FLUID TESTING SYSTEM

摘要

A fluid testing system comprises controlling hardware that serves to control an electric sensor on a fluid testing cassette. In one implementation, the controlling hardware is part of a cassette interface. In another implementation, the controlling hardware is part of the portable electronic device. In one implementation, the fluid testing system applies two different frequencies of alternating current are applied to two different electric sensors.

主权项

1. A fluid testing system comprising:
at least one microfluidic channel; a first electric sensor within a microfluidic channel to form a first electrical field within the microfluidic channel and to output a first base signal indicating an impedance of the first electrical field; and a second electric sensor within the microfluidic channel to form a second electrical field within the microfluidic channel and to output a second base signal indicating an impedance of the second electrical field; a frequency source; and a controller to output control signals controlling the frequency source to selectively apply a first nonzero frequency of alternating current to the first electric sensor and a second, different nonzero frequency of alternating current to the second electric sensor.
