Screen Printed Chipless RFID Tags on Packaging Substrates


Abstract: "A chipless radio frequency identification (RFID) tag is a suitable low-cost alternative to any chip-based RFID one. The flexibility to use low-cost printing techniques makes chipless RFID a competitive technology. In this paper, we report an evaluation of the microwave performance of two different screen-printed chipless tags in the 3–6 GHz range. The tags were designed and scre... » read more

Securing Short-Range Communications


Short-range wireless communication technology is in widespread use and growing rapidly, adding conveniences for consumers while also opening the door to a whole range of cyberattacks. This technology is common across a variety of applications, from wireless key fobs to unlock a car and start the ignition, to tags used to help drivers find misplaced items such as car keys. RFID also is starti... » read more

Power/Performance Bits: July 20


Shrinking RFID chips Researchers at North Carolina State University built a new, tiny RFID chip. They expect the chip to help drive down costs for RFID tags, making it possible to embed them in more things for supply chain security. "As far as we can tell, it's the world's smallest Gen2-compatible RFID chip," said Paul Franzon, Professor of Electrical and Computer Engineering at NC State. I... » read more

Building Billions Of Batteryless Devices


Later this month, Arm will celebrate its 30 year anniversary and the engineering milestones that have resulted in more than 180 billion Arm-based chips being shipped in everything from sensors to smartphones to the world’s fastest supercomputer. In each of these cases, much of Arm’s success has been in our dedication to delivering the highest performance per watt. But while Arm may ha... » read more

System Bits: Aug. 20


Blockchain integrated into energy systems Researchers at Canada’s University of Waterloo integrated blockchain technology into energy systems, a development that may expand charging infrastructure for electric vehicles. In a study that outlines the new blockchain-oriented charging system, the researchers found that there is a lack of trust among charging service providers, property owners... » read more

MRAM: from STT to SOT, for security and memory


Abstract: "Spin Transfer Torque Magnetic Random Access Memory (STT-MRAM) is one of the leading candidates for embedded memory convergence in advanced technology nodes. It is particularly adapted to low-power applications, requiring a decent level of performance. However, it also have interests for secured applications. The PRESENT cipher is a lightweight cryptographic algorithm targeting ultra... » read more

Power/Performance Bits: April 23


Tiny spectrometer Engineers at the University of Wisconsin-Madison, Sandia National Laboratories, and Huazhong University of Science and Technology developed a miniature spectrometer small enough to integrate with the camera on a typical cellphone without sacrificing accuracy. This miniature sensor is CMOS compatible. "This is a compact, single-shot spectrometer that offers high resolution ... » read more

Artificial synapse for “brain-on-a-chip” portable AI devices In the emerging field of neuromorphic computing, researchers are attempting to design computer chips that work like the human brain, which, instead of carrying out computations based on binary, on/off signaling like digital chips do today, the elements of a brain-on-a-chip would work in an analog fashion, exchanging a gradient of... » read more

IoT Has Always Been With Us


By most accounts, Kevin Ashton of the Auto-ID Center at the Massachusetts Institute of Technology coined the term “the Internet of Things” in 1999, referring to a system of ubiquitous sensors connecting the Internet with the physical world. We were well into the 21st century before the Internet of Things, as a marketing term or a short description of a certain technology, came to be wide... » read more

System Bits: May 10


Topological insulators In a finding that could open up a new pathway to advanced electronic devices and even robust quantum computer architecture, researchers from MIT; Oak Ridge, and Argonne National Laboratories; the Institute for Theoretical Physics in Bochum, Germany; the Institute for Theoretical Solid State Physics in Dresden; the Ecole Normale Superieure in Paris; and the Institute of N... » read more
