Question

A team of British scientists is developing “intelligent” clothes that will give disabled children

the power of “speech”. Children wearing waistcoats made of a unique electrotextile, linked to a

speech synthesiser, will be able to make themselves understood simply by tapping on the

touch-sensitive material.

The material is made up of normal cloth and an ingenious mesh of carbon- impregnated fibres

that can conduct electricity. When pressure is applied to the fabric, the pattern of signals that

passes through the conducting fibres is altered and a computer chip can work out where the

cloth has been touched. It then can trigger whatever electronic device is attached to it, which

could be no bigger than two boxes of matches.

“The smart bit is in how we weave the fabric and how we send signals through it – and we can

weave it into existing fabric designs so you cannot see it’s in there,” says one of the scientists.

Without being damaged, the material can be washed, wrapped around objects or crushed. The

scientist also claims it can be mass-produced cheaplyCan these claims made in the article be tested through scientific investigation in the laboratory?
