Title: FLUID EJECTION DIES INCLUDING STRAIN GAUGE SENSORS
Abstract:
A fluid ejection system includes a fluid ejection die, a service station assembly, and a controller. The fluid ejection die includes at least one strain gauge sensor to sense strain. The service station assembly is to service the fluid ejection die. The controller is to receive the sensed strain from the at least one strain gauge sensor during servicing of the fluid ejection die and adjust or stop servicing of the fluid ejection die in response to the sensed strain exceeding a servicing threshold.
