Abstract
To enable remote, battery-free, and wearable health-care, ultra-low-power and highly-efficient energy harvesting and communication front-ends are required. This paper presents the design and implementation of a wearable backscattering modulator and RF energy harvester for UHF RFID applications, which represents the first textile-based RFID modulator. The measured performance of the modulator is characterized using s-parameters and is shown successfully communicating with a commercial RFID reader using a textile antenna, suitable for integration in a fabric bandage. The rectifier's efficiency is also presented, in presence of the modulator, showing a high RF to DC efficiency exceeding 50%. This work lays the foundation for UHF RFID-powered smart bandages for next generation healthcare applications.
