In order to use this system for a collaborative brain-computer-interface (BCI) multiple EEG sub-systems with a common visually and auditory evoked potential (VEP/AEP) stimulator, a video camera and a PC, all connected to a WLAN, are required. Since each of the components has its own software clock typically based on a quartz crystal, a difference in skew and offset between all system components is induced after a few seconds from their cold start; this is due to the quartz instability of ±50 ppm. To evaluate evoked potentials of different test subjects synchronous in time in a group experiment scenario, it is necessary to implement a common time reference among the entire system. To achieve time synchronization without modifying the existing hardware/software a novel synchronization add-on, and a synchronization center based on Bluetooth were implemented and experimentally evaluated.","PeriodicalId":13244,"journal":{"name":"IEEE SENSORS 2014 Proceedings","volume":"222 1","pages":"2250-2254"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75629571","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 modulator adopts a 2-0 multi-stage noise-shaping structure (MASH2-0), which was studied by system-level modeling and hardware implementation using an FPGA. The study shows that the MAH2-0, like the MASH2-2, is inherently stable, has a high overload-input level and high dynamic range compared to single-loop EM-ΣΔM. However, the MASH2-0, with its simpler implementation, achieved a higher dynamic range and better signal-to-noise ratio than a comparable MASH2-2 and fourth-order single-loop EM-ΣΔM. A capacitive MEMS accelerometer was designed and employed in this system. Within a bandwidth of 1 KHz, the sensor achieved a noise-floor level of -130 dB, a full scale of ±20g acceleration, and a bias instability of 20 μg for a period of three hours. The investigation confirms the concept of the MASH2-0 structure and shows its potential as a closed-loop interface for high-performance capacitive MEMS inertial sensors.","PeriodicalId":13244,"journal":{"name":"IEEE SENSORS 2014 Proceedings","volume":"58 1","pages":"1780-1783"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75777670","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 different RFID alternatives are described with their pros and cons. The benefits and limitations of battery-free wireless sensors based on RFID technology are presented. Subsequently, the paper describes the design of an UHF RFID integrated circuit (IC) designed to harvest and store the power from an incoming RF signal in order to supply low power analog or digital sensors. The IC has been implemented using a low cost 0.35 μm CMOS process and it incorporates a serial peripheral interface (SPI) in order to communicate with the sensor. Battery-free wireless operation for industrial monitoring using the designed IC has been demonstrated by implementing two wireless sensors that monitor both temperature, using a thermistor, and pressure, using a commercial digital sensor. The wireless temperature sensor shows an error below ±1°C from -25°C to 105°C, whereas the pressure sensor error is below ±2 mbar from 325 to 1000 mbar. A battery free communication range of 1.5 meters is demonstrated for both sensors using a 2-W effective radiated output power reader.","PeriodicalId":13244,"journal":{"name":"IEEE SENSORS 2014 Proceedings","volume":"29 1","pages":"1499-1502"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78228807","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}

Presented herein is a flexible scheme to screen lysis protocols for active enzyme extraction.

The gas flows were controlled by an automated system that also controlled the environmental conditions and mixed the gases delivering them onto the measurement cell where three small commercial sensors were placed.

The proposed solution is based on a thermo-harvesting module that scavenges the energy required to operate from the target device under monitoring. The heat-sink provides optimal thermal dissipation while the SoC underneath provides feedback on the temperature. The thermal gradient between the chip and the environment is converted into electrical energy that supplies the wireless interface to send a beacon message to a receiver. The packet rate is directly related to the temperature of the target device by means of the efficiency curve that characterize the thermo-harvesting module. We designed the proposed SoC architecture and we proved the concept using commercial devices. We validated our approach comparing simulated results with real experiments.
