Abstract Respirators, medical masks, and barrier face coverings all filter airborne particles using similar physical principles. However, they are tested for certification using a variety of standardized test methods, creating challenges for the comp

Radiative coupling of objects with outer space, through the atmospheric spectral transparency window, allows passive cooling below ambient temperature. Such passively created cold sinks can be used for converting ambient heat into other useful forms

We report on the experimental characterization of a mass-loaded silicon nitride membrane-based resonator, which we investigate towards the development of accelerometers for small amplitude acceleration sensing at low frequencies. We experimentally de

The particle filtration efficiency (PFE) of a respirator or face mask is one of its key properties. While the physics of particle filtration results in the PFE being size-dependent, measurement standards are specified using a single, integrated PFE,

To overcome the limitations of existing acoustic standards based on microphones, the optical method based on photon correlation has been considered as a potentially new primary standard. In this article, the experimental measurement and signal proces

Laser-induced ultrasonic measurement is a non-contact non-destructive technology that can be employed for the testing and assessment of surface defects. In order to improve the correct identification of defects, the full matrix capture (FMC) and tota

A new traceability chain for non-standardized acoustic sensors is proposed by using the absolute measurement method of acoustic pressures. The current traceability chain for sound-in-air measurements is based on the laboratory standard microphone. Ho
