A new shirt could help music bands rock the house--without instruments!
The long-sleeved T-shirt is able to detect the movement of your arms as you strum an imaginary guitar. The shirt's creator. Richard Helmer. an engineer at CSIRO Textiles and Fibre Technology in Australia, imbedded sensors in the elbows of the shirtsleeves, Each time your elbow bends, a sensor sends an electrical signal wirelessly to a computer.
