Such an application demands an ultra-low power architecture fur an increased overall lifetime of the sensor node. The asynchronous circuit architecture and its subthreshold logic implementation both significantly reduce the leakage power dissipation by factor three.

Lossy materials do not significantly reduce the effective quality factor, which is as high as 30,000 at 1.2 GHz, of the sensor.

In the application, IR-UWB radar systems with a low center frequency are commonly used to guarantee good penetrability. These systems transmit pulses with nanosecond width. So they have relatively low range resolution, which in turn impacts their performance of detecting the vital signs. To cope with the problem, a dual-frequency IR-UWB radar system is developed. The system combines two IR-UWB radars with different center frequencies, namely 400 MHz and 270 MHz, and utilizes time division multiplexing, composite antenna array and novel signal processing techniques to ensure its compatibility and performance. Experimental results are also presented to show the system's advantages over single-frequency IR-UWB radar systems.","PeriodicalId":341652,"journal":{"name":"2014 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129362565","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}

One of the main problems is that a tri-axis accelerometer sensor should be mounted at a different position such as rear waist for accurate energy expenditure (EE) estimation whereas an electro-cardio-gram (ECG) sensor should be separately mounted at a chest position for accurate heart rate (HR) estimation. In this paper, we newly design a wireless waist-mounted vital sensor node for both EE and HR estimations. First of all, to select a microcontroller suitable for the data processing in the vital sensor node, we numerically compared three microcontrollers in terms of energy consumption required for the vital data processing. The comparisons showed that LPC1768 is the most power-efficient candidate, so then we designed and implemented a prototype vital sensor node using LPC1768.","PeriodicalId":341652,"journal":{"name":"2014 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131814152","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}

However, the received signal may be corrupted when there is a random motion if handheld UWB radar is used, especially when the amplitude of motion is higher than that of the thoracic motion. In this paper, a random motion cancellation method using an embedded system is proposed for recovering the real vital signs similar to image stabilization in optical cameras. The proposed embedded system is attached to the receiving antenna and used to collect the data of motion acceleration. The correlation between the data collected by the UWB system and embedded system is analyzed and a Finite Impulse Response (FIR) model considering the time delay between these two systems is developed as well. Experiments show that the respiration rate of a subject can be accurately recovered by motion cancellation method even in the presence of a high-amplitude motion of the receiver.","PeriodicalId":341652,"journal":{"name":"2014 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"713 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132508265","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}
