The SandPiper is a smartphone attachment designed for people with respiratory problems, who need an easy and convenient way to monitor their lungs on the go. It is the latest in a long line of smartphone-centric health monitoring devices.
The SandPiper is essentially a simplified version of a spirometer, a device used to monitor airflow in the lungs. Users simply plug the device into the headphone jack of their iOS or Android device, and blow into one end of the unit. A sensor inside then generates electricity proportional to the velocity of air passing through it and measures the amount of air moving through the tube.
This information is then relayed to the SandPiper companion app, which can analyze specific air flow parameters such as lung capacity, speed of inhalation and exhalation, airflow limitations, etc.
