SonoTextiles incorporate acoustic sensors within glass fibers, featuring tiny transmitters and receivers that enhance effectiveness while keeping costs low.

By employing multiple glass fibers, each tuned to a different frequency, the technology reduces data overload and enables real-time data transmission to devices like computers and smartphones.

Led by Professor Daniel Ahmed, the research team aims to create lightweight, breathable, and cost-effective smart clothing that is easy to wash and made from readily available materials.

While lab results are promising, researchers acknowledge that the durability of glass fibers needs improvement before practical applications can be realized, with metal fibers being considered as a potential alternative.

This study marks a novel approach in smart textiles by combining glass fiber with varying frequency signals, as noted by first author Yingqiang Wang.

A groundbreaking study published on May 19, 2025, in 'Nature Electronics' details the development of 'SonoTextiles' by researchers at ETH Zurich.

These innovative smart textiles utilize acoustic waves traveling through glass fibers to measure vital metrics such as breathing and hand movements.

The system operates using ultrasonic frequencies around 100 kilohertz, which are inaudible to humans, allowing it to seamlessly integrate into daily life.

These textiles could also assist in monitoring posture, helping users correct poor alignment and preventing pressure ulcers, particularly in wheelchair users.

The innovation emphasizes efficiency, cost-effectiveness, and user comfort, suggesting broad adaptability and innovative applications in the future.

The potential applications of SonoTextiles are vast, including real-time monitoring for asthma patients, posture correction, and even enhancing athlete performance by preventing injuries.

The successful lab tests indicate that SonoTextiles could revolutionize patient care by enabling real-time monitoring and assistive technologies.
