The idea of creating a service for children with autism belongs to AutismCare, the Academic Park resident company. An important part of the service is a bracelet that can detect changes in the emotional state of a child, identify stressful state warnings, and notify parents or guardians about them. The development (and now upgrading) of the device is a project of Aleksandr Trofimov, a third-year student of the Faculty of Radio Engineering and Electronics, NSTU NETI.
Now a prototype of the bracelet and a test application with some functions are almost ready (location detection on request, notification of sudden changes in the state of heart rate variability or galvanic skin response. "So far, the device has not been adapted for a child's hand, since it is quite large," says the developer. "In the future, we plan to significantly reduce the size of the bracelet using modern components. There is an idea to use flexible batteries and spray them directly on the strap. Thus, the device will be as light and easy as possible for a child, with all the functions preserved."
Currently, the bracelet for children with autistic disorders has two sensors and a mobile data transmission system. In the near future, the developer plans to conduct a number of studies that allow the microcontroller to directly determine the change in the emotional state. The main difference between the bracelet for children with autistic disorders is that it is both a part of the service and an independent device. The bracelet sends the collected data to a cloud database where it is analyzed by a neural network. The parents or guardians of the child receive a warning about the stress level based on these data analysis.
"Aleksandr came to students design bureau Prometheus in his first year," says Aleksey Bizyaev, head of the bureau, senior lecturer of the Department of Construction and Technology of Radio Electronic Devices. "Here, he first worked on simple projects, and when he reached the level at which he learned to be personally responsible for the developments, he was recommended to join the project. That is, Aleksandr went through the usual path of a member of Prometheus student design bureau . When there was an opportunity to work on a joint project with a resident of the Academpark, he had already proved himself to be a resourceful developer. He has a special interest in developing systems for people with disabilities."
Aleksandr says that he is seriously thinking of linking his future career to the development of devices for people with disabilities.
