Smart inhaler for asthmatics

Manufactured using 3D printing, the inhaler features a piezo sensor that measures airflow as it passes through it. If the user breathes in correctly – and in doing so increases the airflow – a green LED lights up. But if an inadequate amount is inhaled, a red one illuminates. Two buzzes are also sounded; the first to signal when the user should start to inhale and the second to let him know when to stop holding his breath.

"I really like the thought that it could help other people who have difficulties with asthma. Quite a few of the problems people have are related to the fact that they're not getting the correct dosage from their inhaler. If this happens for a long period of time, a person's asthma can get worse and worse. It's a common problem. I wanted to design something which helped solve this and enabled people to know for certain that they have used their inhaler correctly", the inventor explained.

His prototype was on show for the University's Art and Design Degree Shows 2013.
