Abstract: A fluid testing cassette may comprise a microfluidic channel extending having a constriction and a micro-fabricated integrated sensor within the constriction. In one implementation, the constriction is less than or equal to 30 μm. In one implementation, the cassette further comprises a nozzle connecting the microfluidic channel to the discharge reservoir, wherein a thermal resistor expels fluid within the microfluidic channel into the discharge reservoir.

Abstract: A method of microfluidic detection can include detecting, using an impedance sensor, an impedance of a fluid to indicate whether a threshold amount of fluid has been received in a reservoir of a microfluidic chip. The method can include initiating a test performed by the microfluidic chip on the received fluid when the threshold amount of fluid has been received.
