The sticker-form factor-mmID-tag has a total footprint of only 3.5 cm by 1.5 cm and is fabricated utilizing ultra-low cost inkjet-printed PCB technology and components. For the first time, a low-cost and ultra-compact antenna-on-package radar module is utilized for the reader system, to provide accurate microlocalization of the mmID tags in 2D space. One proof-of-concept tag was successfully localized at various steps of 5 cm from a range of 10 cm to 50 cm with a maximum deviation of 4.46 cm. The reader system also demonstrated the ability to detect the Angle-of-Arrival at a range of 15 cm in angular steps of 20° providing an angular coverage of ±40°. Lastly, the total power consumption of the mmID tag was measured at a mere 1.43 mW, allowing for long term usage of the tag in autonomous settings. This work potentially introduces a paradigm shift in the application of backscatter systems by introducing an affordable mmID-enabled real-time-microlocalization solution compatible with inconspicuous ubiquitous and wearable implementations.","PeriodicalId":358808,"journal":{"name":"2021 IEEE International Conference on RFID (RFID)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126535661","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}

By changing the tag's response to the Write command, the tag returns the subcarrier before returning the response specified in the protocol. In this way, a frequency calibration loop will be established between reader and tag. This method not only enables a low-power oscillator with a precise frequency to be integrated into a tag chip, but also enables flexible configuration of the frequency. The tag chip containing this idea is fabricated in SMIC 0.18 μm CMOS process with a die size of 850 μm × 850 μm. Measurement results show that the proposed novel method can realize the calibration of the subcarrier frequency, and the subcarrier frequency deviation is less than ±0.385KHz in the range of 40KHz-640KHz. With this accuracy, the tag can be allocated up to 78 subcarrier communication channels.","PeriodicalId":358808,"journal":{"name":"2021 IEEE International Conference on RFID (RFID)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131790962","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}

We can practice yoga on a specific mat for body fitness. It’s important to have the smart yoga mat, which can adjust the surrounding environment based on user’s physical activities on the yoga mat. For example, we can adjust the ambient light, music and temperature based on the yoga practitioner’s pose on the yoga mat.In this paper, we present RFitness, a system that can detect the fitness posture on the yoga mat. To do so, we can attach multiple commodity passive RFID tags on the yoga mat, such that the different fitness postures can affect different RFID tags. Based on the signal strength readings from all the tags, we can estimate the yoga fitness posture using the model-driven deep neural networks. We implement the prototype of RFitness using commodity passive RFID tags and USRP reader. Our extensive experiments show that RFitness can achieve the median accuracy of 0.96.","PeriodicalId":358808,"journal":{"name":"2021 IEEE International Conference on RFID (RFID)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124147943","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}

Conventional diagnostic tools involve X-Rays, MRI, CT imaging or, more commonly, the onset of the patient’s pain. Monitoring the health state of a prosthesis from the outside the limb can be accomplished by through-the-body wireless communication link. However, techniques for integrating a wireless sensor into orthopedic implants require a structural modification of the prosthesis. To overcome this limitation, a non-invasive way to augment a prosthesis with wireless monitoring capability is here proposed for the early detection of local tissue infection. The idea can be applied to an orthopedic fixation plate provided with holes, with no changes to its structure. The fixation bar is transformed into an RFID tag by exciting voltage gap into an unused screw hole. The electrical and geometrical parameters of the exciter enable a convenient two-steps tuning mechanism (coarse and fine) to adjust the working frequency. Preliminary simulations predicted a read range of more than 50 cm outside the body that is suited to an early and non-collaborative diagnosis in the emerging Personalized Healthcare.","PeriodicalId":358808,"journal":{"name":"2021 IEEE International Conference on RFID (RFID)","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116876463","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}
