Baidu air curtain air purification helmet makes riding a healthier
In 2015, Baidu introduced an innovative concept aimed at improving outdoor safety and health in polluted environments: the Air Curtain Air Purification Helmet. Designed to combat the rising issue of smog, this smart helmet was one of Baidu's latest "Blacktech" projects, currently under patent review. The device uses a groundbreaking air curtain technology that creates a protective barrier around the user's face, effectively filtering out harmful particles like PM2.5 from the surrounding air.
Developed by Baidu's Deep Learning Labs, the helmet is still in the prototype stage, but it promises to revolutionize how cyclists and pedestrians protect themselves from poor air quality. By controlling airflow parameters such as speed, direction, and pressure, the helmet draws in polluted air, purifies it through an internal filtration system, and then releases clean air in a controlled manner to form an air curtain. This ensures a continuous flow of fresh air around the user’s face, offering a more comfortable and healthier riding experience.
According to leaked design sketches, the helmet is expected to connect with a mobile app, allowing real-time monitoring of air quality inside the helmet. It may also integrate with Baidu's smart bike, DuBike, enabling features like GPS navigation, voice interaction, and health data tracking. These added functionalities make the helmet not just a tool for air purification, but a comprehensive smart wearable device.
Like other Baidu innovations such as Baidu Brain, Baidu Eye, and autonomous vehicles, the Air Curtain Helmet showcases the company’s advanced R&D capabilities. Industry experts praised its ability to fight haze while offering multiple high-tech features. For cyclists and urban commuters, this smart helmet could be a game-changer, combining practicality with innovation in a world increasingly affected by air pollution.
