The proposed sensor is based on a conventional guided-wave optical pressure sensor using intermodal interference, with an added semi-closed space with a small hole under the bottom side of the diaphragm. By the addition of this semi-closed space, the sensor, unlike conventional sensors, can withstand high static pressure. When there is a sudden change in ambient pressure, pressure within the semi-closed space cannot quickly adjust due to the small hole that restricts fluid flow. So, pressure difference is induced on the diaphragm for a short while. Thus, the sensor shows a response only to changes in pressure, not to static pressure. We examined the step response of the sensor, that is, the output characteristics for sudden pressure change. The diaphragm dimensions of the fabricated sensor were 14 mmX14 mmX0.22 mm. Also, the volume of the semi-closed space was 14 mmX14 mmX1.8 mm, and the sectional area of the small hole was 93 umX25 um. In this experiment, the pressure in a 30 cmX28 cmX30 cm closed box, in which the fabricated sensor was placed, was suddenly increased by 0.78 kPa. Due to the pressure change, the output intensity decreased by approximately 20 % of the initial intensity level. Approximately 1.4 sec after the step-like change in pressure, output intensity returned to the initial level.", "subitem_description_type": "Abstract"}]}, "item_8_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "Integrated optics: devices, materials, and technologies 9 : 24-26 January 2005 : San Jose, California, USA. : Jan 2005, San Jose, CA", "subitem_description_type": "Other"}]}, "item_8_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "International Society for Optical Engineering, SPIE"}]}, "item_8_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "info:doi/10.1117/12.588457", "subitem_relation_type_select": "DOI"}}]}, "item_8_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright 2005 Society of Photo-Optical Instrumentation Engineers"}]}, "item_8_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_8_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA10619755", "subitem_source_identifier_type": "NCID"}]}, "item_8_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0277786X", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Endo, Yoshisumi"}], "nameIdentifiers": [{"nameIdentifier": "169444", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ohkawa, Masashi"}], "nameIdentifiers": [{"nameIdentifier": "169445", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sekine, Seishi"}], "nameIdentifiers": [{"nameIdentifier": "169446", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sato, Takashi"}], "nameIdentifiers": [{"nameIdentifier": "169447", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-26"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "5728_309-316.pdf", "filesize": [{"value": "938.7 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 938700.0, "url": {"label": "5728_309-316.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/31046/files/5728_309-316.pdf"}, "version_id": "25ee9aa0-ba64-4e12-92e1-6952435d0fd6"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Integrated optics", "subitem_subject_scheme": "Other"}, {"subitem_subject": "guided-wave optics", "subitem_subject_scheme": "Other"}, {"subitem_subject": "pressure sensor", "subitem_subject_scheme": "Other"}, {"subitem_subject": "diaphragm", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "conference paper", "resourceuri": "http://purl.org/coar/resource_type/c_5794"}]}, "item_title": "Guided-Wave Optical Pressure Sensor Responding only to Changing Pressure", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Guided-Wave Optical Pressure Sensor Responding only to Changing Pressure"}, {"subitem_title": "Guided-Wave Optical Pressure Sensor Responding only to Changing Pressure", "subitem_title_language": "en"}]}, "item_type_id": "8", "owner": "1", "path": ["457", "1827"], "permalink_uri": "http://hdl.handle.net/10191/31206", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-12-24"}, "publish_date": "2014-12-24", "publish_status": "0", "recid": "31046", "relation": {}, "relation_version_is_last": true, "title": ["Guided-Wave Optical Pressure Sensor Responding only to Changing Pressure"], "weko_shared_id": null}
