Intelligent Bras To Offer More Support

This business of intelligent design is baffling. I'm struggling with an unlikely article in the Journal of Biomechanics. This contains the information that scientists at the University of Wollongong, Australia, have designed a brassiere made from intelligent fabric with inbuilt sensors that will fit women more adequately. I'm sure half of you knew that a poorly designed bra is uncomfortable and may even injure you, the wearer that is, not the person alongside her. Apparently, even a bra in the correct size can dig into the skin at the straps and damage the nerves so seriously that the fingers go numb. This is particularly likely when vigorous movement takes place, which can cause the chest to move up and down 70 cm at a time. It comes about partly because the female breast contains no bones or muscles to support it. The rather puzzling bit is that in the experiment a woman aged 30 with a 36D brassiere and another aged 39 with a 38D walked at 4.3 miles (7 kilometres) an hour and jogged at 10 kilometres an hour. The vertical movement on the younger woman was 11 walking and 53mm jogging and on the older woman 25mm walkiing and 68mm jogging. Fascinating. So what? What the researchers are trying to do is use polymer science to enable sensors to be inserted into fabrics to monitor the motion of the breast and how the bra responds to it. Designers will in future be able to use fabric sensors work out how each part of the bra responds to movement.
I admit to scratching my pate about this. How does this help the person wearing the bra? I mean, 'Don't worry love, we know it's hurting. Here's why. We hope one day people won't build bras with buckles and straps. They'll be stick ons. I can promise that whatever sport you indulge in, they won't hold you up.'
