOR DE TENçãO EMBALADO". Uma montagem de atuador modular inclui uma ou mais chapas ou elementos de material eletro-ativo ligados a uma folha de eletrodo, de preferência por meio de um polímero estrutural de modo a formar um cartão. O cartão é selado, e pode em si mesmo constituir um dispositivo prático, como, por exemplo, uma palheta, um misturador, um agitador, uma alavanca, um impulsor ou sonar para contato direto com um sólido ou imersão em um fluido, ou pode ser ligado por meio de um adesivo duro de modo a fazer um acoplamento mecânico superfície à superfície com uma peça de trabalho sólida, um dispositivo, uma máquina de substrato ou amostra. O polímero estrutural provê uma rigidez à curvatura de tal forma que a chapa fina não se deforme ao seu ponto de criação, e uma rigidez mecânica tal que forças de cisalhamento sejam eficientemente acopladas a partir da chapa para a peça de trabalho. Em outras modalidades, o cartão pode incluir elementos de circuito ativo por meio de sinais de chave, de força ou de processamento, e/ou elementos de circuito passivo para sinais de filtragem, de conjugação ou de amortecimento, de modo pouca ou nenhuma conexão para um circuito externo é requerida. A montagem de atuador pode ser fabricada em quantidade, a fim de prover um atuador versátil com características mecânicas e de atuação uniformes, que introduz uma carga de massa insignificante para a peça de trabalho. Os cartões em si podem ser dispostos como atuadores mecânicos independentes, ao invés de como atuadores de transferência de tensão, nos quais a tensão induzida modifica a posição do cartão. Várias disposições de cartões com pino ou montado em balanço podem atuar como um impulsor, um recurvador, ou outro atuador de motivo, e estruturas, como, por exemplo, foles energizados podem ser formados diretamente ao se dobrar um ou mais cartões padronizados adequados."PACKED TENT ACTUATOR". A modular actuator assembly includes one or more plates or elements of electro-active material attached to an electrode sheet, preferably by means of a structural polymer to form a card. The card is sealed, and may itself be a practical device, such as a pick, mixer, stirrer, lever, impeller or sonar for direct contact with a solid or immersion in a fluid, or may be bonded by a hard adhesive to mechanically surface to surface coupling with a solid workpiece, device, substrate or sample machine. The structural polymer provides a stiffness to the curvature such that the thin sheet does not deform to its point of creation, and a mechanical stiffness such that shear forces are efficiently coupled from the sheet to the workpiece. In other embodiments, the card may include active circuit elements by means of key, force, or processing signals, and / or passive circuit elements for filtering, conjugating, or damping signals, so little or no connection to each other. An external circuit is required. Actuator mounting can be manufactured in quantity to provide a versatile actuator with uniform mechanical and actuation characteristics that introduces an insignificant mass load to the workpiece. The cards themselves can be arranged as independent mechanical actuators, rather than as voltage transfer actuators, where induced voltage modifies the position of the card. Various pin or swing-mounted card arrangements can act as a pusher, bend, or other motive actuator, and structures such as powered bellows can be formed directly by folding one or more suitable standard cards.
