Innovative projects, ranging from smart rescue suits to landslide warning systems, have won top prizes in numerous competitions. These are practical contributions, providing community solutions to global challenges.

Technology for the community

Tran Tien Anh (class 12A7), Team Leader of the SGB team,FPT High School Da Nang (Ngu Hanh Son ward), said that through research, the team found that the traditional rescue equipment of the rescue and relief forces is still not standardized. The positioning devices, sensors, and communication equipment are easily damaged, mainly providing passive protection, lacking the ability to automatically detect danger, monitor the wearer's health, or connect data. Therefore, the team researched, designed, and manufactured the "Smart Rescue Suit with Integrated CO2 Life Vest".

Tien Anh shared that the smart rescue suit provides both physical protection and integrates a CO2 life vest, survival sensors, GPS, IoT data transmission, SOS alerts, and an AI assistant. Specifically, the suit uses waterproof material and has reflective strips to enhance visibility in low-light conditions. The lightweight CO2 life vest can be quickly inflated in standby mode, creating buoyancy to keep the wearer safe on the water.

The electronic system is housed in concealed pouches, with hidden wiring channels and protective layers to minimize impact, wire breakage, or water damage. The central processor is an ESP32 microcontroller, allowing the system to easily receive data from heart rate sensors, body temperature, GPS, and the SOS button. This data is processed within the device and sent to the management system via a communication module such as a SIM/4G modem. Simultaneously, on a web-based control panel, the command center can monitor the wearer's location, identify them, track vital signs, and monitor alert status in real time.

“The product’s highlight lies in the combination of physical protection and digital technology , creating unique value compared to traditional rescue equipment. Regarding cost, the team aims to use readily available domestic components to reduce expenses and target mass production,” Tiến Anh shared.

Nguyen Ha Vy (class 11A9), a member of the SGB team, said that in the future, the team plans to develop the product in three directions: perfecting the technology; expanding connectivity; and commercializing it. The team hopes to continue optimizing the production process, standardizing the design, conducting safety inspections, and collaborating with fire and rescue units and disaster prevention and control command centers for testing.

This research won first prize in the 2025-2026 City-level Science and Technology Competition, organized by the Department of Education and Training; and second prize in the U-Invent 8 competition - national high school category, organized by the Vietnam-UK Research and Training Institute (University of Da Nang) in collaboration with the City Youth Union and the City Student Association.

Ms. Hoang Do Tu Quyen, the teacher guiding the SGB team, commented that the students have applied their knowledge to solve real-world problems and serve the community using technology. She believes that with more investment, testing, and evaluation on a larger scale, the product could become a potential solution to support rescue forces, militia, volunteers, and fishermen in Vietnam.

A powerful tool

To address climate change and landslide issues in mountainous and remote areas, five students from the CAC team at Le Quy Don High School for the Gifted (An Hai Ward) researched a "Landslide Detection and Warning System." This system won third prize at the Samsung Solve for Tomorrow 2025 competition, organized by Samsung Vietnam in collaboration with the Ministry of Finance and the National Innovation Center, to promote STEM education in Vietnam.

Le Anh Tu (class 12A5), team leader of the CAC team, said that the team has noticed an increasing frequency of landslides, threatening the lives and property of people. Therefore, the goal of the system is to detect and warn of landslides early, giving people time to respond, evacuate, and minimize damage.

The system consists of hardware and software. The hardware includes devices placed on slopes, foothills, and areas where landslides have occurred. Sensors collect data on humidity, rainfall, water saturation, and surface slope, combining this with geological data (cohesion, porosity) to calculate the landslide risk. If the landslide risk exceeds 70%, the system issues a warning via loudspeaker. The software is a website that updates all the information recorded by the hardware, giving authorities a comprehensive and accurate overview of the landslide situation in each area.

“The system will compile statistics on both large and small landslides and send notifications to the authorities, providing maximum support for the response and damage mitigation process. With these benefits, the team hopes the system will become a powerful tool for both the public and authorities in responding to landslides,” Anh Tú described the operating principle.

Le Duc Chinh (class 12A5), a member of the CAC team, said that the hardware cost about 400,000 VND, while the software is completely free. Regarding commercialization, the team plans to sell the product under license if agencies or organizations purchase and install it. If they expand into a commercial product, they will adjust the costs accordingly. In the future, the team will improve various types of sensors to adjust risk levels and hopes to cooperate with relevant authorities to deploy the system more widely.
