Researchers at ETH Zurich have developed SonoTextiles, smart fabrics that use sound to measure touch, pressure, movement, and more.
The fabric integrates thin glass fibers acting as acoustic sensors, allowing detection and interpretation of changes in sound waves when the fabric bends, stretches, or moves.
SonoTextiles are more precise, cheaper, energy-efficient, and comfortable compared to traditional smart textiles and have potential applications in healthcare, sports, accessibility, and posture improvement.
Challenges remain in making the technology more durable and practical for everyday use, such as exploring the use of more durable materials like metal and improving the integration of electronics into the fabric.
