It utilizes a custom design voltage controlled oscillator (VCO) with a tank-integrated capacitive sensor fabricated on a SiGe process. A change of the permittivity opposed to the sensor leads to a frequency shift which will be regulated by the PLL. Thus, the permittivity of a MUT is directly mapped to the resulting DC tuning voltage generated by the control loop. The sensor is configured and read-out by a microcontroller. The system is used to characterize solutions of ethanol-methanol mixtures with concentration differences of 5 percent around a mixture ratio of 50:50.","PeriodicalId":140312,"journal":{"name":"2015 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"400 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133578938","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 converter in this work can configure its resolution and sampling rate based on the input signal amplitude and frequency, respectively. Furthermore, it can automatically decide its configuration with the help of a novel, low-power automatic adaptation circuit. The converter has 10-bit resolution in high-resolution mode and 8-bit resolution in low-resolution mode. The bandwidth of the ADC is 100 kHz in low-speed mode and 20 MHz in high-speed mode.

A pair of inductivelycoupled coils operating at radio-frequency is extensively used to deliver electrical power to implants wirelessly. In this system, a power conditioning circuit is required convert the induced time-varying AC power harvested by the receiving coil to a stable DC power that is needed for powering circuits and sensors. Most existing power conditioning circuits require the induced voltage of the receiving coil to be significantly higher than the turn-on voltage of the diodes used in the rectifier for the efficient AC to DC conversion. This requirement results in larger coil size, shorter operating distance or more stringent geometrical alignment between the two coils. In this paper, a low-input-voltage wireless power transfer has been demonstrated. In this system, the opencircuit voltage of the induced 5 kHz AC input is as low as ~ 190 mV, and it has been converted to 5 V DC over a 25 kΩ resistor. Both the output voltage and the power drawn into the receiving coil can be regulated by the duty cycle of a control signal. The described system has the potential to reduce the size of the receiving coil, increase the operating distance between the transmitting and the receiving coil, and yet to achieve the desired DC output for implants.","PeriodicalId":140312,"journal":{"name":"2015 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"241 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115108968","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}

This sensor uses a microfluidic network in order to guide the liquid and drive the particles to analyze. Once properly calibrated this sensor should allow measuring the intrinsic dielectric properties of unknown liquid medium and even individual characteristics of flowing particles. Indeed characterizations done on small volumes of liquids with this device showed a good agreement with macro scale measurements done using a coaxial probe. To demonstrate its sensing capabilities, experiments with polystyrene beads have been first performed and compared with 3D electromagnetic simulations which show that potential high detection sensitivity can be expected. This opens attractive prospects in the frame of microwave dielectric spectroscopy for microanalysis of various dielectric particles like biological cells as example.","PeriodicalId":140312,"journal":{"name":"2015 IEEE Topical Conference on Biomedical Wireless Technologies, Networks, and Sensing Systems (BioWireleSS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123856016","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}

Selectivity to L-Glu was improved through implementation of self-referencing electrode and noise cancellation to minimize background noises and interference from other neurotransmitters. A microcontroller-based data acquisition system and a wireless transceiver were utilized to transmit measurements wirelessly to computer base stations and smart phones in real time.
