Description

<p>There are various potentially hazardous particles dispersed in various environment, such as virus, exhaust gas, PM 0.1 and 2.5, endospore of bacteria, etc. One of the key issues to monitor the presence of such the particles is a development of particle sensor, which should work continuously for a long time. In order to realize such type of sensor, we have proposed and experimentally demonstrated a clogging-free sampling method for continuous sampling and sensing operation by applying liquid-gate concept. We fabricated a test device and evaluated using carbon toner as a model of carbon particulate in atmospheric air. As a result, it was still primitive, we successfully proofed the concept of liquid gate sampling as expected.</p>
