This paper reports a laterally vibrating MEMS resonant vacuum sensor which senses ambient pressure based on the squeeze-film damping effect. The single-anchored double-ended tuning fork structure is proposed to minimize anchor loss and thermoelastic dissipation. The squeeze-film damping gap width is designed to be changeable for the purpose of adjusting the squeeze-film damping effect at different...
We present a novel method to determine human blood types on a centrifugal microfluidic disk. The disk spun on stepping motor features sequential aliquoting structures and receiving chambers where red blood cells coagulate. The bubble-free priming of the receiving chambers is governed by 2-stage centrifugal rotation, including metering fingers in the low frequency and receiving chambers in the high...
