The device uses an ultrasonic sensor to detect nearby obstacles and provides real-time audio feedback, helping users navigate their environment more safely and independently.

"They are also inexpensive because we use readily available materials, and the power consumption is very low," says Ahmed. The researchers call their development SonoTextiles. They have transformed ...
