Smart suit doesn't miss a beat
by Geraldine Hinter
Imagine wearing a smart T-shirt or a suit embedded with tiny electronics that can monitor your heart or respiratory function wirelessly. When dirty, you take it off and throw it in the wash or have it dry-cleaned.
You can then place it on an electronic hanger that downloads the monitored data to a computer in your wardrobe and recharges the garment ready for wearing.
And there’s no need to worry about your heart skipping a beat while your garment is being cleaned – instead of having just one heart monitor, you can have a wardrobe of them.
That’s just one possible application of the garment integrated electronic technology being developed by researchers from UniSA’s Wearable Computer Laboratory.
Professor Bruce Thomas from the School of Computer and Information Science points out that his researchers were not the first to think of this technology, but "we’re the first worldwide to develop smart garment management technology that works," he said.
"The wardrobe has a touch screen on the outside and conductive metal bands spanning the hanging rail inside, with wires connecting it to a computer in the base of the wardrobe. When we place electronic hangers, each with their own ID and metal connection, on the rail, it detects the hangers and smart garments incorporating the conductive material and integrated electronics," Prof Thomas said.
"Through this connection, the computer identifies, for example, that hanger 123 has coat 45 on it, which has stored heart monitoring data that needs to be downloaded and the hanger recharged," he said.
Garments with communication technology only and a wireless connection enable users to access heart monitoring through a simple Bluetooth or ZigBee network, eliminating the need for expensive heart monitoring equipment to be placed in each garment.
Smart garments in the future may be used for a range of other monitoring services such as at home outpatient care and for people with dementia, enabling them to have a full life for as long as possible with a minimum level of intervention – and they can be monitored without having to learn to use a new device.
"The garments enable us to monitor people’s vital statistics and activity levels – when they get up, walk around, make breakfast and dinner, or sleep - but more importantly, we can determine if they are missing meals, fall over or stop moving. The technology can distinguish between normal and abnormal events and alert family or emergency services or, for people who live in retirement villages, alert local medical staff," Prof Thomas said.
The smart wardrobe can also be adapted for other uses including the self-diagnosis of faulty monitoring equipment; scheduling cleaning and dry-cleaning; a fashion butler to help people accessorise, colour match and select appropriate clothing for special occasions; and for preloading news, music and daily schedules into smart garments.
The research is being undertaken by computer and information science PhD student Aaron Toney and final year computer systems engineering student Wynand Marais, under the supervision of Prof Thomas.
