AI Article Synopsis

  • Traditional RFID readers use a complex design with multiple chips, which can lead to issues with cost, power consumption, and reliability.
  • This paper introduces a fully integrated RFID Reader System on Chip (SoC) that combines various functions onto a single chip, utilizing a Cortex-M0 core for improved efficiency.
  • The SoC is small (11.95 mm²), compatible with multiple RFID protocols, and offers improved performance and integration over existing designs.

Article Abstract

The traditional RFID reader module relies on a discrete original design. This design integrates a microcontroller, high-frequency RFID reader IC and other multiple chips onto a PCB board, leading to bottlenecks in cost, power consumption, stability and reliability. To align with the trend towards high integration, miniaturization and low power consumption in RFID reader, this paper introduces a fully integrated RFID Reader SoC. The SoC employs the open-source Cortex-M0 core to integrate the RF transceiver, analog circuits, baseband protocol processing, memory and interface circuits into one chip. It's compatible with ISO/IEC 14443 A-type and B-type and ISO/IEC 15693 transmission protocols and rates. Manufactured using a 0.18 μm process, the chip is compatible with multiple standards. The optimized design of the digital baseband control circuit results in a chip area of only 11.95 mm2 offering clear advantages in both area and integration compared to similar work.

Article Synopsis
  • Black-bellied Whistling-Ducks (BBWD) are moving north into areas occupied by Eastern Wood Ducks (WODU), but their nesting habits are still not well understood.
  • To研究 their nesting behavior, researchers utilized advanced technology like passive integrated transponder (PIT) tags and RFID readers on nest boxes, allowing them to track visits and behaviors of both BBWD and WODU during key nesting stages.
  • The study found that while both species visited new and old nest boxes equally, BBWD favored old boxes for nesting significantly more than WODU, challenging previous expectations and highlighting gaps in traditional research methods.

Multilevel Printed Wearable Radio-Frequency Intelligent Identification Platform for Object Recognition.

ACS Appl Mater Interfaces

September 2024

State Key Laboratory of Millimeter Waves School of Information Science and Engineering, Southeast University, Nanjing 210096, China.

As a noncontact target recognition technique, radio-frequency identification (RFID) technology demonstrates attractive potential in constructing human-machine interaction (HMI) systems. However, the current development of RFID technologies in HMI systems is hampered by critical challenges in manufacturing high-performance RFID readers with superior flexibility and wearing comfort. Hence, we propose a multilevel printing strategy to overcome the difficulties in manufacturing high-performance large-scale microwave systems.

Quality has been a concern of the World Health Organization since its inception and is defined as fitness for use. Since our ancestors began trading several millennia ago, Falsified Pharmaceutical Products has been a recurring problem and still threatens economic stability and public health. Its definition various from country to country and according to World Health Organization, 2017, it is 'a product that is deliberately and fraudulently mislabelled with respect to identity and/or source'.
