Description
前記各圧力検出部の周囲に、感圧導電性エラストマーの変形可能な領域を制限する剛体の外周カバー部を設け、該外周カバー部と圧力検出部との間に狭隙部を設けるとともに、前記外周カバー部の少なくとも一部が導電性を有し、圧力計測時の前記感圧導電性エラストマーの変形によって、前記狭隙部が埋まり圧力検出部と外周カバー部とが導通することを特徴とする。
図1に、本発明に係る圧力計測装置を例示する。複数の圧力検出部および各圧力検出部に対応する印加電極と出力電極から構成される圧力検出ユニット1が、保護カバー2を介して枠体3によって基体4に固定されている。例えば、タイヤの計測においては、タイヤを枠体3の上を走査することで、圧力検出ユニット1の各圧力検出部が圧力を感知し、タイヤの接地圧を計測することができる。

- 印加電極、出力電極および計測面を有する感圧導電性エラストマーから構成される圧力検出部を、一定間隔に平面状に複数配列し、該複数の圧力検出部出力を多次元情報として取り出す圧力計測装置であって、
前記各圧力検出部の周囲に、感圧導電性エラストマーの変形可能な領域を制限する剛体の外周カバー部を設け、該外周カバー部と圧力検出部との間に狭隙部を設けるとともに、前記外周カバー部の少なくとも一部が導電性を有し、圧力計測時の前記感圧導電性エラストマーの変形によって、前記狭隙部が埋まり圧力検出部と外周カバー部とが導通することを特徴とする圧力計測装置。 - 前記圧力計測装置がタイヤの接地圧力計測用として用いられ、タイヤのトレッドパターン内の1つのブロックに対しても、複数の前記圧力検出部が接することを特徴とする請求項1記載の圧力計測装置。
