Hybrid-powered RFID sensor networks
Proceedings of the 7th ACM Conference on Embedded Networked Sensor Systems, 2009RFID sensor networks comprising batteryless devices that are passively powered by RFID readers present exciting possibilities for ubiquitous computing applications. They require minimal maintenance, are cheap to manufacture and have small form factor. However, their lack of autonomy due to the need for constant power from an RFID reader hinders their ...

Optimization of RFID Sensor With Frequency Modulation
IEEE Sensors Journal, 2016Sensing capabilities of radio frequency identification (RFID) have recently been investigated both theoretically and experimentally. Frequency-modulated sensors utilize the modulation frequency for carrying sensor information when interrogated by a reader device.

RFID Multiprobe Impedance-Based Sensors
IEEE Transactions on Instrumentation and Measurement, 2010In this paper, a passive multiprobe sensor using conventional UHF radio frequency identification (RFID) tags is presented. The RFID link between the reader and the tag is analyzed from a general point of view by means of reciprocity principle, to obtain a compact and explicit expression of the response of RFID tags that can be exploited in sensing ...

Using RFID technology for sensor purposes
ICECom 2013, 2013In this paper we present new potentials of RFID technology in sensor systems. The working principle so far relied on measuring differences in the power received from the tag based on the environment conditions that surrounded the tag. Sensor systems with larger accuracy can be realized if tags with I2C interface are used, e.g.

IEEE Microwave and Wireless Components Letters, 2013
A cost-effective integration of passive UHF RFID tags and sensors is still a challenge. In such a field, authors have already proposed a label-type multi-antenna Sensor-Tag, an RFID device accepting as input a generic sensor and allowing the transmission of the measured data towards a standard RFID reader.

Passive multivariable RFID pH sensors
2011 IEEE International Conference on RFID-Technologies and Applications, 2011Sensing of pH with single-use gamma sterilizable sensors is needed in single-use bioprocess components. In this study, we explored pH sensing films based on polyaniline (PANI) that were deposited onto our recently developed passive radio-frequency identification (RFID) sensors.

RFID sensor networks with the Intel WISP
Proceedings of the 6th ACM conference on Embedded network sensor systems, 2008We demonstrate a simple RFID sensor network comprised of an Intel WISP and a commodity UHF RFID reader. WISPs are devices that gather their operating energy from RFID reader transmissions, in the manner of passive RFID tags, and further include sensors, e.g., accelerometers, and provide a very small-scale computing platform.

RFID Sensors in Medical Applications
IEEE Journal of Radio Frequency Identification, 2020Medical information systems are expected to be useful for both logistical and medical personnel. As such, the systems are reliant upon the sensors implemented to acquire information for both groups. Currently, such sensors may be divided by their competency in environment sensing or object identification.

UHF RFID sensors based on frequency modulation
2016 IEEE SENSORS, 2016This paper describes passive wireless light and pressure sensors. The sensed information is carried in the modulation frequency of the sensors and they could be made compatible with the existing UHF RFID standards. Light and pressure sensors are demonstrated at 867 MHz and they provide a read range of 12 m and 10 m respectively, assuming a typical UHF ...
