Smart and Intelligent fabric allow designers of sport bras to improve the comfort for active women according to a demonstration of an Australian research team from the University of Wollongong.
Fitted with tiny sensors, the smart-bra fabric will monitor and measure movement of the breast.
Two volunteers, aged 30 and 39, one wearing a 36D bra and the other a 38DD, were instructed to walk on a treadmill at 4.3mph and then speed up to a jog of 6.2mph.
The finding of this test: all the strain and stress from the breast movement, which can be as much as 2.7 inches during jogging, is being borne by the straps. This could explain the shoulder pain and tingling in the arms that many women suffer during physical activities. Done over prolonged time, these ill fitting bras could cause long-term nerve damage.
According to the UK’s Telegraph, as many as 80 percent of women are estimated to be wearing the wrong bra, particularly during exercise and thus increasing the risk of pain and nerve damage caused by bra straps.
This analysis was the first time textile sensors for breast movement were used as oppessed to rigid parts that have been incorporated into bras, to test the level of movement in the past.
Thanks to the development of intelligent fabrics, brassiere designers have now the ability to directly assess the effects on wearing comfort of each brassiere component.
