Abstract
A liquid propelling component includes a liquid channel, a circuit block. The circuit block includes a first conductor disposed in the liquid channel to be in contact with liquid in the channel and a second conductor insulated from liquid in the channel. The liquid propelling component further includes a memory storing a digital code that corresponds to an analog value of the second conductor under a predefined charge.
Claims19
