Scientists at the University of Illinois Urbana-Champaign have developed a portable, self-powered UVC device called the Tribo-sanitizer. This device utilizes the triboelectric effect to power a UVC lamp, effectively inactivating two bacteria (Escherichia coli O157:H7 and Listeria monocytogenes) responsible for foodborne illnesses. The Tribo-sanitizer’s ability to generate its own power makes it suitable for low-resource environments, and its cost-effectiveness could provide consumers with an affordable solution for surface disinfection.
