His smart bracelet serves as a guide for the blind

Almost 40 million people worldwide suffer from blindness according to the WHO, of which almost 1.5 million are under the age of 15. Learning to operate in a world full of “invisible” obstacles poses a major challenge for these people and their families.

To alleviate these challenges, the young innovator Marco Trujillo has developed SUNU, a wearable device that works similarly to parking sensors, but using vibrations instead of sound. For 349 dollars (approximately 320 euros) the Ustraap bracelet has the potential to transform the lives of millions of blind people by providing the user with useful information about the objects around them, helping them to get around without trips and falls.

The bracelet has battery life of eight hours of active usage (the device is only activated when the user is in motion), which translates to a full week of normal use.  Recharging the device is as simple as placing it atop a wireless charger provided with the bracelet.

The commercial version of this product will also include a user guide and a SunuTAG, a smart tag that interacts with the bracelet, allowing the user to locate the item to which it is attached. In this way, the quintessential search for keys, purses, or “finding the door of your hotel room” become things of the past, Trujillo points out.
