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、
前記伸縮部材の一方端及び前記滑り部材の一方端に取り付けられ前記滑り部材が前記被検体側に向くように前記被検体の周囲に巻き付けて前記被検体に装着するバンドとを有し、
前記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。
