AI-driven dynamic face mask adapts to exercise, pollution levels

Researchers reporting in ACS Nano have developed a dynamic respirator that modulates its pore size in response to changing conditions, such as exercise or air pollution levels, allowing the wearer to breathe easier when the highest levels of filtration are not required.

2 in 1 Face Mask Against Dust and Virus – Chula Health Innovation in the New Normal

Chula’s Faculty of Engineering joins hands with PTT to develop a 2 in1 face mask, an innovation that protects against PM2.5 dust particles and COVID-19 virus that can be reused more than 15 times, helps reduce waste, is pollution-free, and will be available for sale soon.

The Mask Matters: How Masks Affect Airflow, Protection Effectiveness

Even though it has been widely known that wearing a face mask will help mitigate the community spread of COVID-19, less is known regarding the specific effectiveness of masks in reducing the viral load in the respiratory tracts of those wearing them. In Physics of Fluids, researchers examined the effect of wearing a three-layer surgical mask on inspiratory airflows and the mask’s effects on the inhalation and deposition of ambient particles in the upper respiratory airways.

Face Masks Slow Spread of COVID-19; Types of Masks, Length of Use Matter

Using face masks to help slow the spread of COVID-19 has been widely recommended by health professionals. This has triggered studies of the materials, design, and other issues affecting the way face masks work. In Physics of Fluids, investigators looked at research on face masks and their use and summarized what we know about the way they filter or block the virus. They also summarize design issues that still need to be addressed.

Johns Hopkins Medicine Joins Top US Hospitals to Encourage Everyone to #MaskUp

Johns Hopkins Medicine, together with 100 of the nation’s top health care systems, representing thousands of hospitals in communities across the U.S., have come together with an urgent plea for all Americans — mask up, because wearing a face mask is one of the best ways to slow the surging COVID-19 pandemic.

Researchers Redesign the Face Mask to Improve Comfort and Protection

Imagine a reusable face mask that protects wearers and those around them from SARS-CoV-2, is comfortable enough to wear all day, and stays in place without frequent adjustment. Based on decades of experience with filtration and textile materials, Georgia Institute of Technology researchers have designed a new mask intended to do just that — and are providing the plans so individuals and manufacturers can make it.
