“…A fabricated ZnO-based UV sensor was used in the experiment to measure light intensity in terms of conductance, or the inverse of electrical resistance (G = 1/R) 26 . As shown by Pathak, Park, and Cho, the reliability and repeatability of the sensor used in our experiment has been demonstrated through repeated testing 26 . The screen-printing method is considered as an inexpensive, time-saving, and scalable process to fabricate electronic components 27 .…”

With the spread of COVID-19, significant emphasis has been placed on mitigation techniques such as mask wearing to slow infectious disease transmission. Widespread use of face coverings has revealed challenges such as mask contamination and waste, presenting an opportunity to improve the current technologies. In response, we have developed the Auto-sanitizing Retractable Mask Optimized for Reusability (ARMOR). ARMOR is a novel, reusable face covering that can be quickly disinfected using an array of ultraviolet C lamps contained within a wearable case. A nanomembrane UVC sensor was used to quantify the intensity of germicidal radiation at 18 different locations on the face covering and determine the necessary exposure time to inactivate SARS-CoV-2 in addition to other viruses and bacteria. After experimentation, it was found that ARMOR successfully provided germicidal radiation to all areas of the mask and will inactivate SARS-CoV-2 in approximately 180 s, H1N1 Influenza in 130 s, and Mycobacterium tuberculosis in 113 s, proving that this design is effective at eliminating a variety of pathogens and can serve as an alternative to traditional waste-producing disposable face masks. The accessibility, ease of use, and speed of sanitization supports the wide application of ARMOR in both clinical and public settings.

Flexible electronic devices are widely used in daily life. Among them, flexible sensors are widely studied by their potential for extensive applications. Materials are one of the essential foundations for making electronic devices. Due to the excellent unique properties of organic and inorganic hybrid materials, they are widely used in the manufacture of flexible sensors. Flexible sensor technology is developed by combining organic and inorganic materials and these hybrid materials can ensure the high frequency and high‐speed conductive property of a device while making the device flexible. In this review, the main three elements of sensors are mentioned and the materials selections in different elements are reviewed. After investigating the materials’ performance requirements of sensors, the performance of hybrid materials in sensors is comprehensively summarized according to the type of the sensor. Finally, some challenges and future directions of development are summarized and presented for flexible sensors based on such promising materials.
