New ‘Ear Shirt’ Turns Audible Sounds Into Electric Signals

In the same way that our ears turn noise into mechanical motion and electromagnetic information, researchers have developed a cloth that acts as a microphone.

Nanometer-scale oscillations in all textiles are caused by audible noises, but these tremors are too tiny to be detected by the human ear on a regular basis. The scientists developed a bendable fiber that, once knitted into a cloth, folds with the textile-like kelp on the top of the ocean in order to catch these invisible impulses.

Piezoelectric fibers are intended to create an electromagnetic output when bent or physically distorted, allowing the mesh to transform sound waves into electrical impulses.

It was the team’s goal to design a smooth, resilient, comfy “ear” that could sense vibration and is influenced by the human hearing apparatus. Two significant findings came out of their investigation: A firm fabric is required to properly transform acoustic signals into vibrations in this cloth. In addition, the group would have to develop a thread that can also flex with the cloth while also generating an electrical output.

The material, once knitted inside the lining of a garment, may detect the delicate aspects of a wearer’s pulse. Some other fabric may sense sound generated by the threads, for example, recordings of spoken language.

For example, you could speak via an auditory clothing in order to handle phone calls or connect with other people. Through this fabric, users are capable of monitoring their cardiac and breathing conditions in real-time, comfortably, and without any discomfort.

Spacecraft skin may be fitted with it to monitor amassing dust, and structures can be fitted with it to identify fractures and stresses. The intelligent netting may also be used to keep track of fish in the water. A vast range of possibilities is being unleashed by the fiber.

The research was published in Nature.
