The Sensor - Brochure

Utilizing advanced micro-electro-mechanical systems (MEMS) fabrication methods, a fluidic microchannel is embedded inside the silicon resonator. Figure 1. By suspending the silicon lever in vacuum and embedding the micro-fluidic channel within it, LifeScale is able to exploit the high Q of a vacuum system whilst at the same time allowing microbes suspended in fluid to pass through the resonator. In this way biological samples, such as living microbes, can be measured under physiological conditions. To measure a microbe, the change in resonant frequency of the sensor is monitored as the microbe passes along the micro-channel resonator from position 1 to 3, Figure 1.
