Current Research Directions and Vision

Since the beginning, the focus of Breath Research was in exploring possibilities through acoustic/audio analysis with the goal of improving everyday health and fitness in an easy and accessible way. Our R&D efforts gave birth to the technology behind our myBreath app, the CPET Framework and our proprietary AAL.

We currently have an IRB approved study with Mayo Clinic focusing on an in-depth examination of pulmonary pathologies.


Experimental analysis of a breathing session with wheeze presence.

spirometry and Lung sounds

We have been investigating the  detection of respiratory flow dynamics and lung sounds (wheeze & crackles), their diversity, intensity and classification. Backed by Mayo Clinic for data collection and medical insight, we are building a well-populated and documented respiratory acoustic library with recordings from patients with asthma, COPD, cystic fibrosis and idiopathic pulmonary fibrosis.

We are exploring the acoustic detection and classification of flow dynamics and lung auditory artifacts to profile the acoustic breath signatures of early, mid and late stages of those chronic respiratory diseases.

For more information on wheeze, crackle and artifact detection also check our demos!


Chronic Obstructive Pulmonary Disease (COPD)

This branch is in its prenatal state but given the spread and gravity of the disease it's one of the main directions for the near future.

Information courtesy of the COPD Foundation:

COPD is an umbrella term used to describe progressive lung diseases including emphysema, chronic bronchitis, refractory (non-reversible) asthma, and some forms of bronchiectasis. The disease is characterized by increasing breathlessness.

COPD affects an estimated 30 million individuals in the U.S., and over half of them have symptoms of COPD and do not know it. Early screening can identify COPD before major loss of lung function occurs.

What are the signs and symptoms of COPD?

  • Increased breathlessness
  • Frequent coughing (with and without sputum)
  • Wheezing
  • Tightness in the chest

Idiopathic Pulmonary Fibrosis (IPF)

Information courtesy of the Mayo Clinic:

Pulmonary fibrosis is a lung disease that occurs when lung tissue becomes damaged and scarred. This thickened, stiff tissue makes it more difficult for your lungs to work properly. As pulmonary fibrosis worsens, you become progressively more short of breath.

The scarring associated with pulmonary fibrosis can be caused by a multitude of factors. But in most cases, doctors can't pinpoint what's causing the problem. When a cause can't be found, the condition is termed idiopathic pulmonary fibrosis.

What are the Symptoms of IPF?

  • Shortness of breath (dyspnea)
  • A dry cough
  • Fatigue
  • Unexplained weight loss
  • Aching muscles and joints
  • Widening and rounding of the tips of the fingers or toes (clubbing)


In parallel with our research we are working towards designing a customized headset to be used for exercise testing. This will enable the measurement of breathing patterns to optimize athletic performance and to screen for respiratory disease.
