Researchers at Caltech have unveiled a groundbreaking smart mask, the EBCare (Exhaled Breath Condensate) mask, designed to monitor respiratory health by analyzing breath. Created by Prof. Wei Gao and his team, this innovative mask detects specific chemicals in exhaled breath, offering insights into conditions like COPD, asthma, and post-COVID-19 complications.

Unlike other smart masks, EBCare does not track breath rate or temperature but focuses on biomarkers by condensing breath into a liquid for analysis. The mask’s sensors, connected to a smartphone app, provide real-time health data. Clinical tests have shown its ability to measure nitrite levels for airway inflammation, ammonium levels for potential kidney issues, and even blood alcohol content. With a projected material cost of just one dollar, the EBCare mask represents an affordable, versatile tool for general health monitoring.
