    Abstract: A microfluidic flow sensor may include a substrate having a microfluidic channel, an inert particle source to supply a fluid carrying an inert particle to the microfluidic channel and a sensor element along the microfluidic channel and spaced from the inert particle source. The sensor element outputs a signal based upon a sensed passage of the inert particle with respect to the sensor element. Portions of the microfluidic channel proximate the sensor element have a first size and wherein the inert particle provided by the inert particle source is to have a second size greater than one half the first size.

    Abstract: A microfluidic flow sensor may include a substrate having a microfluidic channel, a bubble generator to introduce a bubble into fluid that is directed through the microfluidic channel and a sensor element along the microfluidic channel and spaced from the bubble generator. The sensor element outputs a signal based upon a sensed passage of the bubble with respect to the sensor element. Portions of the microfluidic channel proximate the sensor element have a first size and wherein the bubble generated by the bubble generator is to have a second size greater than one half the first size.

    Abstract: A microfluidic device may include at least four interconnected microfluidic channels and a set of fluid actuators. The set of fluid actuators may include a fluid actuator asymmetrically located within at least two of the at least four interconnected microfluidic channels. Each of the at least four interconnected microfluidic channels may be activated to a fluid inputting state, a fluid outputting state and a fluid blocking state in response to selective actuation of different combinations of fluid actuators of the set.
