Abstract
The development of low-cost, small, lightweight portable particulate matter sensors with increased accuracy that can be worn permanently in work and health related environments is recently in high demand. A novel miniaturized sensing system which possesses the functions of separating and measuring the mass concentration of the aerosol particles is presented. The system comprises a plurality of microchannels to separate incoming particles depending on their size and integrates capacitance sensors in the channels to detect particulate matter. Simulations have been performed to optimize the design of the channel structures. Subsequently digital light projection 3D printing technique has been employed for manufacturing. The final design has been successfully used to demonstrate real-time detection of particles (10 μm) in air. This approach enables the realization of next-generation personal portable devices for detecting dust, pollution, contaminants, among others, and can be utilized for early warning or real-time intervention applications.
