More Information
Summary:A microfluidic flow rate sensor includes a droplet within a channel and a droplet movement detector that generates a signal based on the position and/or movement of the droplet within the channel. A processor determines the flow rate of a fluid through the channel based on the signal received from the droplet movement detector. In one example, the droplet movement detector is an optical detector, such as a combination of a lens and an image capturing device. In other examples, the droplet is electrically conductive, and at least a portion of the channel is conductive or includes electrical contacts. The position of the droplet within the channel is determined by observing the electrical characteristics of the channel.
