Triboelectric air filters

Triboelectric air filters use the triboelectric effect to capture and remove airborne particles, including dust, pollen, and pathogens. By generating electrostatic charges on filter materials, these filters enhance particle collection efficiency without the need for an external power source.

Examples on applications include:

•Ventilation systems for air purification in residential and industrial environments for improved indoor air quality, 
•Facemasks that can remove viruses, pollen and other harmful particles from the air when breathing.

The growing research in tribomaterials continues to drive innovations in sustainable energy, clean air technologies, and advanced sensing systems.
