Parameters of constructive interference such as time-shift and magnitude also play a crucial role in creating effective haptic feedback at the point of contact. However, Propagation of standing waves along deformable surfaces, such as Gorilla glass, quickly attenuates vibration signals, drastically reducing the efficiency of perceivable haptic signals. In order to facilitate signal propagating parameters and create HD haptics, it is necessary to use materials that effectively transfer vibration signals within a mobile device. To minimize attenuation, a display overlay pouch sealed with liquid can be used. In this paper we demonstrate the ability to generate a virtual tactile exciter as the result of the interference maximum of two Tectonic actuators affixed to the display of a Microsoft Surface Go tablet as well as to the display overlay pouch sealed with liquid. For both the liquid mediator and glass surfaces we revealed high similarity in the trend of peak-to-peak values of interference maximum indicated by Excel’s LINEST function (0.9805). We also found that the interference maximum in the pouch sealed with liquid to be 19.06dBV greater than that of the tablet. The results can be used for creating HD haptics and applications.","PeriodicalId":6710,"journal":{"name":"2019 IEEE SENSORS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89867999","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}

Firstly, the effects of sensor size (L), the location of detectors (D) and the cover height (H) on the performance are deeply analyzed by means of the proposed theoretical model. Six types of micro thermal convective accelerometers with parallel-stack detectors are fabricated by means of the CMOS compatible fabrication process to enhance the sensitivity. Both the theoretical and experimental results demonstrated that larger sensor size and cover height could improve the sensitivity of MTCA. Additionally, increasing sensor size would lead to a shift of the normalized optimal distance to the heater side. By means of the structure optimization and the parallel-stack method with three pairs of detectors, a MTCA with the sensor length of 1600μm is achieved with an outstanding sensitivity of 7075μV/g (gain=1) and normalized sensitivity/power (S/P) ratio of 201.4 μV/g/mW, which is twenty-fold larger than the state of art.","PeriodicalId":6710,"journal":{"name":"2019 IEEE SENSORS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89915492","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}

This greatly improves the stability and eases a subsequent implementation as application specific integrated circuit (ASIC). Measurement results with a prototype PCB implementation show a full scale of more than 100 kPa or 50 μl/s and a RMS noise of the readout circuit lower than 320 μV over the measurement bandwidth of 500 Hz corresponding to a resolution better than 200 Pa or 170 nl/s.","PeriodicalId":6710,"journal":{"name":"2019 IEEE SENSORS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88900026","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}

Monitoring the blade deflection enables the possibility to avoid tower striking, reduce maintenance costs and optimize control parameters. The system consists of one or multiple nodes for motion tracking using inertial measurements and a stationary receiver. The nodes are designed to continuously measure acceleration and angular rate. The raw measurements are transmitted periodically to a base station where further signal processing takes place. The sensor node is developed for application inside a wind turbine blade without accessibility to external power supply. Therefore, an electromagnetic energy harvester has been developed to make use of the wind turbine blade rotation. The requirement of low power consumption is fulfilled by using the latest MEMS sensor technology in combination with an optimized wireless communication protocol based on IEEE 802.15.4 standard and a low power microcontroller. A 100Hz sample rate of the inertial measurement unit (IMU) results in a wireless data stream of 10.8kBits−1 and a total power consumption less than 1.5mW. The blade trajectory can be reconstructed using an algorithm based on Extended Kalman Filters.","PeriodicalId":6710,"journal":{"name":"2019 IEEE SENSORS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86223431","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}

An innovative electrophoretic deposition approach is used to deposit a thin and conformal carbon nanotube coating on a nylon-polyesterspandex knitted fabric. The carbon nanotube coating is chemically bonded on the surface of the fibers and creates an electrically conductive network. As a result, these sensors display piezoresistivity; that is, the resistance of the sensor changes due to mechanical deformation. First, the sensing response under tension is characterized using mechanical testing equipment. The sensors are then integrated into compression knee sleeves to investigate sensing response due to knee flexion. When the sensing fabric is stretched, an increase in electrical resistance is observed due to change in the microstructure of the knitted fabric and because of the piezoresistivity of the coating. Under knee flexion, a resistance change of over three thousand percent is detected. The carbon nanotube coated knitted fabrics as flexible stretch sensors have wide-ranging applications in human motion analysis.","PeriodicalId":6710,"journal":{"name":"2019 IEEE SENSORS","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87048966","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}
