The explosion of social media has greatly reduced the social cost between strangers and infinitely narrowed the social distance between them. There are fewer obstacles to seeking sexual partners through the Internet, leading to a higher occurrence of occasional sexual behaviour among strangers. Teenagers, the main participants in online dating, are more open-minded than older people and have a more casual attitude to sexual behaviour. Protection when engaging in casual sex is often forgotten. The absence of safe sex guidance has led to the rapid spread of sexually transmitted diseases, such as HIV/AIDS.

Our team is working on building a medical device that allows users to take a self HIV rapid test. The medical device will be sold online and offline. Users can take the highly accurate test themselves. It is easy to use and private. The result will be recorded on the app automatically when the test is complete. Follow-up support and recommendations will be offered if the test result is positive.

Also, teenagers often engage in unhealthy behaviour, such as staying up late, smoking and drinking, so it is particularly important to achieve early detection and early treatment of illnesses resulting from such unhealthy behaviour. Mainstream diagnosis of gastric cancer is usually done by gastroscopy in hospitals. Our goal is to create a convenient, fast and portable product that can allow the test to be done at home.
