Smart(er) Healthcare: Designing RFID Tags for Biomedical Applications

Brianne Costa April 19, 2018

When it comes to advancements in healthcare, we have a lot to be thankful for. Because of anesthesia, patients no longer need to “bite the bullet” during surgery. Thanks to antibiotics, doctors don’t use bloodletting to cure an infection. Moving into more modern times, radio-frequency identification (RFID) systems offer a wide variety of innovative healthcare applications. However, like any new medical technology, biomedical RFID devices must be rigorously evaluated for performance and compatibility with other medical systems.

In early 2018, the northeast coast of the U.S. was hit with three major winter storms (locals “lovingly” call them nor’easters) all in a matter of weeks. Cape Cod in Massachusetts faced especially severe coastal erosion that damaged many homes and businesses. After one of the storms, residents surveyed the aftermath and noticed something interesting…

Pablo Rolandi from Amgen delivered a keynote presentation at the COMSOL Conference 2017 Boston. The topic? How Amgen is moving beyond modeling and simulation for biopharma development. Rolandi shared five examples that illustrate this idea across both biologic and synthetic medicine applications. If you missed his presentation, you can watch a recording of the video and read the highlights of what he discussed here.

“Where?” “Of what?” “Why?” These are questions often asked of someone who is planning on getting a tattoo. Another common question: “Is it safe?” You can vet the cleanliness of a tattoo parlor and the artist’s qualifications, but there hasn’t been much research into what happens to ink once it enters the body. A research group recently investigated if tattoo pigment can harm skin and the lymphatic system using techniques such as mass spectrometry and X-ray fluorescence.

Want a roadmap to modeling cables? We have a six-part tutorial series for you. The Cable Tutorial Series shows how to model an industrial-scale cable in the COMSOL Multiphysics® software and add-on AC/DC Module, and also serves as an introduction to modeling electromagnetic phenomena in general. The numerical model is based on standard cable designs and validated by reported figures. Keep reading for a sneak peek of what you’ll learn when you roll up your sleeves and start the series.

Magnetic flow meters are a noninvasive option for measuring blood flow. However, when patients move, displaced blood vessels can affect the sensitivity of the flow meter. Researchers from ABB Corporate Research used multiphysics modeling to study how the displacement of blood vessels in a moving patient impacts the performance of a magnetic flow meter.

There is a lot we know about the brain, and a lot we don’t. Optogenetics is a relatively new area of study in which light is used to stimulate brain activity and study neurological behavior. Stimulating neurons with light is more precise than electrical stimulation — and safer. Researchers from Massachusetts Institute of Technology (MIT) used simulation to design an optical probe that can be implanted into the brain to stimulate nerve impulses.

My favorite novel to read around the Halloween season is Stephen King’s It. A common misconception about the book is that “It” is just a scary clown — It is actually the embodiment of whatever you fear most. If what scares you the most is the possibility of ghosts, don’t worry: a researcher used acoustics analysis to explain that whatever scares you this Halloween, like It, is just a trick of the mind (and vibroacoustic effects…)

Imagine that reading books with no pictures and 12-point font is all you know. One day, someone hands you a pair of 3D glasses and takes you to see a movie. This is how thousands of researchers and scientists in astrophysics might feel right now — they have been closely working on the recent groundbreaking gravitational waves discovery that enables us to get a clearer, brighter view of the universe.

“I think I can safely say that nobody understands quantum mechanics.” — Richard Feynman, in The Character of Physical Law (1965). Although the Nobel-prize-winning physicist might have been speaking in jest, quantum mechanics is a difficult concept to teach — and simulate. Modeling a double-barrier structure in the COMSOL Multiphysics® software can help teach quantum mechanics concepts to physics students as well as enhance the research and development of semiconductor devices.

A leading cause of smog and particulate pollution is the harmful emissions from automobiles, especially those that run on diesel engines. Today, most vehicles with diesel engines are required to install a diesel particulate filter (DPF) to catch carbon-based particulates that are emitted from their exhaust. Using the COMSOL Multiphysics® software, we can analyze the acoustics of a DPF.
