Abstract:
A fluid ejection system includes a fluid ejection die and a controller. The fluid ejection die includes a plurality of nozzles to eject fluid drops and a plurality of strain gauge sensors to sense strain within the fluid ejection die. The controller is to receive the sensed strain from each strain gauge sensor to determine a status of the fluid ejection die.
