PROBLEM TO BE SOLVED: To provide a mat sensor device using a conductive cloth which can be a sensor having flexibility over a wide area and with which a touched state and a loaded state can be identified by one sensor without adverse influences caused by noise.SOLUTION: The mat sensor device comprises a mat sensor 6 which is configured in a three-layer structure from an insulator cloth 2 which is provided as an insulator with a non-conductive cloth, and front-side and rear side conductive clothes 1 and 3 laminated on front and rear sides of the insulator cloth 2, and which is provided in a mat shape, carpet shape or a sheet shape of cloth by adding electric wires to the front-side and rear-side conductive clothes 1 and 3, respectively, and making them functional as a capacitor. The front-side conductive cloth 1 is connected to a CPU 13 of a sensor detection circuit, and the rear-side conductive cloth 3 is connected to a ground side of a sensor detection substrate 7.COPYRIGHT: (C)2015,JPO&INPIT【課題】広い面積で柔軟性のあるセンサーとすることができ、一つのセンサーで、触れた状態と荷重をかけた状態とを、ノイズによる悪影響を受けないで識別できる導電性の布を使用したマットセンサー装置を提供すること。【解決手段】絶縁体として導電性のない布によって設けられた絶縁体布2と、その絶縁体布2の表裏のそれぞれに積層された表側及び裏面の導電性布1、3とによって三層構造に構成され、その表側及び裏面の導電性布1、3のそれぞれに電線を付け、コンデンサーの働きを持たせて布のマット状、カーペット状やシーツ状に設けられたマットセンサー6を備え、表側の導電性布1がセンサー検出回路のCPU13に接続され、裏側の導電性布3がセンサー検出基板7のグランド側に接続されている。【選択図】図1
