Abstract

In this paper, a new cost-effective and reliable high performance biomass sensor is presented. Compared to previous biomass sensors, the developed sensor shows a potential to detect smaller biological agents by producing a high quality output signal at atmospheric pressure. The biomass sensor is a micro machined silicon squared plate that is excited in the Lame bulk acoustic resonant mode at a frequency of 37.8 MHz, with quality factor of 10,000 and the mass sensitivity of-400 Hz/pg.
