In order to have a compatible device for applications of relative humidity measurement, the humidity sensors must be made in small size, low power consumption, low cost, and high performance. Microelectromechanical systems (MEMS) humidity sensors are well developed and have high efficiency. However, it has problems such as high damping coefficient and low sensitivity. Thus, this research will focus on design, analytical modeling and simulation of the MEMS resonator sensor for humidity detection. Mathematical equations that model the behavior of the device and optimize it through finite element analysis (FEA) simulation to investigate device characteristics such as spring constant, resonant frequency, air damping, quality factor and mass sensitivity. The device will be designed based on standard PolyMUMPs process technology. Electrothermal actuation method will be used to actuate the device and capacitive sensing technique to measure the output voltage. The effect of changes in length and width of the beam on spring constant and resonance frequency are investigated. The spring constant is found to be decreasing when the length of the beam increases and increasing when the width of the beam increases. On the other hand, resonance frequency is found to be decreasing when the length increases and increasing when the width of the beam increases. The effect of air damping also has been studied. It is found that the damping coefficient decreases where the number of holes and radii of holes increases. Analytical and simulation results of frequencies showed good agreement within percentage difference of 0.04 -1.23%.","PeriodicalId":223737,"journal":{"name":"2020 IEEE Sensors Applications Symposium (SAS)","volume":"391 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115914627","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 the present study, visualization and data analysis methods for understanding the entire cell-level intracellular transport in a living cell is suggested, by applying computer vision techniques to the cell images collected on the camera image sensor.

CoAP (Constrained Application Protocol), combined with DTLS (Datagram Transport Layer Security), provides security to IoT/Fog applications. However, processing times need to be considered when using this combination due to IoT/Fog environment constraints. Our work presents a CoAP with DTLS application and analyzes the performance of Raspberry Pi 3 during DTLS handshakes, data encryption and data decryption with the most relevant cipher suites. The performance of confirmable and non-confirmable CoAP POST requests is also measured and discussed in our work. We discovered that cipher suites that use RSA as an authentication method on handshake are slightly faster than cipher suites that use ECDSA, while symmetric key encryption with AES256(128)GCM are 40% faster than AES256(128) default modes. Our study also suggests CoAP modifications to obtain higher efficiency, and it might help future IoT/Fog application developers to understand CoAP and DTLS union, providing an application example and performance metrics.","PeriodicalId":223737,"journal":{"name":"2020 IEEE Sensors Applications Symposium (SAS)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134011145","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 printer, a paper-cutting machine, and a laminator were used to create electrodes and hydrophobic barriers. With the combination of different paper crafting techniques, electrodes as well as microfluidic channels could be fabricated. For demonstration, a paper-based microfluidic device with impedance readout is introduced in this study. Laser printed polyester particles from a toner were used as an adhesive interface for a metal film transfer process, resulting in a defined electrode pattern. A cut pattern produced by a paper-cutting machine was used to produce distinct hydrophobic barriers, which constituted microfluidic channels and sample reservoirs. The application was demonstrated by developing flexible interdigitated electrodes (IDEs). The developed IDEs could be used to determine chemical concentrations of electrolyte and glucose. The presented fabrication method is suitable for rapid, low-cost production of flexible disposable sensors from digital files using well-known crafting practices.","PeriodicalId":223737,"journal":{"name":"2020 IEEE Sensors Applications Symposium (SAS)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128690938","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}
