AsthmaSense

AsthmaSense is a low-cost, wearable, multi-modal sensing system for reducing asthma-related emergencies by detecting/predicting the onset of asthmatic attacks in pediatric patients.

The AsthmaSense project is focused on measuring respiratory sounds and motion to identify early signs of asthmatic attacks in pediatric asthma patients. According to our medical team, these symptoms are not always easily identifiable by the patients until it is too late. By notifying the patient, or a caregiver, we can get them to help before an emergency occurs (even if that simply means alerting them to take their medication). The goal is to reduce emergency room visits or worse outcomes.

This novel device consists of three custom body microphones, an accelerometer, and a Bluetooth-enabled microcontroller. The three microphones capture sounds from the body as it transmits through the sternum and clavicles (this is known as bone conduction). The microphones only capture surface vibration, rejecting any audio in the air.
