PROBLEM TO BE SOLVED: To provide an occlusal force detection device capable of outputting a wide range of highly accurate information about an occlusion analysis, and to provide an information processing device.SOLUTION: A sensor sheet 102 for detecting occlusal force which is more inexpensive and has higher resolution than in the conventional technology is achieved by providing an X-electrode sheet 204 and a Y-electrode sheet 203 provided with a plurality of electrode wires 202 on both faces of an organic piezoelectric film 201. An information processing device 104 performs integration operation processing in each intersection point to address information of each intersection point outputted by an occlusal force detection device having the sensor sheet 102 using an organic piezoelectric film 201, and raw data including data based on a signal showing a change in occlusal force, and creates data of the occlusal force. The information processing device 104 which can measure occlusal force on a time base can be achieved by having integration operation processing.COPYRIGHT: (C)2015,JPO&INPIT【課題】咬合分析に関し高精度且つ多岐に渡る情報を出力できる咬合力検出装置と、情報処理装置を提供する。【解決手段】有機圧電フィルム201の両面に、複数の電極線202を設けたX電極シート204とY電極シート203を設けることで、従来技術と比べて低コストで高分解能の、咬合力を検出するためのセンサシート102を実現できる。情報処理装置104は、有機圧電フィルム201を用いたセンサシート102を有する咬合力検出装置が出力した、交点毎のアドレス情報と、咬合力の変化を示す信号に基づくデータを含む生データに対し、交点毎に積分演算処理を行って、咬合力のデータを作成する。積分演算処理を有することで、時間軸上の咬合力を精緻に測定できる、情報処理装置104を実現できる。【選択図】図1
