Journal ArticleDOI
Wearable passive E-textile UHF RFID tag based on a slotted patch antenna with sewn ground and microchip interconnections
TL;DR: In this paper, a wearable passive UHF RFID tag based on a slotted patch antenna comprising only textile materials (e-textile, textile substrate, and conductive yearn) is presented.
Proceedings ArticleDOI
Analysis of wireless powering of mm-size neural recording tags in RFID-inspired wireless brain-machine interface systems
TL;DR: This paper characterizes wireless RF link between an external transmit antenna and an implantable antenna using the two-port model and presents the design of a novel 1-mm3 implantable loop antenna and four different external loop antennas with various features to analyze aspects and factors limiting the wireless power transfer.
Proceedings ArticleDOI

TL;DR: An approach to modeling and characterizing wireless channel properties for mm-size neural implants and effects of variability and uncertainty in human anatomy and dielectric properties of tissues on these radio links are explored.
Journal ArticleDOI
Wireless Measurement of RFID IC Impedance
TL;DR: A wireless method is proposed and demonstrated, based on electromagnetic simulation and threshold power measurement, applicable to fully assembled RFID tags, to determine the mounted IC's input impedance in the absorbing state, including any parasitics arising from the packaging and the antenna-IC connection.
Journal ArticleDOI
Inductively Powered Pressure Sensing System Integrating a Far-Field Data Transmitter for Monitoring of Intracranial Pressure
TL;DR: This work presents a battery-free pressure sensing system for minimally invasive ICP monitoring that comprises a cranially concealed wireless pressure sensor and on- and off-body external units and presents the electromagnetic modeling of the system.
