Imagine wearing a T-shirt that measures your breathing or gloves that translate your hand movements into commands for your computer. Researchers at ETH Zurich, led by Daniel Ahmed, Professor of Acoustic Robotics for Life Sciences and Healthcare, have laid the foundations for just such smart textiles. Unlike many previous developments in this area, which usually use electronics, the ETH researchers rely on acoustic waves passed through glass fibres. This makes the measurements more precise and the textiles lighter, more breathable and easier to wash. “They are also inexpensive because we use readily available materials, and the power consumption is very low,” says Ahmed.
