Abstract
【解決手段】圧電フィルム12はブリッジ状に撓ませて形成され、圧電フィルム12より短く形成された伸縮部材13で圧電フィルム12の両端を連結する。また、伸縮部材13と被検体との間に摩擦係数の小さい滑り部材14を設け、被検体に滑り部材14を介して伸縮部材13を当接させ、被検体の体動による伸縮部材13の伸縮動に追従して圧電フィルム12の撓みを変化させる。

Description
Claims (3)
- ブリッジ状に撓ませた圧電フィルムと、前記圧電フィルムより短く形成され前記圧電フィルムの両端を連結する伸縮部材と、前記伸縮部材と被検体との間に設けられた摩擦係数の小さい滑り部材とを有し、被検体に前記滑り部材を介して当接する前記伸縮部材の伸縮動に追従して前記圧電フィルムの撓みが変化することを特徴とする体動検知センサー。
- 請求項1に記載の体動検知センサと、前記体動検知センサーにより誘起された電荷を電圧信号に変換する差動増幅器と、前記差動増幅器で得られた電圧信号に基づいて前記被検体の体動の有無を判定する体動判定装置とを備えたことを特徴とする体動モニタリングシステム。
- 前記体動判定装置は、前記差動増幅器で得られた電圧信号をデジタル信号に変換してメモリに記憶することを特徴とする請求項1または2に記載の体動モニタリングシステム。
