Abstract
In some examples, a cartridge includes a printhead comprising a fluid feed slot, a fluid chamber formed between a nozzle layer and a passivation layer, the fluid chamber fluidically coupling the fluid feed slot and a nozzle of the nozzle layer, and a printhead-integrated sensor to sense a property of a fluid in the fluid chamber, the sensor including a ground electrode exposed to the fluid chamber through an opening in the passivation layer.
