In an era where airborne health threats remain a constant concern, the University of Michigan has developed a groundbreaking innovation that could revolutionize the way we protect ourselves from viruses and other harmful particles. Let’s explore this development and its potential impact on worker safety and beyond.

The ‘portable worker protection device’
Imagine a device that protects you from airborne viruses without covering your face. That’s exactly what the “Wearable Protective Device for Workers” does. Created by a team led by Associate Professor Herek Clack at the University of Michigan, this ingenious device uses an invisible curtain of air to keep harmful particles at bay.

How does the shield work?
The device consists of a helmet fitted with a visor that houses downward-facing air nozzles. These nozzles create a curtain of air that curves around the wearer’s face, effectively blocking 99.8% of aerosols, including viruses. But here’s the interesting part: the air itself is pre-treated to kill any viruses present, raising that level of protection to nearly 100%.

The science behind the shield
The magic happens in a 10-pound backpack that houses the brains of the device. This backpack contains several crucial components: a battery to power the system, electronics to control operations, an air handling system to manage airflow, and a non-thermal plasma module. The non-thermal plasma module is the star of the show. It creates ionized gas at low temperatures, effectively killing airborne viruses before they reach the air curtain.

Real-world shield testing
The portable worker protection device is currently being tested at Michigan Turkey Producers, a poultry processing plant. Here, workers face a constant risk of respiratory viruses from both their colleagues and the birds they handle. Previously, these workers relied on paper masks, which came with a number of problems. They found it difficult to communicate effectively, their safety glasses often fogged up, and the masks were unable to maintain a consistent facial seal throughout the workday. Additionally, workers had to remove their masks to eat or drink, leaving them temporarily unprotected. The new device solves all of these problems while providing superior protection.

Looking to the future of the shield
While the current model is designed for industrial settings, Taza Aya, the company commercializing the technology, has plans for a smaller, sleeker consumer version. CEO Alberto Elli expressed enthusiasm for the initial results and plans to launch the Worker Wearable in 2025.

Kurt’s key takeaways
As we continue to face the challenges of airborne pathogens, innovations like this give us hope for a future where we can work and interact safely without the limitations of traditional face masks. While there is still work to be done before this technology is widely available, early results are promising. Looking ahead to 2025 and beyond, the wearable protective device for workers could well become commonplace in workplaces and public spaces, offering an invisible but powerful shield against airborne threats.
