Digital radiography (DR) enables non-destructive evaluation of SAW welds. However, data provided by most industrial DR imaging systems suffers from low resolution and contrast, high noise background which makes manual inspection a challenging task. Unlike conventional methods aiming at detection of weld defects, We focus on pixel-wise extraction of both welds and defects out of the radiographic frames via semantic segmentation. Experiments suggest that our method yields quality pixel-level inferences: the size, form and positions of the welds and defects. This could be more meaningful for further evaluations where the relative positions and morphological feature of welds and defects are needed.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"159 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":"74378769","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}

A biosensor for the detection of neuropeptide Y (NPY), a marker of stress, has been designed and tested for operation in a flexible microneedle form factor. The biosensing principle used is affinity binding of NPY to a DNA aptamer-functionalized electrode. A gold microelectrode was functionalized by formation of a self- assembled monolayer (SAM) of a thiol-modified NPY-binding aptamer and poly(ethylene glycol) methyl ether thiol (PEG). The sensors were evaluated by cyclic voltammetry and electrochemical impedance spectroscopy, resulting in a response to NPY over 400 pM to 200 nM when tested in KCl and K3[Fe(CN)6]/K4[Fe(CN)6], and PBS.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"6 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":"82499025","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}

A dynamically balanced out-of-plane resonator is proposed to achieve small frequency mismatch between in-plane and out-of-plane modes, with high quality-factors (Q-factors). An innovative dual-mass structure was designed to reduce the torque applied to the supporting substrate in the out-of-plane mode, and thus increased the Q-factor. The concept was confirmed by both numerical simulation and the measurement of a real device. The finite element analysis (FEA) study showed the frequency mismatch as small as 6.3 Hz.

The experimental characterization revealed that the mismatches of resonant frequencies and Q-factors were 106 Hz and 790, respectively.","PeriodicalId":6775,"journal":{"name":"2021 IEEE Sensors","volume":"94 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":"75453592","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}

The proposed model is introduced on the basis of combining the theoretical equation with the approximate form factor based on the measured data. In order to create the model, we fabricate several types of the MEMS capacitive accelerometers with the different structure parameters such as the etching hole area, the perforated proof mass area, and the gap. The calculation results show that the damping constant b by the proposed model is in accord with the measured b. Moreover, the Brownian noise BN calculated by the proposed model is also consistent with the measured BN.

The results showed that the sensor output to each gas increased by 26.0% for ammonia, decreased by 54.3% for acetic acid, and did not change for ethanol when a voltage of 50 V was applied.
