Carnegie Mellon Specialist on Sensor Systems Used on Pills Authentication Gives a Talk in Porto   

Carnegie Mellon University (CMU) Faculty Member L. Richard Carley, will deliver a talk about the Integrated Passive Single-Chip RFID/Sensor Systems. This new technology, with potential applications as the medicinal pill authentication and as in-vivo biological sensing, is his main area of research at CMU. The talk will take place at Faculdade de Engenharia of the University of Porto on October 6.

The medicinal pill authentication, for example, is especially important considering that lifesaving prescription drugs can cost $1,000 per pill, which makes them an extremely attractive target for counterfeiters. The solution developed by L. Richard Carley’s CMU team consists on a tiny RFID transponder with an encrypted identifier that can be embedded in each pill and that could help reduce the counterfeiting of these drugs.

The session will take place this Thursday, October 6, at 2:30pm in room I-105 (building I of FEUP, -1 floor).

 

“Toward the Design of Integrated Passive Single-Chip RFID/Sensor Systems”

Abstract:

The design of fully integrated RFID/Sensor Systems, ones in which the antenna, the RFID circuitry, and the sensor circuitry are all fabricated on the same integrated circuit substrate, is challenging because the small size of the antenna and its proximity to a resistive ground plane (the integrated circuit substrate) both decrease the RF energy that can be harvested to operate the passive system. This presentation will present simplifying approximations in order to develop basic equations demonstrating the challenge posed by the size and geometry of the antenna to the ability of the RFID system to harvest energy; and, these equations will be validated with electromagnetic field simulations. The presentation will also include results on a novel out-of-plane integrated antenna structure that offers a 1000X improvement in power transfer. Finally, the presentation will examine the challenging issue of matching the antenna to the on-chip electronics and efficiently converting it to a voltage that can power on-chip circuitry.  The presentation will end with a brief exploration of potential applications of this new technology to medicinal pill authentication and to in-vivo biological sensing applications.
