摘要： An ink jet printhead device includes a substrate and a plurality of thermal resistors on the substrate. Each thermal resistor includes first and second electrodes and a resistive layer extending therebetween. A polarity-changing driver is coupled to the plurality of thermal resistors and configured to change a driving polarity between the first and second electrodes of each of the plurality of thermal resistors.

摘要： An ink jet printhead device includes a substrate and at least one first dielectric layer above the substrate. A resistive layer is above the at least one first dielectric layer. An electrode layer is above the resistive layer and defines first and second electrodes coupled to the resistive layer. At least one second dielectric layer is above the electrode layer and contacts the resistive layer through the at least one opening. The at least one second dielectric layer has a compressive stress magnitude of at least 340 MPa.

摘要： A resistive microelectronic fluid sensor implemented as an integrated voltage divider circuit can sense the presence of a fluid within a fluid reservoir, identify the fluid, and monitor fluid temperature or volume. Such a sensor has biomedical, industrial, and consumer product applications. After fluid detection, the fluid can be expelled from the reservoir and replenished with a fresh supply of fluid. A depression at the bottom of the sample reservoir allows a residual fluid to remain undetected so as not to skew the measurements. Electrodes can sense variations in the resistivity of the fluid, indicating a change in the fluid chemical composition, volume, or temperature. Such fluctuations that can be electrically sensed by the voltage divider circuit can be used as a thermal actuator to trigger ejection of all or part of the fluid sample.
