Description
及び高速なダイナミクス(dynamics)により、触覚フィードバックのための満足のいく解決策を与えるものである。しかしながら、このようなアクチュエータを消費者製品に機械的に組み込む及び搭載することが厄介なものであることが多い。また、モノリシック圧電セラミックスは、通常、非常に壊れ易くもろいものであり、また、そのセラミックスを取り入れた電子装置を落とした場合、又は、その電子装置が他の類似した力若しくは応力を受けた場合に、壊れうる。時々、モノリシック圧電セラミックスを商品化製品に組み込むことが困難でありうる。
かしながら、通常のタイプとは対照的に、触覚タイプは、そのタイプにタッチするユーザに触覚フィードバックを提供するために任意の好適な手法によりシミュレートすることが可能なものである。また、複合物圧電アクチュエータが触覚タイプの形状で形成されるときには、このタイプはまた2つの部品の間におけるシール材として機能することができる。例えば、タッチスクリーンを有する触覚タイプを用いる場合には、この触覚タイプは、タッチ面の層とその下に位置する液晶ディスプレイ(LCD)といったようなディスプレイ装置との間におけるシール材として機能する。
広がる他の圧電構造と電気的に繋がるように、デザインされている。
」構成であって、図4に示された構成である。具体的には、複数の圧電ファイバー又は圧電ロッドが、3次元xyzポリマーマトリックス内においてy軸に沿って1次元に配置されている。これらの成分のうちの各々のみによっては通常は実現不可能な性質が、これらの材料を様々な接続パターンの環境内においてマイクロレベル又はマクロレベルで取り付けることによって、達成可能である。
