Fit to be worn

A Carleton electrical engineering professor has recently launched a sensory network device he says revolutionizes intelligent wearable fitness technology.

The “LEO” device leaves other activity trackers in the dust – the ones that use accelerometers to estimate the number of calories burned don’t do well at measuring the heart rate, hydration level and body fat percentage, for example.

LEO, a textile band interwoven with silver conductors that the user wears on the thigh while exercising, monitors muscles, heart rate, hydration levels and other anatomic activity. A Bluetooth Low Energy protocol then sends intuitive visualizations wirelessly to an app on the user’s mobile device in real-time, with straightforward, understandable recommendations, and communicates the data to a cloud server for further analysis. Users can share and compare their data with friends and competitors.

The device began in Leonard MacEachern’s imagination eight years ago when he was somewhat overweight. Passionate about technology and about fitness, MacEachern admits, “I was a pretty hefty guy. I started lifting weights and lost a lot of weight. But there was nothing to tell me my muscle activation level. A really serious athlete wants to know about lactic acid, fatigue levels, muscle sequencing and muscle co-ordination.”

Three years ago, MacEachern met Mark Klibanov, who has experience in biomedical device design. They and a few other students began to develop a device that could monitor muscle activity as their fourth-year engineering project. “MuscleMate,” worn like a blood-pressure cuff, used an electromyographic gesture recognition system to detect the tiny electrical signals generated by the wearer’s arm muscles. A microprocessor converted the biological analog signal into a digital one to read on a smartphone or computer. The novel gesture recognition software then detected the intensity and frequency of the impulses to determine strength and bodily actions.

Originally intended for use in video gaming, MuscleMate won local and regional awards and was the first to win the $40,000 Carleton University Capstone Award, which funded the team to begin commercializing the project.

Additional funding came through Carleton Entrepreneurs’ Lead to Win program and, last August, GestureLogic incorporated, with an entrepreneurial team that combines experience and expertise in business, sales, athletics, industrial design, machine intelligence, electrical engineering and biomedical engineering. All 11 are or were Carleton students, and MacEachern foresees a staff of 20 in the near future.
Klibanov, now 24 and GestureLogic’s product developer, is responsible for the original technology and finds the idea of being an innovator appealing.

“Many activity trackers are very primitive. We tore down that whole concept. We don’t want to track motion. We want to track your body’s bio signals.”

The science, he says, was already there.

“It just wasn’t in a wearable practical device. We packaged existing technology by pulling together different pieces of the puzzle.”
An innovation and collaboration facility on Carleton’s campus has facilitated meetings for GestureLogic and has contacted funding agencies on its behalf.

In mid-May, GestureLogic presented LEO at the Discovery innovation-to-commercialization conference hosted by the provincially funded Ontario Centres of Excellence, and is moving ahead with a campaign launch on Indiegogo, a platform to help entrepreneurs plug into the startup community.

“Our commercial project is aimed at the average person who wants to exercise,” says MacEachern, who explains the device not only can improve fitness and training efficiency, but also can reduce the risk of injury.

“It gives the user an unparalleled level of insight into what’s actually happening. Users will get the metrics they need to improve or excel in their preferred sport.”

In spite of the complexity of the technologies GestureLogic employs in the device, the company is making the technology accessible by keeping the price point at a reasonable level. The major target market is cyclists and runners, but the technology could apply to soccer players or, in fact, any sport.

“I like the idea of wearable technology to motivate people to get into shape,” says MacEachern. “If you have a way of quantifying what you are doing, to track your progress, and to not get hurt while you are doing it, then you will stick to it.”
This summer, says MacEachern, he plans to take up outdoor cycling and use his device to continue to improve his own health and fitness.

Barcoding life, one species ...

Sharon Oosthoek | May 2, 2016

Nobody knows for sure how many species exist. But scientists are certain we have identified only a fraction of the plants, animals and fungi on the planet — roughly 1.7 million species out of an estimated 10 to 20 million. "Most of the yet-to-be-identified species will be tinier life forms, but the numbers could even be larger," says University of Guelph biologist Paul Hebert. "That's just a best guess." Making an inventory of all life then would seem a Sisyphean task. But back in 2003, Hebert and his research team proposed a DNA tool for doing exactly that. At the same time, they made a convincing case for why we might want such an inventory: our species is accelerating the extinction rate of other species, and as Hebert puts it, "people take action when they know what is happening to life." Their argument was convincing enough to lead to the creation in 2010 of the International Barcode of Life (iBOL) project, an alliance representing 26 countries and headquartered at the University of Guelph.  Since then, affiliated researchers have collected from all over the world biological samples such as feathers, fur, blood and tiny bits of tissue. In 2015, they reached their goal inventorying half a million species. They have now set a ambitious target of identifying all species on the planet by 2040. As Hebert and his team originally envisioned, the tool the researchers are using to identify species is a short section of DNA from a standardized region of the genome, found in all living things. The sequence of the molecules that make up that chunk of DNA can be used to identify different species, in the same way a supermarket scanner uses the black stripes of the UPC barcode to identify purchases. As an added bonus, the DNA section is short enough to be sequenced quickly and cheaply, yet long enough to discriminate species. Fish out of water The tool has already been used to identify invasive species and the illegal sale of mislabelled endangered fish. While Hebert and his team are certainly on board with that, their ultimate vision has always been much loftier. "Each species is a book of life that describes how to reconstruct a robin or a blue jay or a monarch butterfly," says Hebert. "It's possible that by the end of the century, one-sixth of those books of life will not longer be with us. One of the objects of our work is to register all the species on the planet before they disappear." But this isn't just about creating an inventory. Rather it's about creating a digital Noah's ark. Along with the identifying section of DNA, the barcode project saves each species' entire genome — in other words, its complete set of DNA, representing instructions for building each species. That means the chemical pathways responsible for producing yet-to-be-discovered life-saving drugs will be preserved. "It's even possible that we might be able to reconstruct species," says Hebert. "Maybe humanity will decide it's sad living on a planet with few other species on it. It would be completely impossible to restore lost species if we don't have their DNA. "        

Creating community through cuisine

Emma Drake | April 27, 2016

Food is more than a meal; it can be intrinsic to a person’s identity. But for refugees, part of their identity is challenged when they settle in countries that don’t offer foods from home. “We share culture and richness through food,” says Valencia Gaspard, a PhD student in rural studies at the University of Guelph. “Food can be used to build communities and bring people together.” Valencia is part of a team of student studying the availability of ethnocultural foods in Toronto. They will be examining how these foods are used to manifest a culture through cuisine. “Keystone ingredients, such as camel’s milk or sesame oil have great importance to the meal,” she says. “Not being able to choose what you eat is dis-empowering.” read more »

Farmers get ahead of ...

Araina Bond | April 19, 2016

Anticipating Mother Nature has always been an important part of farming. Now farmers in Northeastern Ontario can make more informed decisions using real-time data about environmental conditions, thanks to Nipissing University researchers. The Nipissing team has created an online system called GeoVisage, which uses seven weather stations throughout Northern Ontario to collect data on microclimates. That includes air and soil temperature, relative humidity, wind speed, leaf wetness and photosynthetically active radiation — that is, sunlight plants can use for photosynthesis. read more »

Quinoa puts down roots ...

Jessica Shapiro | April 14, 2016

Ancient Incas considered quinoa their most sacred food. Packed with protein, vitamins and amino acids, it gave them stamina, strength and energy needed for survival. No wonder NASA has researched growing quinoa on long journeys to outer space. Despite the seed's explosion in world popularity over the past few years, including a massive increase in demand throughout North America, almost no farmers outside the Andes Mountains in South America grow it. Issues related to quality, supply, cost and importation have encouraged scientists to experiment with cultivating the crop in Ontario. At the Trent University Sustainable Agriculture Experimental Farm, Mehdi Sharifi is working with his students to make organic quinoa production viable for Ontario farmers. read more »

Fine tuning fungi’s ...

Sharon Oosthoek | April 8, 2016

Nobody takes revenge like Mother Nature. After all, she created entomopathogenic fungi — organisms that not only kill crop pests, but offer up nutrients in the insects' bodies to the plant. "It's a cool mechanism," says University of Brock PhD biotech student Larissa Barelli who studies evolution of these fungi. "Certain species can drill through the insect's cuticle, grow within it and eat it from the inside. They can also release toxins that kill the insect. The fungi then transfers nitrogen from the insect to the plant." read more »
