A device that can create an air "curtain" that blocks 99.8% of viruses and pollution promises to revolutionize human health protection.
In an era where air-borne health threats remain a constant concern, a groundbreaking innovation has emerged from the University of Michigan, USA, that could revolutionize the way we protect ourselves from viruses and environmental pollution.
Imagine a device that protects you from airborne pollution without covering your face. That's exactly what the "Worker Wearable Protection Device" (WWPD) is doing. Created by a team led by associate professor Herek Clack at the University of Michigan, the smart gadget uses an invisible air curtain to block out harmful particles.
The device consists of a hard hat equipped with a visor containing downward-facing air nozzles. These nozzles create a curved air curtain around the wearer's face that is effective at blocking 99.8% of aerosol particles, including viruses. Even the air curtain itself that falls on the wearer's face is pre-treated to kill all viruses, pushing the protection level to nearly 100%.
This is done through a 4.5 kg backpack that houses the device's components. The backpack contains several key components such as a battery to power the system, electronics to control its operation, an air handling system to manage the airflow, and a non-thermal plasma module. The non-thermal plasma module is the highlight of the device. It generates low-temperature ionized gas that effectively kills viruses present in the air before they reach the curtain of air that falls on the user's face.
The protective gear, which is being tested at Michigan Turkey Producers, a poultry processing plant, puts workers at constant risk of contracting respiratory viruses from both their co-workers and the birds they handle.
Previously, these workers had to use paper masks, which presented a number of problems, including difficulty communicating effectively, frequent fogging of goggles, and the masks not being able to maintain a tight seal on the face throughout the workday. Furthermore, workers had to remove their masks when eating or drinking, leaving them temporarily unprotected. The new WWPD solves all of these problems while providing superior protection.
While the current model is designed for industrial environments, Taza Aya, the company commercializing the technology, plans to release a smaller, more stylish consumer version. CEO Alberto Elli expressed excitement about the early results and expects to launch a device similar to the WWPD, called the Worker Wearable, in 2025.
As people face more and more airborne pathogens, innovations like the WWPD cap offer hope of replacing face masks altogether. In the future, the WWPD could become a common device, providing an invisible but powerful shield.
Leading the trend, Mobile World has recently officially launched the program “buy a product - own a car” for customers shopping at the system. This is also the first time a mobile retail system has made a special promotion program, so many customers are interested in the information of this program.
According to the Mobile World system, the unit will hold a program to own a VinFast VF 3 electric car when purchasing a mobile product from August 1 to September 2024. On the day Mobile World opens for sale of new products in September, the system will announce the results of lucky customers owning a VF 3 car by drawing a number based on purchase information.
