Dr. Jukka Voutilainen

CEO – Voyantic

Speaks at ID WORLD on Wireless Identification

Dr. Voutilainen has been working with RFID technology from the beginning of 2001 when he started his master’s thesis about an RFID based moisture measurement system. He received his doctoral degree from Helsinki University of Technology in 2005, at the age of 25, and has since been a regular visiting lecturer in a number of universities, and has peer reviewed numerous conference and journal papers. He is also an inventor in three filed patents concerning RFID measurements.

In 2004, Dr. Voutilainen co-founded Voyantic Ltd., a Finland-based company that specializes in RFID measurement solutions. Voyantic’s Tagformance UHF RFID measurement system is currently used by more than 100 tag manufacturers, application developers, RFID end users, and universities in 20 countries around the world. Dr. Voutilainen started as the CTO of the company and led the development team for the measurement system. In 2009, he took over as CEO, and is now mostly focusing in new business development.

“TAG PERFORMANCE MEASUREMENTS IN THE UHF RFID INDUSTRY”

As UHF RFID technology has matured during the last years, the performance and quality of RFID tags is playing an important role. Tag performance measurements have been used for several years by tag manufacturers to verify their tag designs and the quality of the manufactured tags. Buyers of tags, i.e. application developers and end users, are also becoming more quality oriented as tag prices have gone down and many suppliers are promoting seemingly similar products.

When leading RFID tag manufacturers design new tags, they typically measure the sensitivity and backscatter signal strength of the tags as a function of frequency and orientation angle. That way they can verify that the tags are tuned correctly even when they are attached to different materials, and they can help their customers to use the tags most efficiently.

Manufacturing RFID tags has the quality requirements of the electronics industry, but the cost requirements of the process industry. The same performance measurements principles can be used there as well; however there is much less time to test a single tag. The typical approach is to perform a go/no go test with an RFID reader using constant frequency and power. However, more information about the process and the developed tags can be acquired by a more thorough characterization.

There are a lot of different tags available for RFID application developers and end users. Typically they have to make choices based on their experience and the datasheets provided by their suppliers. However, more and more companies are testing different tags themselves for the suitability in their own application. The selection is typically a compromise between tag size, performance, quality, versatility, and cost.
