  • Sunu band may be the way that we navigate like bats navigate in the night.

    Dave Power, President Perkins School for the Blind.
  • Before using SUNU, I was skeptical. I have tried other similar devices in the past without much benefit. After using it, I was pleasantly surprised. I was able to avoid overhead objects quite easily and was also able to find doorways very easily.

    Thomas Cumings, Adaptive Technology Trainer

How does Sunu Band work?

The smart-bracelet uses a sonar transducer emitting an untrasound wave at a frequency that humans and pets cannot hear. The ultrasonic wave bounces off objects that are within the sensor's direction, and the resulting 'echo' is detected by the sensor. The resulting 'echo' is then be processed and converted into vibrations. The intensify of the vibrations depend on the bracelet's proximity to the object. The vibrations intensify as the user gets closer to an object or obstacle.
