Bracelets for vision impairment and night blindness
Dr. Soroor Behbahani, Assistant Professor of Biomedical Engineering and a member of the faculty of Islamic Azad University, Science and Research Branch, regarding smart bracelets for the visually impaired people, said: "We have been collaborating with Shahid Beheshti University to diagnose various retinal diseases and faced the challenges of various visually impaired and night-blind patients, therefore, we tried to come up with a solution to the problems of these people.
Referring to one of the problems of these people, she said: "Person with Nyctalopia experience blindness which prevents him/her from seeing well at night or in poor lighting, so they need a light source."
The faculty member of Azad University continued: "Due to power outages and the unavailability of a light source at all times, we designed a bracelet that works with the voltage in the human body and does not need a charger or battery."
She pointed out: The metals used in this bracelet provide the possibility of conducting electrical voltage and turning on the light source with the help of electrolytes in the body.
Behbahani added: This product is designed not only for the use of visually impaired people but also for all users.
She stated that since the voltage of this bracelet is supplied by the electrical conduction created in the human body, it can also become a kind of rescue kit. She added: "if someone is trapped in the dark and If he is alive, so his body continues to provide the voltage needed to light the bracelet, and somehow sends signals to the rescue team."
According to Behbahani, different light sources have been developed so far; However, the need for charging and batteries are among the disadvantages of using these devices, none of which are present in this new bracelet, and it is made based on the needs of a person with vision impairment and night blindness.
She said: All the used parts in this bracelet, except for the light source, are Iranian, and it is possible to make one sample with complete Iranian parts.
"Currently, a knowledge-based company in the field of medical equipment is trying to invest in this bracelet to enter the market at a fair price," said the assistant professor of medical-bioelectrical engineering.
