PROBLEM TO BE SOLVED: To provide a sensor with an impact absorbing function which can detect a state of a person to be protected and has an impact absorbing function capable of absorbing impact on the person to be protected.SOLUTION: The sensor 1 with an impact absorbing function includes: a high attenuation layer 5 to absorb impact which the person M to be protected receives when toppling down or falling down a flexible sensor film 20 which is arranged on the surface side of the high attenuation layer 5 and includes elastomer or flexible cloth a plurality of electrodes 01X-24X and 01Y-18Y arranged via at least a part of the sensor film 20 and a plurality of detecting units A0101-A2418 set corresponding to the arrangement of the plurality of electrodes 01X-24X and 01Y-18Y. The sensor 1 also includes a sensor body 2 which outputs a quantity of electricity corresponding to the detecting units A0101-A2418 from the electrodes 01X-24X and 01Y-18Y.COPYRIGHT: (C)2011,JPO&INPIT【課題】保護対象者の状態を検出可能であり、保護対象者が受ける衝撃を吸収可能な衝撃吸収機能付センサを提供することを課題とする。【解決手段】衝撃吸収機能付センサ1は、転倒または転落の際に保護対象者Mが受ける衝撃を吸収する高減衰層5と、高減衰層5の表側に配置され、エラストマーまたは伸縮性を有する布を含む柔軟なセンサ膜20と、センサ膜20の少なくとも一部を介して配置される複数の電極01X~24X、01Y~18Yと、複数の電極01X~24X、01Y~18Yの配置に対応して設定される複数の検出部A0101~A2418と、を有し、検出部A0101~A2418に対応する電気量を電極01X~24X、01Y~18Yから出力するセンサ本体2と、を備える。【選択図】図3
