This paper presents a fully printed and soft capacitive pressure sensor realized through a two-dimensional interdigitated capacitor. The sensor transduces applied pressures through a fringing electric field interacting with a deformable elastomer. The deformable elastomer consists of either pure polydimethylsiloxane (PDMS) or a layered PDMS/BaTiO3 structure. A 10 mm overlaid layered structure is created by depositing six alternating layers of a Barium Titanate-PDMS mixture and pure PDMS, followed by a 4 mm PDMS layer on the printed electrode. Multiple tests using standardized pressure and capacitance measurements have been performed to measure and compare the sensitivity between pure PDMS and PDMS/BaTiO3 layered configuration. The capacitive response shows that the layered PDMS/BaTiO3 device enhances the sensitivity for pressures less than 1 kPa by approximately 10x. This work demonstrates the potential of a printed electronic sensor in measuring small-scale pressure variation using inexpensive and simple fabrication methods.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"14 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90143353","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}

To provide reliable sensors that can withstand industrial applications, we have developed a soft and thin-film tactile sensor capable of detecting tri-axis force components including normal and shear forces. The thickness of the sensor is 5.5 mm, and the sensor can be easily attached on an end-effector. Two layers of capacitive-sensing-electrode arrays sandwiching an elastomer layer of 2-mm spatial resolution are embedded in soft material, and output signals are distributed. To measure the external force vector, center-of-distributed-signal calculation was conducted. Our sensor exhibited linear behavior within 0.1 to 10 N for normal force and 0.1 to 4 N for shear force. With high reliability, sensor sensitivity did not change over ±10.0% even after one million repetitive keystroke cycles and one million repetitive shear-movement cycles. To determine the sensor’s effectiveness for manipulation tasks, a grasping-force control experiment was conducted using sensor signal feedback, and multiple local-shear-force vectors were successfully calculated using area-divided methods.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"22 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73415794","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}

OSA is a condition where patients suffer from irregular sleep patterns due to difficulty in breathing. A possible treatment of OSA is use of mandibular advancement devices (MADs). In this manuscript, we present a smart MAD that can monitor intraoral EEG signal. The device acquires intra-oral EEG signal from the mouth-roof. So far very limited research is done in the area of intra-oral EEG monitoring. The proposed smart MAD consists of a MAD, three flexible gold EEG electrodes and an EEG measurement system implemented on a flexible polymide substrate. The measurement system is battery operated and sends EEG data wirelessly using a BLE 5.0 transceiver. The system is validated by acquiring intra-oral EEG signal for \"eye-open\" and \"eye-close\" activities of five volunteers. The frequency domain analysis of the intra-oral EEG signal clearly shows that \"eye-open\" and \"eye-close\" activities can be detected from the data. In future, this smart MAD will be used to acquire intra-oral EEG data during sleep for OSA patients and determine sleep stages.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"49 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76382366","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}
