Nearly 66% of Americans say they can manage their finances without credit cards, 60.3% use them weekly. This dependency can lead to significant financial burdens if balances are not paid in full ...

Nanomedicine involves the use of nanoscale materials, such as biocompatible nanoparticles and nanorobots, for diagnosis, delivery, sensing or actuation purposes in a living organism.

This repository contains an ESP-IDF board support package for Arduino Nano ESP32 board. This board is based on an ESP32-S3 chip. This component includes the blink example. It can be used as a starting ...

In this paper we study the problem of tag identification in multi-reader RFID systems. In particular, we propose a novel solution to the reader-to-reader collisions and tag collisions in multi-reader ...

This describes how to build low-cost RFID Wands for to read and write UHF RFID tags. Using these with (for example) and Impinj R420 reader, you can read and write UHF RFID tags from four stations at ...

AC-DC rectifier and storage capacitors take up 25% or more of chip area for cost-sensitive passive RFID tags. In this work, we show that these components can be eliminated by utilizing a RF-only ...
