Abstract
In one embodiment, a sensor includes two plates that form a capacitor. A droplet passing between the plates changes the capacitance of the sensor, thereby triggering an amplifier coupled to the sensor to generate an output signal. The output signal is indicative of droplet characteristics and may be used to calibrate a mechanism that dispensed the droplet.
