The concept for the device began in 2014 at Imperial College London. Smart Peak Flow was invented to help people keep track of their asthma in a convenient way. In 2017, the final device was created and is the world’s first peak flow meter to use smartphone technology. This device is important because, in the past few decades, asthma care has mostly stayed the same. However, the number of mild to severe asthma cases is growing. This device helps those people with their condition by giving accurate information and what they can do to manage it better.
