Radio-frequency identification RFID involves the wireless use of radio-frequency electromagnetic fields to transfer information and identify and track objects with the use of an RFID transponder, or tag, attached to the object in question.

These tags are now frequently seen in everyday products, produce, payment cards, and even livestock.

A reader is used to interrogate the tag through electromagnetic fields as illustrated in figure i below and information is transmitted back from the tag. With their ever increase in use, there is a rising need to reduce their energy requirements and the size of the tags, while maintaining or maximizing the read range, i. RFID tags essentially consist of an antenna and a chip that have complex input impedances as illustrated in figure ii above.

Here, R c and R a are chip and antenna resistance, respectively. Z c and Z a are chip and antenna impedance, respectively. Additionally, by making use of the Friis free-space equation, we can also obtain an equation for read range, r :. In addition, we can input the reader system details such as power transmitted, P r ; the reader antenna gain, G r ; and operating frequency. The figure below illustrates the basic features of the RFID tag model, including air domain, perfectly matched layer PML regions, tag substrate, and antenna and chip geometries.

RFID Tag Read Range and Antenna Optimization

In order to have confidence in the analysis results from any numerical model, it is important to validate the model. This can be a very costly and time-consuming exercise.

It should be noted that Rao et al. In addition, the geometric and material details of the antenna and tag design were extracted from available images and text. We set up and ran a frequency sweep of the equivalent tag. Then, we compared the results of the read range and power transmission coefficient with the physical test data provided by Rao et al.

Comparisons of i read range and ii power transmission coefficient obtained from model vs. As you can see in the figure above, the model trends observed follow those of the physical data, but the COMSOL Multiphysics model peaks are found to be at slightly higher frequencies than those presented by Rao et al.

As expected, there will be a slight difference between the numerical and physical test data due to the limited chip impedance and material data provided in the literature. Moreover, small errors in the extraction of the antenna geometric dimensions may have occurred. We did, however, consider the small percentage deviations from the physical test data acceptable under these circumstances. We also deemed the modeling method able to correctly predict the observed read range.

Example tag antenna design When running this model, we obtained 0. The read range was deemed a little low compared to the required 2 meters for the application at hand. The geometric variables involved in the antenna optimization process included 34 length and width parameters as illustrated below.

We looked at two gradient-free optimization methods in the work; namely, the bound optimization by quadratic approximation BOBYQA method and the Monte Carlo method.Hey guys! Radio Frequency Identification is a technology that allows almost any object to be wirelessly identified using data transmitted through radio waves.

This technology allows you to identify and track individual items, as well as multiple items simultaneously, without a direct line of sight. If it is a mobile handheld like we will be using today, only a handheld reader and an RFID tag will be needed. I have set up my reader by downloading the app from the app store, and logging in.

Software can be bought or created that has additional functionalities to help an application. One example is with this reader and its app available for download on the App Storewe can assign a name and picture to a tag making it easy for us to find the tag we are looking for on-screen. Using this app, image, and name association with an individual tag allows you to locate the exact tag you are looking for, without searching through multiple EPCs.

And as always, if you have any questions at all, send us an email or give us a call. Here are a few quick facts about RFID.

Emerging electronic sample labeling technologies such as radio frequency identification RFIDas well as more traditional solutions, are described here. Using RFID to tag samples can reduce costs and errors in biobanking, providing important long-term benefits.

The example below illustrates the problem that will be addressed in this article. These excerpts, from the first few paragraphs of an article in The New York Times Magazine1 describe a researcher searching for a specific sample at the Fox Chase Cancer Center in Philadelphia:. Around each vial, on a thin piece of tape, someone had scribbled information about each sample.

She dropped it and grabbed the next one. Suddenly, she twirled to face me, arm extended, holding one tiny vial, grinning. But, there is a bigger problem here—the samples in the box are warming up and they are degrading.

If this search takes too long or is repeated enough, all the samples might be rendered useless. Separate from the issue of sample integrity, losing track of samples can wreak havoc both to the prestige and the financial standing of a biobank, as was illustrated by the discovery of untracked sample vials at the U.

It is not too hard to imagine situations in which losing or switching samples can cost lives. To add samples to a biobank, three things need to happen without fail. The first step will not be addressed here, except to say that standards for sample preparation are as diverse as the sample types themselves. The second step is creating an accurate database entry that includes all of the supporting information for that sample. The last step in accessioning a sample is perhaps less obvious—a robust connection between the physical sample and the database entry needs to be created.

How does one make this connection and what are the consequences of the different solution to this problem? In the not-too-distant past, sample databases were, at best, an organized laboratory notebook. These gradually moved to spreadsheets that had one important advantage—the database could be searched. For a small university lab with a small sample collection, a spreadsheet might still suffice.

Spreadsheets, however, have significant flaws for this type of application. For example, when using a spreadsheet, how does one deal with many millions of samples, several tiers of authorizations needed to access sample data, accurately document shipments, log sample handling, labeling? The list goes on. LIMS programs are typically more comprehensive and provide record management for experiments, track reagent use, laboratory supplies, inventory, and so on.

It may be tempting to believe that RFID functions thanks to the reader module containing a very small hamster with x-ray eyes, but in actuality, the system is a bit simpler than that.

Tags are embedded in small items like cards, buttonsor tiny capsules. There are two types of RFID systems: passive or active. The tag power system defines which type of system it is. In a passive RFID system, the tags do not use a battery; instead, they receive their energy to run from the reader.

The reader emits an energy field of a few feet, providing the energy for any tag in the vicinity. Passive tags have the benefit of being able to be read at a fast rate 10 or more times a second.

In general, the smaller the tag the much shorter the read range. Active RFID systems include tags that have their own internal power supply for increased range. Active tags possess a battery and usually have larger SMD components.

After a preset amount of time the tag emits an RF ' chirp '. A reader in the vicinity can listen and hear for this chirp. Because an active tag is they can be read over much larger distances than passive tags tens of feet. Downsides to active tags include greater bulk because of the batterylimited life span tag is dead when the battery is exhaustedincreased cost per tag, and varying report rates.

As well as active and passive systems, RFID systems can also be broken out into different frequencies. Some frequencies and systems are designed to only read one tag at a time, while others can read multiple.

Cost of readers can also vary wildly based the frequency rating of the modules. In prior years a reader capable of reading multiple tags was in the thousands of dollars, sometimes tens of thousands.We also briefly touched upon the way it might help researchers in the lab. Here we will go more in depth over the many uses for this novel technology in the research environment. Security is of paramount importance for laboratories.

In addition to having to safeguard valuable information, labs also often contain hazardous materials and high-value equipment that must be kept safe.

As such, access to the lab must be controlled, and even once in the lab practices must be in place to protect sensitive information and valuable materials. These innovative labels can be applied to high-value equipment as well as important samples and material. Tagging valuable equipment with RFID labels allows you to keep track of them and will let you know if they are removed from the lab. As opposed to readable text and even barcodes that can be scanned by anyone with a hand-held scanner, RFID labels can be encrypted to shield the encoded data, ensuring that sensitive information is kept confidential.

Asset tracking, or asset management, refers to the tracking of the location, status, maintenance schedule and other important information regarding physical assets.

The goal of any laboratory asset tracking system is to ensure asset control efficiency and to minimize loss. This is also of critical importance in the research environment, where hard to replace specimen must be carefully tracked and high-value equipment must be maintained in working order.

This usually involves removing each box, one at a time, and checking each individual sample found inside. This can not only cause the samples you check to potentially thaw, compromising their integrity, but it can also increase the temperature of the freezer itself, risking the preservation of all your precious samples. Moreover, identifying lab assets and equipment allows for scheduling of necessary maintenance and service, as well as preventative maintenance, and helps keep track of assets that may have come to the end of their lifecycle, and need to be replaced.

In addition, RFID label technology also has applications in the animal environments commonly used by research centers. RFID tags can be placed on the cages used to house animals. These tags can encode the protocol number, animal IDs, treatments done, and drugs administered. These tags also allow automated tracking of the cages in and out of holding rooms.

A well-managed supply chain with integrated inventory control is an essential component of proper lab management, and ensures results, accuracy and patient safety are not compromised. In addition, the ability to encode information onto the RFID chip, provides the means to keep track of the quantity used, the supplier and the expiry date. Linking this data to an automated database will ensure you know exactly what you have in stock, while also simplifying the ordering process, and ensuring supplier information is readily accessible.

This can lead to wasted time, supplies and resources, as well as expensive overnight shipping costs. Additionally, with multiple users in the lab, improper inventory control can also result in over ordering certain reagents, piling up unnecessary costs and increasing lab waste. Moreover, the benefits of RFID labeling become even more apparent when undertaking and conducting full inventory stock counts. While for the most part this exercise continues to be performed manually with the more advanced environments using barcode systems.

Nonetheless, both approaches are extremely time-consuming, typically taking several days to complete a full inventory audit. To this end, many laboratory managers are clamoring for a solution that would automate the inventory process and enable them to spend more time conducting experiments. The implementation of an RFID labeling system provides a much-anticipated solution to alleviate this situation.

With RFID readers placed at key points throughout the lab, all inventory, such as reagents, are constantly being tracked, which allows for real-time inventory accounting, ensuring accurate levels.

To this end, it becomes clear that the use of RFID labels provides several advantages not offered by traditional labels, or by barcoding, and that RFID labeling introduces efficiencies of scale benefits:.

However, RFID has several benefits over schemes that use barcode tracking software. Most remarkable is that the RFID tag data could be read outside of the field of view, while the barcodes should be connected with an optical scanner.

That's why I'm here. I didn't say it, but here's what I was thinking: "Wait a minute. These companies are paying your firm thousands of dollars a year to keep them up to date about the technologies they need to implement, and they have to tell you to go research RFID?

Shouldn't you already be on top of this and be advising them? Not much has changed in 20 years. Technology consulting firms still seem to be clueless about RFID. I read reports about the critical technologies for companies to adopt each year, and RFID is never on the list.

I see reports on what companies in industries must do, and they say things like "improve inventory visibility" and "get inventory accuracy rates up. It makes me want to become a consultant. I could do well consulting for sports teams. I don't want to paint everyone with the same brush. There are some great consultants out there, but the fact is that many tell customers what they want to hear. If they know a retailer has a dim view of RFID technology, they won't educate that company about why their view is misguided or out of date.

Why risk losing the customer?

Another issue, I believe, is that consultants don't want to go out on a limb and potentially risk earning a reputation of being wrong—or, worse, being fired. Just as CEOs are reluctant to be the first in their industry to adopt a new technology, consultants do not want to be the first to issue a report declaring a specific technology is critical to their customers.

It's safer to promote what others are already promoting. Eventually, RFID will reach a tipping point and all consultants will recommend it to their customers. Until then, it will be up to executives to educate themselves and learn how the technology can cut costs and dramatically improve efficiencies. Search for:. Subscribe Login Search.
