In previous works, one sensor device, such as resistor, capacitor, and etc., can detect only one physical or chemical phenomenon. In order to acquire a lot of information of the outside world, many sensors are necessary. Thus, sensor system may become large. However, multi sensing operation is available for proposed sensor device, octagonal MOSFET type Hall sensor. This sensor can detect both magnetic field and temperature at the same time. As the results, we can realize that sensitivity of magnetic field and temperature are 16.3 mV/T and 0.053 mV/°C, respectively.","PeriodicalId":22504,"journal":{"name":"The Japan Society of Applied Physics","volume":"50 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87029817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we have controlled the molecular dipole in a vinylidene fluoride (VDF) oligomer thin film by applying electric field between micro-gapped comb-like electrodes during vacuum deposition. The dipoles in the normally oriented VDF oligomer were highly aligned to the applied electric field in in-plane direction. The pyroelectric IR sensors, fabricated by the oriented VDF oligomer thin film, exhibited the excellent performance even without the poling treatment after the film deposition. A voltage sensitivity of the sensor showed 1473 V/W at 1 Hz, which was much higher value than that of typical sensors applied with the post-poling (~ 200 V/W). The improvement of the sensitivity is considered to be caused by the reduction of injected charges on the poling treatment, which usually causes the suppression of the dipole fluctuations for temperature change.","PeriodicalId":22504,"journal":{"name":"The Japan Society of Applied Physics","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85591981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
