Abstract:
A system includes a microchannel analysis region, a first fluid actuation device, a second fluid actuation device, a sensor, and a controller. The first fluid actuation device is at a first end of the microchannel analysis region. The second fluid actuation device is at a second end of the microchannel analysis region opposite to the first end. The sensor is within the microchannel analysis region between the first fluid actuation device and the second fluid actuation device. The sensor measures an impedance of a fluid within the microchannel analysis region. The controller activates the first fluid actuation device to generate a first pressure wave in the fluid and activates the second fluid actuation device to generate a second pressure wave in the fluid. The first pressure wave and the second pressure wave converge at the sensor.
