Wearable Technology - New Apparel Measurements

My T-Shirt Told Me to Take a Chill Pill

OMsignal makes shirts with sensors that track vital signs, calories burned and even stress levels.
My heart rate, for instance: 62 beats a minute. And my breathing: 17 breaths a minute.My T-shirt tells me things.
Unless I drink too many cappuccinos or a deadline looms. Then my T-shirt tells me my that heart rate has jumped to the high 80s, my breathing to 22.
My T-shirt is connected to me and also to the Internet. So along with an iPhone app, it can remind me to take a breath, relax, chill.
Seriously. The T-shirt I’m wearing was made by OMsignal of Montreal. It has sensors that are supposed to pick up all sorts of data about me — the aforementioned vital signs, plus how many calories I burn and even how stressed I am.
OMsignal is a part of a new breed of young companies focusing on wearable technology. We’re not talking about Google Glass here. These are products made out of biometric materials, or smart textiles. And yes, these products are starting to hit the market. Their fans say they could represent the future of wearable computing.

Lots of people wear fitness bands that can monitor their health. Whether those products deliver all they promise is questionable. But why wear a wristband when you’re already wearing clothes? Weave some sensors into the fabric, and you have one accessory fewer to worry about.
“Smart clothing is easy because it’s the only wearable medium you’ve already been wearing your whole life,” said St├ęphane Marceau, co-founder of OMsignal. “In a decade, every piece of apparel you buy will have some sort of biofeedback sensors built in it.”
Many challenges must be overcome first, not the least of which is price. OMsignal shirts start at $80, but they also need a module, which powers the shirt and talks to its sensors, that costs $120. But the shirt is machine washable.
“The leap that you have to make from a prototype or small-lot sizes of these wearables to an affordable mass-market product is pretty significant,” said Jonathan Gaw, research manager for IDC Research. “The price is going to have to come way down before it becomes a product for most consumers.”
The OMSignal shirt connects with a smartphone app to provide readouts of the data collected about the person wearing the shirt.OMSignalThe OMSignal shirt connects with a smartphone app to provide readouts of the data collected about the person wearing the shirt.
Mr. Gaw said that wearable apparel would be used first for fitness, wellness and medical applications by a select group of consumers. He warned that it could be slow going for most people. “In terms of these being mainstream, and something that people will use on a daily basis, you’re getting into Buck Rogers territory there,” he said.
But Mr. Marceau of OMsignal said consumers were getting to a point where they want more information about themselves. “The first cars were completely blind. Then you had a gas gauge. Then a speedometer. Now you can’t imagine a car without these things,” he said. “Smart clothing is starting to do the same thing for the human body.”
Most smart textile products use conductive yarns that can transmit electrical signals. The sensors woven into these materials are either so small you can’t see them or so flexible you don’t notice them. While many of these garments require a battery pack of sorts, some are experimenting with applications in which a smartphone can transmit power and Internet access to sensors and screens that are attached to the clothing.
“This type of fabric, until now, was a laboratory experiment, and no companies were able to develop something that would be a mass-scale product,” said Eliane Fiolet, co-founder of Ubergizmo, the technology website. “Now you have companies that are claiming to figure out a manufacturing process that is viable to introduce these garments at scale.” Ms. Fiolet said incorporating sensors into clothing, rather than wristbands, made sense. Clothing, after all, covers more of the body.
These sorts of devices are already emerging out of labs. Cityzen Sciences, based in Lyon, France, makes T-shirts that have microsensors embedded in the fabric. These sensors can monitor a person’s temperature, heart rate and location. The company won the award for the most innovative new product at this year’s International CES.
Sensilk, based in San Francisco, is making a smart bra with sensors to track a wearer’s fitness. And the Defense Advanced Research Projects Agency has funded a number of projects to make wearable computerized clothing for soldiers. Researchers at theMassachusetts Institute of Technology have developed a product called WearArm, which is a computing platform like iOS or Android, but one specifically for smart clothing.
The possibilities don’t end there. A number of universities and research labs have experimented with wearable technology that can help blind people navigate city streets, such as gloves that vibrate when a user needs to make a turn. And then there is Studio Roosegaarde, a design lab in the Netherlands. It has developed a dress called Intimacy 2.0 with an opaque fabric that becomes transparent when its wearer is aroused — bringing T.M.I. to a whole new level.

Discounts, Discovery & Delight: 3Ds for Retail Success

In fashion and retail, Dopamine is the drug of choice. Technically, Dopamine is the neurotransmitter of “desire.” Dopamine leaps across synapses in our brain to control our reward and pleasure centers. It enables craving. It induces repeat behaviors. It makes us want more. Therefore, it is in our best interest to create products and experiences which induce the release of dopamine in our consumers. We could use some dopamine for ourselves, too. In our fashion and retail world, there are three primary stimuli, "3Ds," we can control to deliver hits of dopamine: Discounts, Discovery and Delight.
